PRAXIS 5005 Science Graded A+
Earth Sciences
1. What are the three main types of rocks?
Answer: Igneous, Sedimentary, and Metamorphic rocks.
2. What is the process of forming igneous rocks?
Answer: Magma cooling beneath the ground or lava cooling above the ground, resulting in crystal-like or
glassy rocks.
3. What is sedimentary rock composed of?
Answer: Weathered and eroded material that may have been previously igneous, sedimentary, or
metamorphic rock.
Plate Tectonics
4. What is plate tectonics?
Answer: The theory that the Earth's lithosphere is made up of major and minor plates that move with
the viscous part beneath them.
5. What are the three types of plate boundaries?
Answer: Transform boundaries, Divergent boundaries, and Convergent boundaries.
, 6. What happens at transform boundaries?
Answer: Plates slide past each other, causing friction and earthquakes.
7. What happens at Divergent boundaries?
Answer: Plates pull away from each other, creating new crust.
8. What happens at Convergent boundaries?
Answer: Plates push into each other, with one plate being subducted (pushed) under another.
Atmosphere
9. What is the composition of the Earth's atmosphere?
Answer: 78% Nitrogen, 21% Oxygen.
10. What are the layers of the atmosphere in order from lowest to highest?
Answer: Troposphere, Stratosphere, Mesosphere, Thermosphere, Exosphere.
Biology
11. What type of cells are animal and plant cells?
Answer: Eukaryotic cells.
12. What is a characteristic of Eukaryotic cells?
