Earth's Spheres
A group of related objects or parts that work together to form a whole.
What is a system?
All of the matter, energy and processes within Earth's boundary.
What is earth system?
Process by which rock material is broken down by physical changes.
What is Physical weathering?
The process by which sediment and other materials are moved from one place to another.
What is erosion?
When eroded material is dropped.
What is deposition?
Mostly solid rocky part of the earth otherwise known as lithosphere.
What is Geosphere?
The layer of gases that surround the earth and where weather and climate occurs.
What is Atmosphere?
The process by which other chemicals combine with oxygen.
What is oxidation?
A fan shaped deposit that forms on dry land.
What is alluvial fan?
Where land and a body of water meets.
What is a shoreline?
The thin solid outer layer of the geosphere made of rock and soil.
What is Crust?
Contains flowing rock, solid, rocky later about 2,900km thick.
What is the mantle?
This causes chemical weathering in rocks to create underground caves.
What is groundwater?
The amount of water that a stream carries in a given amount of time.
What is discharge?
A flat area of land next to a river where many layers of deposited sediment can form. It naturally floods when water rises above its banks.
What is a floodplain?
Liquid due to extreme heat, made of nickel and iron, creates earth magnetic field.
What is the outer core?
A way to keep track of energy transfers into and out of the Earth.
What is Earth's energy budget?
Process by which the outer layers of rock slowly peel away due to pressure changes.
What is exfoliation?
Curves and bends that form a twisting, looping pattern in a stream channel.
What is a meander?
Bench of rock or flat rocky area found beneath the water at the base of a sea cliff.
What is Wave-cut platform?
Percentage of solar energy that is reflected back into space.
What is 30%
An decrease in greenhouse gases decreases the amount of energy radiated our to space.
True or False
False
The breaking down and wearing away of rock material by the mechanical action of other rocks.
What is Abrasion?
Forms when waves erode and undercut rock to make steep slopes.
What is Sea cliff?
The measure of the change in elevation over a certain distance.
What is Gradient?
