The identities of each unknown mineral are feldspar, quartz, and mica.
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.

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 device used to gauge ground tremors brought on by explosions, volcanic eruptions, and earthquakes. In most situations, a seismograph consists of these, a timing device, and a recording device. Seismic waves are sent into space during an earthquake.
Seismographs can be used to pinpoint the epicenter of an earthquake from at least three separate locations. By turning seismic wave vibrations into electrical impulses that may be seen as seismograms on a computer screen, seismometers enable earthquake detection and monitoring. Earthquakes are studied by seismologists, who can utilize this information to pinpoint an earthquake's exact location and magnitude.

D
The barometer holding steady means present weather should continue.
The boys got to know the day's weather would persist as the barometer holding steady means present weather should continue. The correct answer would be option D.
A barometer is a device that measures the variation in air pressure with altitude. In the year 1643, an Italian scientist named Evangelista Torricelli developed the barometer. He investigated the properties of mercury in a vacuum and developed the first barometer based on this research.
Every barometer should be lightly tapped before reading. Gently touch the glass while keeping an eye on the indication needle to see which way it moves. Whether the pressure is mounting or declining should be your first concern when reading a barometer. If the needle does not fluctuate, the barometer is "keeping steady," and the weather should stay the same.

Smooth air, poor visibility, fog, haze, or low clouds should be expected beneath a low-level temperature inversion layer when the relative humidity is high.
Humidity is the concentration of water vapor gift inside the air. Water vapor, the gaseous nation of water, is usually invisible to the human eye. Humidity indicates the likelihood for precipitation, dew, or fog to be a gift. Humidity relies upon the temperature and strain of the gadget or the hobby. The same amount of water vapor results in higher relative humidity in cool air than in warm air. An associated parameter is the dew point. The quantity of water vapor had to reap saturation increases because the temperature will increase. As the temperature of a parcel of air decreases it will subsequently reach the saturation point without adding or dropping water mass. The amount of water vapor contained inside a parcel of air can vary significantly.

energy from the sun drives the earth’s climate and weather. the most intense solar radiation arrives at the equator. solar radiation leads to the greenhouse effect, which is essential for life on earth. (a) there is evidence that global climate change over the past 100 years has led to an increased warming of earth because of the greenhouse effect. (i) describe how the solar radiation that arrives at the equator is redistributed around the earth through atmospheric circulation.
Answer:
Explanation:
The Sun doesn’t heat the Earth evenly. Because the Earth is a sphere, the Sun heats equatorial regions more than polar regions. The atmosphere and ocean work non-stop to even out solar heating imbalances through evaporation of surface water, convection, rainfall, winds, and ocean circulation. This coupled atmosphere and ocean circulation is known as Earth’s heat engine.
unequal heating forms Hadley cells that redistribute heat
-unequal heating forms convection currents that redistribute heat
-unequal heating forms wind currents that redistribute heat
-unequal heating alters ocean currents that redistribute heat
The climate’s heat engine must not only redistribute solar heat from the equator toward the poles, but also from the Earth’s surface and lower atmosphere back to space. Otherwise, Earth would endlessly heat up. Earth’s temperature doesn’t infinitely rise because the surface and the atmosphere are simultaneously radiating heat to space. This net flow of energy into and out of the Earth system is Earth’s energy budget.
The Earth is not heated uniformly by the Sun. The Sun heats equatorial regions more than polar parts because the Earth is a spherical.
What drives Earth climate and weather ?Through the evaporation of surface water, convection, precipitation, winds, and ocean circulation, the atmosphere and ocean continuously attempt to balance out solar heating imbalances. The Earth's heat engine is this circulation of the ocean and atmosphere together.
Uneven heating patterns Heat redistribution Hadley cellsConvection currents caused by uneven heating transfer heat.Wind currents caused by uneven heating redistribute heat.Uneven heating changes ocean currents, which redistributes heat.The heat engine of the climate must return heat from the Earth's surface and lower atmosphere to space in addition to redistributing solar heat from the equator toward the poles. Otherwise, the planet would continue to heat up. The heat of the planet because heat is simultaneously being radiated into space from the surface and the atmosphere.

The average yield for wheat has increased 3 times in the last 60 years.
The broad range in wheat production costs across the nation was due to variations in crop yields, cropping techniques, and the costs of land, labor, and capital assets. The variety in the types of wheat farmed in the United States, each with its own production methods and related expenses, is mostly due to regional climate variances. For instance, northern wheat growers opted for spring wheat varieties that were harvested in the fall because winter wheat, which was sown in the fall for summer harvest, would perish in the cold during its winter dormancy.
