Answer: B. differentiation
Explanation:
Answer: The Earth is a closed system for matter
That is a list of all basic elemental materials on our planet. Because of gravity, matter (comprising all solids, liquids and gases) does not leave the system.
Answer:
the lithosphere is the solid, rocky crust covering the planet and the hydrosphere is composed of all the water on the planet
Explanation:
The lithosphere and the hydrosphere have numerous similarities, but also numerous differences. The biggest and most obvious difference between these two spheres of planet Earth is that the lithosphere is solid, rocky crust that covers the planet, while the hydrosphere is and is represented by all of the water on the planet. The crust is mostly made up by the volcanic activity, thus through the lava flows and crystallization of the magma, which have created the rocks, or with other words the crust, the land masses. The hydrosphere is represented by the waters, and it has been created by both water coming from the volcanoes, and from the space objects that have been falling on our planet. The waters are generally divided into two categories, saline and freshwater, with the saline being in much higher amount.
Newton realized that the reason the planets orbit the Sun is related to why objects fall to Earth when we drop them. The Sun's gravity pulls on the planets, just as Earth's gravity pulls down anything that is not held up by some other force and keeps you and me on the ground.
