Worksheet: Rapid Changes to Earth's Surface: Volcanoes, Floods, Landslides, and Earthquakes
In this worksheet, we will practice recognizing the processes that cause changes to the Earth's surface.
Where do most earthquakes happen?
- AMost earthquakes happen at the North and South Poles.
- BMost earthquakes happen along a fault line where Earth’s plates meet.
- CEarthquakes happen in every country in the world.
What is the effect of landslides, earthquakes, and volcanic eruptions on the surface of Earth?
- AParts of Earth’s surface change quickly
- BParts of Earth’s surface change slowly
What is the name given to the molten rock below Earth’s surface?
In 1935, An American scientist named Charles Richter invented a way of measuring the strength of earthquakes.
|Strength (Magnitude)||0-2||2-3||3-4||4-5||5-6||6-7||7-8||8 and above|
|Effects||Not felt by people||Felt a little by people||Ceiling lights swing||Walls crack||Furniture moves||Some buildings collapse||Many buildings destroyed||Total destruction of buildings, bridges, and roads|
What is the name of the scale used to measure the magnitude (strength) of earthquakes?
- AThe earthquake scale
- BThe Richter scale
- CThe Charles scale
At which magnitude on the Richter scale does damage to buildings, bridges, and roads occur?
- D8 and above
In the desert you can find hills made out of sand that are caused by wind erosion. What is the name given to these hills?
After a volcanic eruption, new land forms on top of the old land. What is the new land made from?
- BVolcanic ash
What is an earthquake?
- AA movement of rock, earth, or debris down a slope
- BA storm with a violent wind
- CA sudden movement of the Earth’s crust
An earthquake happens when large slabs of rock move against each other below Earth’s surface. The slabs touch each other at a fault line.
What is a fault?
