Sediments form from the process of __________
Weathering
100
Do the rate of earthquake increase during cold weather explain?
cold temperatures greatly affect the ground near the surface, it has no effect at greater depths. Near the surface, freeze and thaw cycles can weaken and break rock due to high water pressure. However, this is a phenomenon limited to near surface soil.
100
What are volcanoes caused by?
Volcanoes are caused when magma rises to the surface of the earth, and it causes bubbles of gas to appear in it. This gas can cause pressure to build up in the mountain, and it eventually explodes. When the magma bursts out of the earth, it is called lava.
100
What tectonic plate do we live on?
North American Plate
100
What is the largest tectonic plate?
North American Plate

What is weathering, and how does it occur?
Weathering is when rocks are broken down into smaller particles, there are many agents of weathering, such as wind and water.
200
How do Earthquakes occur?
Sudden release of energy.
200
Where is magma formed?
Magma is a mixture of liquid rock, minerals, and dissolved gases. It is formed by the melting of earth's mantle. Magma is found deep below the surface of the earth.
200
What two continents fit together like a jigsaw puzzle?
South America and Africa
200
How can a Convergent Boundary make volcanoes?
If one of the plates starts to go under the other, subducting plates.
300
What are the two types of weathering?
Chemical and Mechanical.
300
What is the epicenter and how is it caused?
The center of the Earthquake on the surface.
300
How long does it take magma to harden?
Basaltic lava flows can form crusts that are thick enough to walk on in 10-15 minutes but the flow itself can take several months to cool!
300
What was the name of the supercontinent that was once composed of all the continents.
Pangaea
300
What two plates border the Mid-Atlantic Ridge?
South American and African Plate.
400
What is frost wedging an example of?
Mechanical Weathering.
400
What is a seismometer, seismograph, and a seismogram?
Measuring units and tools.
400
What is purposes of vents in the volcanoes?
The trapped pressure from the volcano is released from the vent.
400
What is a Divergent Boundary, and list one example.
When two plates pull apart, Mid-Ocean Ridges, Seafloor Spreading and Continental Rifts.
400
What is the Ring Of Fire?
The Ring of Fire is an area where a large number of earthquakes and volcanic eruptions occur in the basin of the Pacific Ocean.
500
What type of rocks are there, and how are they formed?
Igneous, Sedimentary and Metamorphic.
500
What's is all the waves and how are they different?
S-waves, go at right angles. P-waves, push and pull.
500
How are volcanoes formed?
Volcanoes are formed when magma from within the Earth's upper mantle works its way to the surface.
500
List the three type of plate boundaries, and explain for full credit.
Divergent, Convergent and Transform Fault Boundaries.
500
What is the Continental Drift Theory, and who developed it?
Wegener, plates were once together and they are constantly moving.
