Oceans, lakes, rivers, and other bodies of water make up part of the Earth.
|
Hydrosphere
|
|
Land makes up a part of Earth called the ____, the Earths crust.
|
Lithosphere
|
|
Is the layer of gases extending above the planet's surface.
|
Atmosphere
|
|
The part of the Earth that supports life.
|
Biosphere
|
|
An underwater extension of the coastal plain.
|
Continental Shelf
|
|
The very center of the Earth that is solid and super-hot.
|
Core
|
|
Next to the outer core is a thick layer of hot, dense rock.
|
Mantle
|
|
The outer layer of the Earth.
|
Crust
|
|
The theory that the continents were once joined and then slowly drifted apart.
|
Continental Drift
|
|
All the physical process that create many of the Earth's physical features.
|
Plate Tetonics
|
|
When the plates spread apart ____ is pushed up from the mantle and ridges are formed.
|
Magma
|
|
The heavier sea plate divides beneath the lighter continental plate.
|
Subduction
|
|
Pieces of the earhs crust come together slowly as the sea plate slides under the continental plate.
|
Accretion
|
|
Sea plates that are pulled appart.
|
Spreading
|
|
Bends in layers of rock.
|
Fold
|
|
Cracks in the Earths crust.
|
Fault
|
|
Occurs when folded land cannot be bent any further.
|
Faulting
|
|
Breaks down rocks.
|
Weathering
|
|
Wears away the Earths surface by wind, glaciers, and moving water.
|
Erosion
|
|
When glaciers melt and recide, in some places they leave behind large piles of rock and debris.
|
Moraine
|
|
Is the name of this regular movement of water.
|
Water Cycle
|
|
Large bodies of ice that move across the Earths surface.
|
Glaciers
|
|
Is the changing of liquid water into vapor, or gas.
|
Evaporation
|
|
When warm air cools, it cannot retain all of its water vapor so the excess water vapor changes into liquid water.
|
Condensation
|
|
Rain, snow, or sleet; depending on climate
|
Precipitation
|
|
Turning ocean water into fresh water by removing the salt.
|
Desalation
|
|
Fresh water that lies beneath the Earths surface, comes from rain and melted snow that filter through the soil and from water that seeps into the ground from lakes and rivers.
|
Ground Water
|
|
An underground porous rock layer often saturated by very slow flows of water.
|
Aquifier
|
|
The big continent before the continental drift pulled it appart into 7 different continents.
|
Pangea
|
|
In the Pasific Ocean; in this area, it has the most earth quakes and volcanoes in the world.
|
Ring of Fire
|
|
The breaking down of rocks.
|
Physical Weathering
|
|
The changing form of rocks (ex. rust).
|
Chemical Weathering
|
|
Are small bodies that orbit the sun.
|
Dwarf Planets
|
|
Because they have solid, rocky crusts and support life (ex. Earth)
|
Terrestial Planets
|
|
They are more gasesous and less dense than terrestial planets even tho they are larger in diameter. (ex. Jupiter)
|
Gas Giant Planets
|
|
Are small irregularly shaped planet like objects.
|
Asteroid
|
|
Made of icy dust particles and frozen gasses look like bright balls with long feather like tails.
