A floodplain is plain that has been
flooded. A landform is land that is in a
different form. A delta is a narrow
stream. Erosion is when a river slower
wears down a landform.

2. Pangaea
a.
The name given to Earth’s landmasses when it
formed one huge supercontinent.
3. Continental Drift Theory
a.
Forces within earth caused Pangaea to break apart
into continental plates and drift apart.
4. Mountain formation
a.
tectonic plates push together
b.
two plates collide and one moves up over the other
B. Earthquakes

Plates shake causing an earthquake
A fault is a break in Earth’s crust
where movement occurs.
C. Volcanoes

3.
Plates push against each other
creating cracks in the crust onto
Earth’s surface.
Heat within the mantle causes rock in
the lower plate to melt. This molten
rock is magma.
Lava is the name for magma that has
escaped onto the surface.
