including the crust and upper mantle.
Hydrosphere-all the water on Earth.


The higher the slope of a stream or river, the
more erosion will occur. (gradient)
The more water in a river, the more erosion
will occur. (discharge)

As these giant sheets of ice move, they carve
into the surface of Earth, taking sediment
with them.

Events that build up Earth’s lithosphere and
cause the land to rise.

Magma from volcanoes hardens to form
igneous rock and volcanic mountains.
(subduction)


When plates collide, the lithosphere can be
folded up or down creating mountains.
Faults at transform plate boundaries can
create mountains.

The process by which eroded sediment is
dropped off or deposited in a new area.
