Earth's Powerful Forces of Change: Weathering and Erosion

Because it helps us predict natural disasters

Because it explains how landscapes are formed and changed

Because it tells us how plants grow

Because it helps us build stronger buildings

Weathering breaks down rocks and erosion moves the pieces

Erosion breaks down rocks and weathering moves the pieces

Both weathering and erosion break down rocks but do not move them

Neither weathering nor erosion affect rocks

Rocks expand during hot days

Rocks contract during cold nights

Rocks melt during hot days

Rocks crumble and flake over time

Ice wedging

Temperature changes

Acid rain

Wind erosion

Heavy sediments like pebbles

Medium sediments like sand

Fine sediments like clay

Organic sediments like leaves
