1 Earth Movements 3 rd Grade Review

2 Find the word that fits the clue. A crack in Earth’s crust A. Continent B. Plate C. Fault D. 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 A. Vibration B. Plate C. Magma D. 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 B. Volcano C. Continent D. Plate

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

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

9 Vibration 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 A. Focus B. Fossil C. Fault D. 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 A. Plate B. Pangaea C. Fault D. 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 A. Magma B. Fault C. Focus D. 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 A. Seismograph B. Thermometer C. Vibration D. 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 A. Plate B. Pangaea C. Fossil D. 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 A. Magma B. Volcano C. Focus D. 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 A. magma, core, crust B. Crust, mantle, core C. Mantle, crust, plate D. 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 A. Flood B. Erosion C. Volcano D. 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 A. Convection currents in the mantle B. Earthquakes C. Currents in the core D. 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 A. Deposition B. Continental Drift C. Subduction D. 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 A. Mountains B. Valleys C. Canyons D. All of the above

31 All of the above Valley Canyon Mountain

32 Choose the correct phrase to finish the sentence. Subduction occurs when A. A magma chamber fills with molten rock B. Fossils are created C. Two plates collide and one slides under the other D. 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 A. The center of an earthquake B. A seismograph reading C. The crater of a volcano D. 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 A. Wind, waves, water, and plants B. Cast fossils and trace fossils C. Plates rubbing against each other D. Heat and pressure in the Earth

37 Wind, waves, water, and plants

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

39 Buildings falling and cracks in Earth’s crust

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

41 An area of volcano and earthquake activity.

42 Good luck on your test!!!!
