Worksheet: Changes to Earth's Surface: Volcanoes, Earthquakes, Landslides, and Floods
In this worksheet, we will practice identifying, classifying, and describing quick changes to 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 sudden movement of the Earth’s crust
- CA storm with a violent wind
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?
- AA crack in Earth’s crust
- BA type of rock
- CA type of lava
A landslide is the movement of rocks, debris, or earth down a slope due to gravity.
Many things can trigger a landslide, such as earthquakes, melting snow, volcanic activity, or disturbance by human activities.
What do you think has caused the landslide shown in the diagram?
- AA volcanic eruption
- BMelting snow
- CAn earthquake
- DHeavy rainfall
The image shows what happens during a landslide. Which of the given definitions explains what a landslide is?
- AAn opening in Earth’s surface where molten rock is forced out
- BA type of earthquake
- CA sudden movement of soil from higher ground to lower ground
Earthquakes are caused by the movement of rocks below Earth’s surface. What happens to land during an earthquake?
- AThe land stays still.
- BThe land shakes.
- CThe land erodes.
A landslide happens when a large amount of rock and soil slide down a mountain. Which of these is evidence that a landslide might have occurred?
- APiles of dirt and rock on a roadway
- BWater overflowing a river
- CFlowing lava
Fill in the blank: Hot ash and lava are blown onto Earth’s surface when a volcano .
- Astops moving
- Ccools down
Fill in the blank: During a landslide, broken pieces of large and small rocks move downhill due to a force called .
