Lesson 2
outer layer
crust
plates
describe a cinder cone volcano
tall with steep slopes mostly ash
physical features on the Earth's surface
landforms
Wind can pick up rocks and crash them into things causing them to break down.
middle layer
mantle
how many plates total
12
describe a shield volcano
gentle slopes mostly lava
process of breaking rock into sediment
weathering
Glaciers scrape everything under themselves causing rocks to break.
center layer
core
plates pull apart
valleys form
fairly steep slopes mostly lava and ash
composite volcano
process of rocks moving
erosion
Explain how a valley glacier is formed?
When glaciers move down a mountain, they pick up sediment causing a U-shaped valley to form.
center layer - mostly liquid
outer core
plates slide past each other
earthquakes
measures earthquakes
Richter Scale
process of rocks being dropped
deposition
Glaciers that cover large areas of land.
continental glaciers
center layer - solid
inner core
plates collide
mountains form and volcanoes erupt
places where pieces of the crust move
faults
How can water cause weathering?
answers may vary
Explain how new land can form because of erosion and/or deposition?
Answers may vary.
