The rocking, swaying movement that occurs every 19 years is called the Metonic cycle.
The Metonic cycle constitutes 235 lunations, or synodic months, a 19-year period in chronology after which the Moon's phases repeat on the same days of the solar year or year of the seasons.
The Moon's phases repeat on the same days of the solar year, or year of the seasons, every 235 lunations, also known as synodic months. Athenian astronomers made the cycle discovery.
The Metonic cycle is a part of the following, more accurate approximation: 334 years equal 4131 insanities.
The Moon goes through a 19-year cycle known as the METONIC CYCLE, during which it precisely repeats its location in the sky (against the same constellation, at the same longitude).

comets
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.

An equation is ____
Graph the equations of the lines to check that they are parallel.
Answer:
y= 2x +4
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 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.

where does a medial moraine develop? group of answer choices in the middle of two coalesced glaciers. on the side of a glacier. at the top of a glacier. near the bottom of a glacier.
The correct answer is option A.
A medial moraine develops in the middle of two coalesced glaciers.
In geology, the point where two tributaries of glaciers meet together is called a medial moraine also called a deposited rocky material.
In general, a medial moraine is a rocky and surficial pathway or feature that lies in the middle of two glacial tributaries or glacial convergence points. It is formed when a rock wall falls in the middle and gets deposited there or when a rocky mud flowing along the way with the ice flow reaches in the middle and settles down there.
In general, a medial moraine is a long, narrow zone of rock and soil debris that is formed when two lateral zones of moraines join at the intersection of two glacial streams.

The correct answer is option B: degradation; diastrophism.
You are out at Papago Park, and you correctly identify that most of Papago Park is an eroded plain (called a pediment). The erosion that created this pediment means that degradation is faster than diastrophism.
The process during which earth materials are worn away and transported to far off places through natural forces such as water or wind is called erosion.
Erosion has wide range of forms and can occur from wearing away small layers of soil to the ground forming crates and deep holes.
In general, erosion is a natural process and erodes a specific portion of the soil through degradation process.
It forms holes in soil only when the degradation was happening at a faster rate in that soil than diastrophism.

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. Seasons are caused by this tilt.

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!

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.
So, concludingly, in general, tracings are made at three different or separate seismic stations ( that record the ground moments and display them in digital form as digital data), which are needed to locate the earthquake center point.

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.

What chemical reactions generate heat in the earth's interior?
Answer: There are three main sources of heat in the deep earth: (1) heat from when the planet formed and accreted, which has not yet been lost; (2) frictional heating, caused by denser core material sinking to the center of the planet; and (3) heat from the decay of radioactive elements.
