Inside Earth Chapter 1 Review
| Question | Answer |
|---|---|
| This is the middle layer of the Earth which is located below the crust. | the mantle |
| This layer of the Earth's core is made of liquid. | the outer core |
| This is the outer layer of the Earth where the continents lie. | the crust |
| This layer is at the center of the Earth. It is a solid, hot ball of metal. | inner core |
| Who was the man who thought that the continents were once together and then separated? | Alfred Wegener |
| What occurs in the mantle that causes the plates to move? | The hot, melted lava pushes up through the crust. It is continually moving and pushing the plates outward as the hot lava hardens. |
| What type of evidence was found that helped to support that the continents were once together? | Fossil found on some of the continents, climate changes and plants found in areas where they couldn't have survived, mountains that are similar on different continents. |
| This is the name Alfred Wegener gave to the one large continent he thought existed many years ago. | Pangaea |
| What are the broken sections of the lithosphere that carry the continents and the ocean floor? | plates |
| What is the lithosphere and the asthenosphere? | 2 sections of the Earth's mantle, lithosphere=broken sections where the plates lie asthenosphere= lower layer of liquid |
| This is the name for a break in the Earth's crust. | a fault |
| What happens as you go farther down towards the center of the Earth? | the temperature gets higher and the pressure gets greater |
| What is rock? | ANY material that forms Earth's hard surface. |
| What is the device used to bounce sounds off underwater objects and then record the echoes to determine how far away an object is? | sonar |
| What is the study of our planet Earth? | Geology |
| Describe the two types of forces that make and shape Earth: constructive force and destructive force | Constructive Force-build up landmasses and mountains Destructive Forces- slowly wear away mountains and other features. |
| What are continents? | Landmasses surrounded by oceans |
| The process of adding new material continually to the bottom of the ocean floor is called | sea floor spreading |
| This is made up of Earth's crust and the solid part of the mantle. | Lithosphere |
| This is the layer in which the convection currents that move the plates occurs. | the mantle |
| Pangea was a main part of Wegener's theory of... | continental drift |
| As new crust forms on the ocean floor, it pushes the plates further and further apart. The Mid-Atlantic Ridge is an example of this movement called.... | sea-floor spreading |
| The lithosphere is made up of the crust and this part. | the upper mantle |
| This layer of the Earth contains convection currents that move the plates. | the mantle |
| Layers of similar rock and similar fossils helped scientists support this theory. | continental drift |
| This is the name of the place where two plates meet. | a plate boundary |
| This individual created the theory of continental drift. | Alfred Wegener |
| This is the name of the theory that states the Earth's lithosphere is broken into plates and carry the continents and the ocean floor. | plate tectonics |
| This is the longest chain of mountains located under the ocean. | Mid-Ocean Ridge |
| This is the name of the liquid rock that flows forth from volcanoes or breaks in the Earth's crust. | lava/magma |
| What pushed up through the mantle, causing the sea-floor to spread? | hot, melted magma |
| What is a plate and what does it do? | plates are broken sections of the lithosphere that carry and push the continents. |
| What does a geologist do? | he or she studies the featuer of Earth |
| What do you call the waves that occur during an earthquake? | seismic waves |
| What is the theory that the continents slowly moved over Earth's surface and spread apart over time? | continental drift theory |
| What is sea-floor spreading? | the continuing process of adding new material to the ocean floor. |
| Explain what the theory of plate tectonics is. | The idea that pieces of the Earth's lithosphere are in slow, constant movement, driven by the hot lava currents in the mantle. |
| According to continental drift, South America could have been part of this continent. Think of how we put the pieces together. What continent could it have been connected to? | Africa |
| These were found on both South America and Africa which helped support continental drift. | fossils of plants and dinosaurs |
| How are torn pieces of newspaper like the Earth's continents? | because if you match the pieces back up, they match perfectly |
| This type of boundary is when 2 plates MOVE APART | divergent boundary |
| These are the four layers of Earth. | inner core, outer core, mantle and crust |
| This type of plate boundary is when 2 plates collide or crash into one another. | convergent boundary |
| What is a transform boundary? | when 2 plates slip past one another. |
