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.

Why river tend to be wider in the lower course than the upper course
The upper channel of the river is primarily engaged in erosion. Debris transported down from its upper and intermediate courses is carried downstream by the river as it moves across a wide, level plain in its lower course.
What is Erosion?Erosion is a surface process that involves the removal of soil, rock, or dissolved material from one area on the Earth's crust and the subsequent transport and depositing of the material at a different location. Weathering doesn't involve movement, unlike erosion, which does. A mountainside is being eroded as evidenced by the wind carrying away tiny rock fragments.A complete hillside paddock will experience sheet erosion when a thin layer of topsoil is lost, although it may not be immediately apparent.Learn more about erosion here:

The correct option for this question will be c. all of these.
What are greenhouse gases?
A greenhouse gas is a gas that both absorbs and emits heat infrared radiation, producing the greenhouse effect. Water vapour, carbon dioxide, methane, nitrous oxide, and ozone are the main greenhouse gases in the Earth's atmosphere.
What happens to the atmosphere as the concentration of greenhouse gases rises?
Positive climatic forcing, or warming, results from a rise in the atmospheric quantities of greenhouse gases. The cumulative warming effect from human-produced greenhouse gas additions to the Earth's atmosphere grew by 45% between 1990 and 2019.

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.

Answer:
D.
The government has made little effort to increase the status of women, increase family planning and contraceptive access, or encourage couples to limit family size.
Explanation:
Suppose you are on a ship sailing in the low latitudes. Write a paragraph explaining what might happen as you drift near the Equator.
The winds will gradually weaken until they stop as you float closer to the Equator. If you are in this area with very low wind, it would be preferable if you had access to a motor to help you move the boat.
Due to the curvature of the planet, temperatures decrease the farther a region is from the equator. On the east edges of continents, the humid subtropical climate is often found between 25° and 35° latitude. Additionally, temperatures drop as you travel farther from the equator.
Living near the equator will allow you to witness the world's fastest sunrises and sunsets, which only last a few minutes. Along with having a consistent twelve-hour day and night throughout the year, these locations also see less seasonal variation in day duration than regions north or south of the equator.
Scientists assert that there are several further reasons for hope in equatorial nations. They claim that because the area is on the western side of subtropical anticyclones, the Atlantic Ocean provides warm, humid air to the area. As a result, Brazil's tropical borderlands are particularly fruitful for farming.

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.

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.
Farmers in regions with plentiful rainfall were able to increase their potential output by using high amounts of fertilizer. At the opposite end of the spectrum, some places possessed lands that required expensive irrigation in order to grow a wheat harvest.
