Geosphere Layers
The lower part of the mantle beneath the asthenosphere. Is still a solid rigid layer despite the high temperatures due to the increased pressure caused by the layers above.

B. Mesosphere
C. Outer Core
D. Lithosphere
D: Lithosphere
Because of intense heat and pressure, scientists have only been able to dig about 7.5 miles down into the crust and lithosphere. What did scientists use to figure out the different layers of the geosphere that they could not get to?
A. Solar Radiation
B. Seismic Waves
C. Radio Waves
D. Heat Waves
B: Seismic Waves
How many full moons are there in a year?
12
The inner core is a solid layer of nickel and iron despite the extreme high temperatures found in this layer. Why is the inner core solid?
The inner core is solid because it is under enormous pressure.
The core of the Earth can be divided into two layers. What are these two layers called?
1. Inner Core
2. Outer Core
The geosphere has been divided into five different layers based on the physical properties of each layer. Write the names of these five geosphere layers in sequence from the outermost layer to the innermost layer.
1 correct = 500 points
2 correct = 1,000 points
3 correct = 1,500 points
4 correct = 2,000 points
5 correct = 2,500 points
1. Lithosphere
2. Asthenosphere
3. Mesosphere
4. Outer Core
5. Inner Core
Based on seismic wave observations, scientists have divided the geosphere into three layers. Name those three layers of Earth's interior.
1 correct = 500 points
2 correct = 1,000 points
3 correct = 1,500 points
* Answers can be in any order.
1. Crust
2. Mantle
3. Core
As you dig deeper into the geosphere, the temperature becomes very hot reaching approximately 4,000 to 5,000 degrees Celsius at the core. What is the cause of this intense heat?
The decay of radioactive elements (Uranium, Potassium, Thorium) along with heat left over from when the Earth was formed 5 billion years ago.
What allows the tectonic plates that make up the lithosphere to move?
The slowly flowing mantle rock of the asthenosphere.
What causes geologic events such as earthquakes, volcanoes, and mountain building to occur?
The interaction (movement) of tectonic plates at their boundaries.
