Can someone please fill in all the blanks??? THE CRUST… OR LITHOSPHERE
The is that part of the earth that has layers of and hardened rock, and is to the (air).
The atmosphere is the crust and outer space.
Every thing lives here in what we call the “”.
The crust is everywhere, even under .

WEATHERING AND EROSION
The crust is the layer that is exposed to the and affected by WEATHERING and EROSION.
weathering physically up rock.
One example is called action.
Water gets into cracks and joints in . Water gets in a crack, freezes and , over and over, eventually the rock.

happens when rocks and sediments are picked up and to another place by ice, , wind or .
is a major agent of Erosion, (along with wind and water).
Ice freezes on the , and plucks pieces from the as the glacier slides down.
TECTONIC PLATES
The crust of the Earth is broken into many called plates.
We call the edge of these plates “boundaries”.
These plates (crust) are being moved by from the currents of magma found in the below.
We call these CURRENTS

CONTINENTAL AND OCEANIC CRUST
The part of the that is above the (land) we call CONTINENTAL PLATES
crust (land) is typically from km(20 mi) to 50 km (30 mi) thick.
Parts of these plates can be the ocean as well.
Oceanic Crust 5km to 30 km thick.
The Plate is almost entirely under the ocean except for almost a thousand (Hawaii etc.)
Some plates are called PLATES: they have major land (crust above the Ocean)..North America..
MAJOR TECTONIC PLATES
1. North American
2.
3. Eurasian
4.
5. African
6.
7. The Pacific Plate (Oceania) (not a continental plate!)

HEIGHT ABOVE SEA LEVEL!
We literally measure the height of land by (Height Above Sea Level)
The average depth of the oceans (how deep the water is) is 3800 meters (3.8km).
The maximum continental elevation (Height above sea level) (abl) is about 8848 (8.8km )meters (Mt. Everest)
Deepest is about 10,000 meters (10km) (below sea level)
( Trench in Pacific Ocean).
Altitude relative distance from you to the ground.
If there are mountains or valleys under you, that will affect your altitude.

THE MANTLE
The mantle is the layer below the (crust).
The mantle is the layer of the Earth.
The mantle contains moving molten rock called .

CONVECTION CURRENTS and CEllS
Magma is heated at the , rises to the crust and is under the crust, sometimes breaking through (), cools and .
As it under the crust, it drags/pulls the crust with it.
This causes the plates to move, and or moving away from other.
When a plate moves, an is created.
The individual pockets of currents are called CONVECTION
When breaks through the crust we call it .
Lava can escape through “” creating , or along “” or cracks between two major , creating a long (hill).
(Mid-Atlantic Ridge)

OUTER CORE
The cored of the are like a ball of very metals.
The outer core is , molten .
The core of the is 2,300 km (1,400 mi) thick and composed of and

INNER CORE
The inner core is
The inner core of the Earth has and pressures so great that the metals are together and are not able to move.
The inner core is thought to be almost as hot as the sun.
