Ch 2 section 1:
1. The different surfaces and geographic features found on Earth are landforms and bodies of water. Landforms consist of man geographic features, such as continents, mountain ranges, cliffs, valleys, and deep trenches, and they often contain rivers, lakes, and streams. Bodies of water consist of oceans, lakes, rivers, peninsulas, seas, and others.
2. The point on Earth that is the greatest distance from the sea level is the peak of Mount Everest, which is at 29,028 feet above sea level.
Creative Writing: I agree with the statement that 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. When these small objects enter the atmosphere, they burn up and either become very small or disintegrate entirely. Even if they do survive, the most they could do is make a very small crater in the lithosphere, and that can be fixed very easily. Therefore, they have no long-term affect.
Ch 2 section 2:
1. The Earth's layers contribute to the planet's physical characteristics because tectonic plates that float on a partially melted layer in the upper portion of the mantle crash into each other, pull apart, grind, and slide past each other, changing the face of the planet.
2. Internal forces of change affect Earth's surface differently from external forces of change because they form and alter Earth's surface, while external forces of change break it down.
Creative Writing: Internal forces may have changed the surface of what is now North America by creating landscapes through spreading and colliding playes, folds and faults, earthquakes, and volcanic eruptions.
