are in a distant star.
The spectrum a star absorbs can identify are in a distant star. Astronomers can identify an element by its spectral lines, as well as its temperature and density within the star.
The magnetic field of the star can also be shown via the spectral line. How quickly the material is travelling can be determined by the line's spectrum. Because stellar spectra resemble blackbodies, it is possible to determine a star's temperature incredibly precisely by taking brightness measurements using two separate filters. Astronomers attain a perfect temperature: Compare the ratio of red to blue light after measuring the brightness of a star with two filters.

Will marine food sources keep up with human population growth?
The marine food sources will not be able to keep up with human growth population.
There isn't much space for hope. There doesn't seem to be enough water available for agriculture to produce enough food to feed the world's 9200 million inhabitants.
Already under water stress, the current population is made worse by the interaction between population expansion and climate change. Additionally, since the middle of the 1980s, worldwide fisheries landings have been dropping, which has added to the current crisis in food production.
The food-producing industry least dependent on the availability of freshwater, marine aquaculture (hereinafter mariculture), will be used to help feed humanity in the twenty-first century.
Although there is still room for growth in northern temperate regions, despite significant intensification (such as a 10-fold increase in the yield of Chinese freshwater aquaculture in 20 years), freshwater aquaculture is becoming increasingly spatially constrained in the tropics and subtropics due to rapid human population growth and the concomitant high requirements for direct use of water and land.

Imagine that you are planning to conduct field work and need to record earthquakes. What is the minimum number of seismometers you will need in order to locate the earthquakes?.
You will need a minimum of three seismometers in order to locate the earthquakes.
A seismometer is a tool used to measure ground vibrations caused by earthquakes, volcanic eruptions, and explosions. These, a timing device, and a recording device make up a seismograph in most cases. During an earthquake, seismic waves are launched into outer space.
The epicenter of an earthquake can be located using seismographs from at least three different places. Seismometers allow for earthquake detection and monitoring by converting seismic wave vibrations into electrical impulses that may then be visualized as seismograms on a computer screen. Seismologists study earthquakes and can use this knowledge to determine an earthquake's precise location and magnitude.

A place such as central pennsylvania, home of penn state’s university park campus, is fairly typical of the world in terms of rainfall. What happens to the rain that falls on central pennsylvania each year?.
Rain that falls on central Pennsylvania each year most of it is evaporated.
Life depends on water, and life is highly adept at utilising it. Trees consume practically all of the rain that falls when their leaves are out, and tree roots reach deep into the soil and draw up some of the water from cold-season rain and snowmelt.
Even though plants still receive the majority of water, a sizable portion of it does sink into the ground and run to streams (perhaps 1/3 of the total). Although much of the land is not paved and little water flows across natural surfaces to streams, the quantity of water that does flow across the surface is growing as we pave the terrain.
Direct rainfall into streams, lakes, and rivers is minimal because they make up such a small portion of the landscape. Although "frackers" need water mixed with additional chemicals for the recovery of natural gas, they do not use nearly as much water as trees do. Additionally, even if the precise chemical make-up of the frack waters is a trade secret, we are confident that it does not consist of soda!

What is mineral?
A mineral or mineral species is, generally speaking, a solid chemical compound with a very well-defined chemical composition and a particular crystal structure that occurs naturally in pure form in geology and mineralogy. Compounds found only in living creatures are typically not considered minerals according to geological definitions. However, some minerals, like calcite, are frequently biogenic or, in the context of chemistry, are organic molecules (such as mellite). Additionally, living things frequently produce inorganic minerals (like hydroxylapatite), which are also found in rocks. Rock, which is defined as any bulk solid geologic substance that is sufficiently massive and sufficiently homogeneous, is not a mineral. A rock can be made of a single type of mineral or it can be an amalgam of two or more different mineral types that have been spatially separated into different phases.

The scientific consensus is that human activities are responsible for the recent increase in global temperatures because they are strengthening the greenhouse effect.
There is broad scientific agreement that human activities are mostly to blame for the increase in global temperatures. Many scientific organisations' position statements and assessments of experts' opinions, many of which expressly concur with the Intergovernmental Panel on Climate Change (IPCC) synthesis reports, reinforce this consensus.
The increased greenhouse effect describes the heat brought on by increases in greenhouse gases caused by human activities.

What has globalization done to influence income and wealth inequality in the United States? Include the influence of the Industrial Revolution and geography in your answer. Why did Europe develop first?
Globalization's rise in recent decades has increased income inequality in the U.S. while benefitting the executives, according to a study done by the National Bureau of Economic Research which directly connects globalized commerce with a prominent wage gap in the country.
The global trade dynamics encountered a huge shift during this time frame – particularly in the 1990s and 2000s, which saw the signing of the North American Free Trade Agreement (NAFTA) and China joining the World Trade Organization. Both events have been acknowledged by globalization critics, especially by President Donald Trump, as key turning points for the U.S. economy.
Although, Europe represents only about 8 percent of the Earth's landmass, from 1492 to 1914, Europeans colonized more than 80 percent of the entire world, which started with the gunpowder technology. Though it was invented in China and used in Japan and Southeast Asia, the Europeans excelled at using it, which catered to their successful conquests.
Gunpowder was very important for conquering territory as it allows a small number of people to impose a lot of influence. The technology grew to include more than just guns: armed ships, fortifications that can resist artillery, and many more, and the Europeans became the finest at using these things.

The principal difference between a marine west coast climate and a Mediterranean climate is
In comparison to a Mediterranean climate, the West Coast's marine climate has milder annual temperatures. Due to the significant impact of midlatitude cyclones, Marine West Coast climates experience higher annual precipitation totals than Mediterranean climates, which are also more evenly distributed throughout the year.
The Mediterranean climate is what?A temperate climate sub-type known as a Mediterranean climate, also known as a dry summer temperate climate Cs, is characterized by dry summers and mild, wet winters.
The Mediterranean Basin, where this climate type is most prevalent, gave rise to the name of the climate. Mediterranean climate zones are typically found between roughly 30 and 45 degrees north and south of the equator, along the western coasts of continents.
The subtropical ridge, which grows toward the hemisphere's pole during the summer and migrates toward the equator during the winter as a result of the seasonal poleward-equatorward temperature variations, is the primary contributor to the Mediterranean, or dry summer climate.

Imagine that you are planning to conduct field work and need to record earthquakes. What is the minimum number of seismometers you will need in order to locate the earthquakes?.
I would need three as a minimum number of seismometers, in order to locate the earthquake.
The P- and S-wave arrival times at various seismometers are utilized to pinpoint the earthquake's exact location. The separation of the P- and S-wave arrival times indicates how far away the earthquake is from the seismometer, providing we know the relative speeds of the P- and S-waves.

If the earth’s tilt on its axis were to increase by 20 degrees, at what latitude would you find the tropic of capricorn?.
The tropics are at 43 degrees 27' and the polar circles are at 45 degrees 27'. It would be an interesting evolution to adapt to the rapid and dramatic changes in the seasons.
More tilt means more severe seasons—warmer summers and colder winters; less tilt means milder summers and winters. The axial tilt of the Earth (also known as the obliquity of the ecliptic) is approximately 23.5 degrees. Because of this axial tilt, the sun shines at different angles on different latitudes throughout the year. This is what causes the seasons. Uranus has the solar system's largest axial tilt.

Explanation:
To be parallel means the line second line will never cross as u keep moving along. 2 lines that never cross that have same direction.
So when you shift the y intercept( the y point on graph) the new line is on top of the old line. But the new line will never cross since the slope is same.
What type of rock is formed through the solid-state alteration of a previously existing rock, by heating, pressure, and/or chemically active fluids?.
Metamorphic rocks are the rocks that are formed through the solid-state alteration of a previously existing rock, by heating, pressure, and/or chemically active fluids.
The word "metamorphosis" literally means "shape transformation." Rocks undergo metamorphism, which is the structural, chemical, and mineralogical adaptation of solid rocks to the physical and chemical conditions imposed at depth below the surface.
Usually, metamorphism takes place below the surficial zones, where the processes of cementation, compaction, and sedimentation occur. When a rock is exposed to conditions that are different from those in which it developed, metamorphism may occur.
A rock that was once one type of rock but changed to another under the action of heat, pressure, or fluids without going through a liquid phase is referred to as metamorphic (without completely melting).
Every time rocks experience changes in heat, pressure, or exposure to chemically reactive fluids, they undergo metamorphic transformations. These fluids include a variety of gases and liquids that exist under pressure inside the Earth, mostly water and steam.
