Earth Movements 3rd Grade Review
A crack in Earth’s crust Continent Plate Fault Magma Find the word that fits the clue.
Fault Most fault lines are deep in the crust, but some like the San Andrea’s fault can be seen on the surface.
Hot, flowing rock below Earth’s surface Vibration Plate Magma Fossil Find the word that fits the clue.
Magma The crust and mantle have areas of molten rock called magma. When a volcano erupts, magma comes to Earth’s surface.
Huge land mass that may have existed 200 million years ago A. Pangaea Volcano Continent Plate Find the word that fits the clue.
Pangaea Long ago, Earth had just one huge continent called Pangaea.
Rapid back and forth movement Seismograph Focus Plate Vibration Find the word that fits the clue.
Vibration The energy given off in an earthquake sets off vibrations.
Remains of an organism that lived long ago preserved in rock Focus Fossil Fault Lava Find the word that fits the clue.
Fossil Fossils of tropical plants have been found on an island in the cold Arctic.
A sheet of crust and upper mantle that covers Earth’s surface Plate Pangaea Fault Continent Find the word that fits the clue.
Plate The surface of the Earth has many moving parts called plates. They are made of crust and upper mantle rock.
Place in Earth where the energy of an earthquake is first released Magma Fault Focus Volcano Find the word that fits the clue.
Focus When an earthquake occurs, the crust shifts and energy is released. The place energy is first released is the focus.
An instrument for measuring the strength of an earthquake Seismograph Thermometer Vibration Anemometer Find the word that fits the clue.
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.
One of the seven large land masses on Earth Plate Pangaea Fossil Continent Find the word that fits the clue.
Continent Continents are the parts of the curst that rise above the ocean. We live on the continent of North America.
Opening in Earth’s crust through which melted rock reaches the surface Magma Volcano Focus Fault Find the word that fits the clue.
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.
The layers of Earth beginning with the hottest are magma, core, crust Crust, mantle, core Mantle, crust, plate Core, mantle, crust Choose the correct phrase to finish the sentence.
The force that changes Earth’s surface most slowly is Flood Erosion Volcano Earthquake Choose the correct phrase to finish the sentence.
Erosion Sediments and soil may be moved by wind, water, and gravity. This movement is called erosion.
Earth’s plates are always moving because of Convection currents in the mantle Earthquakes Currents in the core Earth’s rotation Choose the correct phrase to finish the sentence.
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.
New crust forms where magma rises at mid-ocean ridges. This is known as Deposition Continental Drift Subduction Ocean-floor Spreading Choose the correct phrase to finish the sentence.
Ocean-floor spreading As magma cools it hardens and forms new crust. This process is called ocean-floor spreading.
Examples of landforms are Mountains Valleys Canyons All of the above Choose the correct phrase to finish the sentence.
All of the above Valley Mountain Canyon
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 Choose the correct phrase to finish the sentence.
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.
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 Choose the correct phrase to finish the sentence.
Weathering is the breaking down of rocks into smaller particles by Wind, waves, water, and plants Cast fossils and trace fossils Plates rubbing against each other Heat and pressure in the Earth 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 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. Choose the correct phrase to finish the sentence.
