chapter 2 assesment

Chapter 2 Section 1

1. Describe the different surfaces and geographical areas found on Earth. Earth's surface is made up of water and land. Seventy percent of Earth's surface is water, with only thirty percent land. The geographical areas that make up Earth are the lithosphere, which is the all of the land that makes up earth. there is also the hydrosphere which takes up all of the bodies of water that make up Earths surface. Also there is the atmosphere which has all of the air that we need to survive, it is basically a layer of air that covers the entire Earth. Finally there is the biosphere which is the part of the Earth that supports life, animals, humans and ext.

2. What point on Earth is the greatest distance from sea level? The greatest point away from sea level is Mount Everest. Mount Everest is 29,028 feet above sea level, located in the Himalayas.

Creative Writing: Agree or disagree with the statement: When small objects in space, such as meteoroids and comets, enter Earth’s atmosphere, they have no long-term effect on Earth’s lithosphere, atmosphere, or biosphere. Justify your conclusion. I disagree with this statement, because the comets or meteorites that enter Earth's atmosphere can affect the land in which it landed. The comet, or meteorite can create craters, fires, flatten cities and much more.

Chapter 2, Section 2

1. How do Earth’s layers contribute to the planet’s physical characteristics? Earths layers contribute to the physical characteristics of Earth by making the planet what it is today. Since Earth's surface is moved by volcanic and tectonic activity, it is slowly changing the surface of Earth. Since the planet is changing, its characteristics are changing slowly.

2. How do internal forces of change affect Earth’s surface differently from external forces of change? Internal forces of change deal with all faults and volcanoes. Also with earthquakes, and all of the internal layers of the Earth. External forces of change deals with weathering, and with all the different types of erosion. Basically it deals with anything that is on the outside of the Earth's layers.

Creative Writing: Describe how internal forces may have changed the surface of what is now North America over the past 225 million years. 225 million years ago all of Earths continents were together in a supper continent called Pangaea. Internal forces have moved all of the continents around the world, to what we know now. Just because the plates have hit each other and folded under each other. This reaction changed the original landmass into seven different continents. Probably in another million years Earth will slowly have changed.
