Front 1

1. List the three types of evidence that support plate tectonics.

Back 1

1. Fit of the continents
2. Location of earthquakes, volcanoes, and midocean ridges
3. Distribution of fossils, rock types and ancient climatic zones.

Front 2

2. What are the 3 primary layers of the Earth?

Back 2

1. The cold, brittle lithosphere
2. A hot, convecting mantle
3. A dense, metallic core

Front 3

3. How large and how fast do lithospheric plates move and why do they move?

Back 3

Lithosphere plates move cm/year in response to the movements in the mantle.

Front 4

4. earthquakes

Back 4

sudden motions along breaks in the crusts called faults

Front 5

5. volcanoes and fissures

Back 5

– locations where magma reaches the surface

Front 6

6. What 3 geological features do plate motions cause? and list a geological representation in California.

Back 6

1. Mountains – Sierra Nevada Mountain Range
2. Faults – San Andreas Fault
3. Volcanoes – Mount Shasta

Front 7

7. Describe how scientists determine the epicenter of an earthquake.

Back 7

By triangulating info from three separate seismographs that determine the strength and focus of the quake.

Front 8

8. What 4 factors determine the severity of an earthquake?

Back 8

1. the size of the quake
2. the distance from the epicenter
3. the local geology
4. the type of construction

Front 9

9. What two creatures habitats’ are mostly affected by earthquakes, volcanic eruptions, landslides and floods?

Back 9

1. humans
2. wildlife

Front 10

10. What is rock composed of?

Back 10

Different combinations of minerals

Front 11

11. What four “natural” things provide many resources, including food, fuel, and building materials, that humans use?

Back 11

1. rocks
2. water
3. plants
4. soil

Front 12

12. What two things do fossils provide to the scientific community?

Back 12

1. Evidence about plants and animals from long ago
2. The past history of Earth.

Front 13

13. What is soil made of?

Back 13

Weathered rock and organic materials

Front 14

14. List 4 ways that soils differ:

Back 14

1. color
2. texture
3. capacity to retain water
4. ability to support the growth of many kinds of plants.

Front 15

15. What are the 3 types of rocks, and how are they formed?

Back 15

Igneous – Rock formed when molten magma cools and solidifies.
Sedimentary- Rocks that form when fragments of rocks and other debris are cemented together.
Metamorphic – Rocks that form when a rock is chemically changed by heat or pressure to form a new rock.

Front 16

16. What is the rock cycle?

Back 16

The Earth’s crust is made of recycled rocks. These are formed by external factors, such as heat, pressure, and weathering. These factors are continually breaking up and rebuilding sedimentary, igneous, and metamorphic rocks ina process known as the rock cycle.
