Test Date – January 6, 2017
Part One – Multiple Choice
 Know the layers of the Earth.
o Crust, Mantle, Core
 What forms when water slows enough to fill an area?
o Lake
 What landform is made when a river slowly cuts through rocks?
o Valley
 What force can rapidly change the Earth’s landscape?
o Volcanic Eruption
 When igneous rock from a volcanic eruption cools, what does it form?
o New Crust
 How does water break apart a rock?
o It takes up more space when it freezes in the cold weather.
 What carries soil away from hilly farm fields?
o Rain
 What cause a rockslide?
o Gravity
 How does erosion mainly occur in dry regions?|
o Sand particles blow against rocks.
 What force causes rocks breaking into smaller and smaller pieces?
o Weathering
Part Two – Short Answer
 Explain how an earthquake can change Earth’s surface.
o The vibrations move as waves that travel back and forth and up and
down along the Earth’s surface. These waves can cause cracks and
piles of rubble in landforms near where parts of the crust are
moved.
 As a tree grows, it can cause weathering. Explain how the roots of a tree
cause weathering.
o As the roots of a tree grow, they can push through soil and nearby
rocks. This pressure can help split the rocks into smaller pieces.
Part Three – Essay
Earth’s surface is constantly changing. Describe how erosion and weathering
change Earth’s surface. Explain how the processes are alike and different.
o Weathering is any action that breaks rocks into smaller pieces. The
formations made out of these rocks change shape over a long
period of time. Erosion is the movement of weathered material.
Both weathering and erosion change landforms over a long period
of time. Erosion uses the weathered particles to change the shape
of landforms while weathering produces the particles in erosion.
