Geology Question - APES
1. Make a simple drawing of Earth’s three major zones. Describe the composition of the zones. Briefly explain the internal process of plate tectonics and the external geological process of erosion.
● Continental Plates (Crust)- consists of the continental crust, and the oceanic crust
● Mantle- solid rock, but under its rigid outermost part is a zone of very hot, partly melted rock that flows like soft plastic. The plastic is asthenosphere.
● Core- is very hot and has a solid inner part, surrounded by a liquid core of molten material
Starting with the acceptance of the continental drift started the theory of plate tectonics. It is thought that plate motion produces mountains, ocean ridge systems, trenches, and other formations in earth’s surface. In the mantle, the solid metal in the core melts in the mantle which rises to the top. As the material cools as it reaches the outer mantle the plates move over for the other melted metal. The two plates move towards each other and one is sub ducted back into the mantle. This is how the plates move. The process of erosion is when materials are either:
● dissolved, loosened, or worn away from one part of the earth’s surface
● deposited in other places
The streams are the most important agent of erosion and produce valleys and canyons. Some erosion is caused when wind blows particles of soil from one area to another. Human activities, particularly those that destroy vegetation, accelerate erosion.
2. List three types of mineral resources, and give examples of each. Clarify the relationship between identified resources and reserves.
● Metallic mineral resources- iron, copper, aluminum
● Nonmetallic mineral resources- salt, clay, sand, phosphates, and soil
● Energy Resources- coal, oil, natural gas, and uranium
Identified resources deposits of a nonrenewable mineral resource with a known location, quantity and quality, or whose existence is based on direct geological evidence and measurements. Reserves are
