The Earth System
A group of parts that work together as a whole.
What is a system?
The outermost layer made up of continental and oceanic land.
What is the crust?
The term geologist use for this underground water.
What is groundwater?
A large mass of ice that moves slowly over land.
What is glacier?
The moving of sediment from one location to another location.
What is erosion?
The ability to do work.
What is energy?
True or False : The deeper down inside Earth, the greater the pressure and temperature.
What is true?
The flat, wide area of land along a river that overflows during a flood.
What is a floodplain?
Many times in the past, continental glaciers have covered large parts of Earth's surface. These times are known as the...
What are ice ages?
The dropping of sediment.
What is deposition?
This acts as a major source of energy for Earth processes.
What is the sun?
Earthquake produced waves.
What are seismic waves?
As water moves over the land, it carries particles.
What is runoff?
As a glacier flows over the land, it picks up rocks using this process.
What is plucking?
The breaking down of rock and/or sediment.
What is weathering?
The Earth system has four main spheres. What are they?
What is the atmosphere, geosphere, hydrosphere, and the biosphere?
List the four layers of Earth's interior beginning with the outermost.
What is the crust, mantle, outer core, and inner core?
Sediment deposited where a river flows into an ocean or lake building this landform.
What is a delta?
Till deposited at the edges of a glacier forms a ridge.
What is a moraine?
List the four natural forces that have the ability to weather, erode, and deposit sediment over time.
What are wind, water, ice, and gravity?
These forces are responsible for the collision of tectonic plates that carries India with the plate that carries China, resulting in the formation of the Himalayan mountain range.
What are constructive forces?
The core is made mostly of these two metals.
What are iron and nickel?
The process that breaks down rocks through chemical changes creating caves or caverns.
What is chemical weathering?
A small depression or hole forms when a chunk of ice is left in glacial till.
What is a kettle or kettle lake?
This process occurs when waves carrying sediment wear away rocks along a coast (similar to weathering).
What is abrasion?
