3rd Grade Review

2. Find the word that fits the clue.
A crack in Earth’s crust
Continent
Plate
Fault
Magma

3. Fault
Most fault lines are deep in the crust, but some like the San Andrea’s fault can be seen on the surface.

4. Find the word that fits the clue.
Hot, flowing rock below Earth’s surface
Vibration
Plate
Magma
Fossil

5. Magma
The crust and mantle have areas of molten rock called magma. When a volcano erupts, magma comes to Earth’s surface.

6. Find the word that fits the clue.
Huge land mass that may have existed 200 million years ago
A. Pangaea
Volcano
Continent
Plate

7. Long ago, Earth had just one huge continent called Pangaea.

8. Find the word that fits the clue.
Rapid back and forth movement
Seismograph
Focus
Plate
Vibration

9. The energy given off in an earthquake sets off vibrations.

10. Find the word that fits the clue.
Remains of an organism that lived long ago preserved in rock
Focus
Fossil
Fault
Lava

11. Fossil
Fossils of tropical plants have been found on an island in the cold Arctic.

12. Find the word that fits the clue.
A sheet of crust and upper mantle that covers Earth’s surface
Plate
Pangaea
Fault
Continent

13. Plate
The surface of the Earth has many moving parts called plates. They are made of crust and upper mantle rock.

14. Find the word that fits the clue.
Place in Earth where the energy of an earthquake is first released
Magma
Fault
Focus
Volcano

15. Focus
When an earthquake occurs, the crust shifts and energy is released. The place energy is first released is the focus.

16. Find the word that fits the clue.
An instrument for measuring the strength of an earthquake
Seismograph
Thermometer
Vibration
Anemometer

17. Seismograph
Charles Richter developed the Richter scale to measure how much energy an earthquake releases. A seismograph is used to measure the strength of the earthquake.

18. Find the word that fits the clue.
One of the seven large land masses on Earth
Plate
Pangaea
Fossil
Continent

19. Continent
Continents are the parts of the curst that rise above the ocean. We live on the continent of North America.

20. Find the word that fits the clue.
Opening in Earth’s crust through which melted rock reaches the surface
Magma
Volcano
Focus
Fault

21. Volcano
A volcano is a mountain with a vent. The vent goes down into the Earth’s surface. Hot liquid called magma flows up through the vent to the Earth’s surface.

22. Choose the correct phrase to finish the sentence.
The layers of Earth beginning with the hottest are
magma, core, crust
Crust, mantle, core
Mantle, crust, plate
Core, mantle, crust

23. Core, mantle, crust

24. Choose the correct phrase to finish the sentence.
The force that changes Earth’s surface most slowly is
Flood
Erosion
Volcano
Earthquake

25. Erosion
Sediments and soil may be moved by wind, water, and gravity. This movement is called erosion.

26. Choose the correct phrase to finish the sentence.
Earth’s plates are always moving because of
Convection currents in the mantle
Earthquakes
Currents in the core
Earth’s rotation

27. Convection currents in the mantle
Heat from the mantle makes the plates move. This heat forms convection currents. The convection current is the movement of a heated substance.

28. Choose the correct phrase to finish the sentence.
New crust forms where magma rises at mid-ocean ridges. This is known as
Deposition
Continental Drift
Subduction
Ocean-floor Spreading

29. Ocean-floor spreading
As magma cools it hardens and forms new crust. This process is called ocean-floor spreading.

30. Choose the correct phrase to finish the sentence.
Examples of landforms are
Mountains
Valleys
Canyons
All of the above

31. All of the above
Valley
Mountain
Canyon

32. Choose the correct phrase to finish the sentence.
Subduction occurs when
A magma chamber fills with molten rock
Fossils are created
Two plates collide and one slides under the other
Erosion takes place

33. Two plates collide and one slides under the other
The light continental crust slides up over the heavier oceanic crust. The oceanic crust is forced down. It slips into the mantle. This is called subduction.

34. Choose the correct phrase to finish the sentence.
The term Ring of Fire refers to
The center of an earthquake
A seismograph reading
The crater of a volcano
An area of volcanic activity around the Pacific Ocean

35. An area of volcanic activity around the Pacific Ocean

36. Choose the correct phrase to finish the sentence.
Weathering is the breaking down of rocks into smaller particles by
Wind, temperature, water, and plants
Cast fossils and trace fossils
Plates rubbing against each other
Heat and pressure in the Earth

37. Wind, temperature, water, and plants

38. Choose the correct phrase to finish the sentence.
Evidence of an earthquake includes
Lava flowing down a mountain
Buildings falling
Cracks in Earth’s crust
Fields buried in ash
Both B and C

39. E: Both B and C Buildings falling and cracks in Earth’s crust

40. Choose the correct phrase to finish the sentence.
What is the Ring of Fire?
The Polar Region
A place where tornados occur
An area of volcano and earthquake activity.
A area with an unusual amount of wild fires.

41. An area of volcano and earthquake activity.

42. Good luck on your test!!!!
