Wind, ice, and water are causes of this movement of sediment.
What is erosion?
100
Water that falls from the clouds as rain, snow, sleet, or hail.
What is precipitation?
100
The energy source essential for life.
What is the sun?
100
Molten rock inside Earth
What is magma?
100
The shaking of the ground resulting from a sudden movement between rock masses in Earth's crust.
What is an earthquake?
200
In desert areas, daytime heating and nighttime cooling can cause rocks to crack. Water may get into cracks in rocks and freeze. The ice then expands with a force great enough to break the rock. Even the roots of trees can pry rocks apart. Name the following destructive force that breaks rocks into sediment.
What is weathering?
200
This term describes water in the form of a gas.
What is water vapor?
200
A complete spin on the Earth's axis.
What is a rotation?
200
The place where molten rock along with other materials including gases reach the Earth's surface.
What is a volcano?
200
The point on the Earth's surface directly above the point underground where an earthquake originates.
What is the epicenter?
300
This theory suggests that Earth’s surface is divided into a dozen or so slow-moving plates, or pieces of Earth’s crust.
What is the theory of plate tectonics?
300
The circulation of water from Earth's surface to the atmosphere and back.
What is the water cycle?
300
Regions that are marked by changes in rainfall rather than seasons.
What are the tropics?
300
This volcano type produces non-explosive eruptions in which relatively thin lava spreads out over a large area.
What is a shield volcano
300
Underwater earthquakes that send energy through sea waves.
What are tsunamis?
400
This region around the Pacific Plate is home to most of the world’s earthquakes and volcanoes.
What is the ring of fire?
400
The percentage of Earth's total water supply.
What is 3%?
400
The term that describes the 365 ¼ day trip Earth takes around the sun each year.
What is a revolution?
400
The opening through which lava flows.
What is a vent?
400
A break between different areas of rock along which movement may occur.
What is a fault?
500
These three layers separate Earth's interior.
What is the crust, mantle, and inner core?
500
A large area of slow moving ice.
What is a glacier?
500
Responsible for the change of seasons.
What is Earth's 23.5 degree tilt and revolution around the sun?
500
The most violent and explosive type of volcano.
What is a stratovolcano?
500
This is the scale that scientists use to measure the strength of an earthquake.
