ABOUT EARTH SYSTEMAs a system, Earth has four giant reservoirs that hold matter, and each of these reservoirs is an open system because both matter and energy from each reservoir can enter and exit.
The four Earth reservoirs which are a sub-system of Earth are:
1) The atmosphere, which is the mixture of gases that surrounds the Earth. The predominant gases are nitrogen, oxygen, argon, carbon dioxide and water vapor.
2) The hydrosphere, which is all the water on Earth, includes the oceans, lakes, rivers, underground water, and all snow and ice, with the exception of water vapor in the atmosphere.
3) Biosphere, namely all organisms on Earth, including various organic materials that have not undergone decomposition.
4) Geosphere, which is the solid part of the Earth, and is mainly composed of rock and regolith (loose rock particles that cover the solid part of the Earth).

The major evolutionary episode corresponding most closely in time with the formation of Pangaea was theA) Cambrian explosion.B) Permian extinctions.C) Pleistocene ice ages.D) Cretaceous extinctions.
The major evolutionary episode corresponding most closely in time with the formation of Pangaea was the Permian extinctions (B)
The formation of Pangea, a massive supercontinent that stretched from north to south, is suspected by some authorities to have been the cause of the Permian extinction. As a result of the movement of the continental plates toward one another, it is believed that multiple shallow-water marine basins, which were the primary habitat of the majority of marine invertebrates, were eliminated. Additionally, because of the formation of such a large landmass extending from north to south, the paths of ocean currents were altered, which led to changes in the temperature of the various regions. Pangea had already formed in its entirety by the middle of the Permian period, but the onset of the mass extinctions did not take place until the last 15 million years of this time period.

The heavier elements on earth formed by stellar nucleosynthesis during the life cycle of existing stars.It is stellar nucleosynthesis that forms the heavier elements on Earth.
Nucleosynthesis is the process of creating new atomic nuclei from pre-existing nucleons (protons and neutrons). It is thought that the primordial nucleons themselves formed from the quark-gluon plasma from the Big Bang when it cooled below two trillion Kelvin. Minutes later, starting with just protons and neutrons, nuclei from aton down to lithium and beryllium (both mass number 7) formed, but only in relatively small numbers. Then the fusion process essentially stops as the temperature and density decrease, as the universe continues to expand. This first primordial nucleosynthesis process can also be referred to as nucleogenesis.
Subsequent nucleosynthesis of the heavier elements required the explosion of heavy stars and supernovae. This happened theoretically because hydrogen and helium from the Big Bang (perhaps influenced by the concentration of dark matter), condensed into prime stars 500 million years after the Big Bang. The elements formed in stellar nucleosynthesis range in atomic numbers from 6 (carbon) to at least 98 (californium), which have been detected from the spectra of some supernovae. The synthesis of these heavier elements occurs as a result of either nuclear fission (including multiple slow and fast neutron capture) or nuclear fission, sometimes followed by beta decay.

Steep slopes is one of environments would likely have large clasts.
ABOUT DEGREE OF SLOPEThe degree of slope on the slope can be seen from the contour of the land. A little explanation, contours are land lines that connect from one point to another. There are also those who interpret the contour of the land as the elevation of a land or what is called topography.
To determine the contour, topography is carried out by looking at the contour lines, namely the horizontal line and the height line so that later you will see the ups and downs of a land surface. These contour lines can provide information about the average slope of the land (slope), calculations of excavation and embankment of the original soil surface.

Meteorites that strike the earth are predominantly composed of Stony Meteorites.
What materials make up meteorites?
They are primarily composed of iron-nickel metal, with only trace amounts of sulphide and carbide minerals. Many asteroids melted during radioactive element decay in the early solar system, and the iron they carried sank to the center to form a metallic core due to its density.
What are the meteorites that hit the Earth's surface?

(b) Air temperature always increases with height in the troposphere.(c) Air temperature usually decreases with height in the troposphere but sometimes increases.(d) Air temperature usually increases with height in the troposphere but sometimes decreases.
the answer for the given question is (b) Air temperature always increases with height in the troposphere.
What is troposphere?The troposphere, the first and lowest layer of the Earth's atmosphere, is where most meteorological events take place and comprises 75% of the planet's total atmospheric mass, 99% of the entire mass of water vapour, and aerosols. The troposphere is typically 18 km (11 km) above Earth's surface in the tropics, 17 km (11 mi) above it in the middle latitudes, and 6 km (3.7 mi) above it in the high latitudes of the polar regions in winter. This makes the troposphere's average height 13 km (8.1 mi; 43,000 ft). The functional atmospheric barrier that separates the troposphere from the stratosphere is the tropopause, which is located atop the troposphere.

What are the ideal conditions for a strong radiation inversion?
A strong radiation inversion occurs when the temperature in the lower atmosphere increases with height.
This occurs when the surface is cooling rapidly due to radiative losses, but the temperature above is being warmed by the trapping of longwave radiation.
Ideal conditions for a strong radiation inversion include clear skies, light winds, and calm conditions, as these allow the surface to cool rapidly and the inversion to form.
The inversion can be disrupted by the mixing of air by winds, cloud cover, or precipitation, which can break down the temperature gradient and lift the inversion layer.

The paths the planet and the moon take during their orbits
A brief summary paragraph of your model
In this model, the planet and its moon are shown in orbit around the sun. The arrows labeled “gravity” indicate the force of gravity exerted by the sun on the planet and its moon, causing them to be pulled around the sun.
What is the model?Generally, The arrows labeled “inertia” indicate the momentum that keeps the planet and its moon in orbit, once they have been set in motion. The path of the planet is shown as a larger, more circular orbit, while the path of the moon is shown as a smaller, more elliptical orbit.
In summary, gravity pulls the planet and its moon around the sun, while inertia keeps them in motion and on their paths. The force of gravity is stronger on the planet than on the moon, which is why the planet’s orbit is larger and more circular.
