Chapter 2 Section 1
1. The earth has several different types of surfaces and geographical areas. Earth's surfaces are made up of bodies of water and land. Water covers up to about seventy percent of the earth! A few of the geographical areas include rivers, oceans, lakes, mountains, islands, peninsulas, deserts, and faults. Another geographical area could be the ring of fire. The ring of fire is the ring of volcanoes, and an area that is liable to earthquakes.
2. The point on the earth that is the greatest distance from sea level is the very peak of Mount Everest. Mount Everest is in South Asia and is 29,028 feet above sea level.
(* The shore of the DEAD SEA is in Southwest Asia. It's the lowest dry land point below sea level, at 1,349 feet! *)
Chapter 2 Section 2
1. The earth's three main layers consist of the core, the mantle, and the crust. Our planet's crust is broken up into several plates, they are called the techtonic plates. Earth's layers contribute to the planet's physical characteristics by the moviement of techtonic plates. The movement of the techtonic plates have created the various mountain ranges, the fault lines, and earthquakes.
2. Internal Forces of Change affect Earth's surfaces differently than external forces of change. An internal force creates a new feature to the earth's crust whether its a new mountain range or a new island because of the movement of the techtonic plates. An external force would erode or wear away the earth's surfaces with the wind an water.
CREATIVE WRITINGS:
Section1- I believe that objects in space such as meteoroids and comets as they enter the earth's atmosphere DO have a long-term effect on the earth's lithosphere, atomosphere, or biosphere. They have a long-term effect because they can fall into the ocean, onto land or burn off gases that will pollute our air.
Section 2- Internal Forces may have changed the surface of what is now North america over the past 225 million years by the shifting of plates to create the two mountain ranges(Rocky and Appalachian). The internal forces could have also formed the crack in our country's coast known as the SAN ANDRES FAULT.
