Earth Science Questions with Correct Answers (Grade A+)
Question 1: Plate tectonics
Answer: theory that explains the:
- movement of the continents
- changes in Earth's crust caused by internal forces
Question 2: Plates
Answer: rigid blocks of crust and upper mantle
- move along the hot upper mantle
- make up the lithosphere
Question 3: Divergence
Answer: - 2 plates move away from each other
- hot mantle rock rises
- creates new sea floor
- creates new oceanic crust (2-10 cm per yr)
-Mid-Atlantic
Question 4: Convergence
Answer: - crust collides with another oceanic plate or continental plate
- oceanic crust sinks
- forms a trench
- forms volcano activity
- continent to continent plate collisions
Question 5: Subduction
Answer: - oceanic plate, dense, slides under continental plate
- oceanic plate plunges into the mantle
- forms a trench
Question 6: Trench
Answer: - forms b/c of subduction
- may cause a volcano
Question 7: Transform Fault
Answer: - 2 plates slide past one another
- parallel

, Question 8: Rifting
Answer: - sea floor spreads
- occurs at mid-ocean ridges
- Red Sea
- new material is added to inner edges of separating plates
- plates grow larger, ocean basin widens
- how Pangaea was broken
- created Atlantic Ocean
Question 9: Atmosphere - Dry air components (3)
Answer: - dry gas
- water vapor
- solid particles (dust from soil, etc.)
Question 10: Atmosphere dry gases (4)
Answer: (N2) Nitrogen - 78.09% (O2) Oxygen - 20.95% (Ar) Argon - 0.93% (CO2) Carbon Dioxide -
0.03%
Question 11: Atmosphere (4 layers) - temperature based
Answer: Troposphere (earth) Stratosphere Mesosphere Thermosphere (space)
Question 12: Troposphere
Answer: - closest to Earth's surface
- weather here
- most water vapor/dust
- increasing altitude = air temp down
- 7 miles long
Question 13: Stratosphere
Answer: - little water here
- clouds are rare
- OZONE LAYER
- air temp = constant, increases with height (absorbs solar energy & ultraviolet rays from ozone layer)
Question 14: Mesosphere
Answer: - air temp decreases with height
- coldest layer
