Chapter 2, Section 1

1. The hydrosphere are the oceans, lakes, rivers, and other bodies of water that make up 70% of the Earth's surface. The lithosphere makes up about another 30% of our planet, which includes the continents, islands, and the ocean basins of Earth. The atmosphere is a layer of gases extending above the Earth's surface and is composed mostly of nitrogen and oxygen. The part of the planet that supports life is the biosphere, which naturally takes place in the atmosphere and around the area of the lithosphere.

2.The Mariana Trench, located in the Pacific Ocean southwest of Guam, is at the greatest distance from sea level.

When objects from space land on the Earth, they can devastating effects on the areas of the world. On impact of the lithosphere, large meteorites can destroy hundreds of miles of land and any creatures of the biosphere in its path, making it so those creatures could never have offspring, so in the long run, millions of creatures could have been born if not for those deaths. The same effects could be seen if it landed in the hydrosphere as well, as the shock waves could have killed several marine animals.
