What is the main difference between weathering and erosion?
Weathering happens in place; erosion moves material
Both happen in place but at different speeds
Erosion happens in place; weathering moves material
Weathering is fast; erosion is always slow

Tree roots grow into cracks and slowly split the rock apart. What type of weathering is this?
Freeze-thaw weathering
Biological weathering
Deposition
Chemical weathering
20s
Why does freeze-thaw weathering break rocks apart?
Water shrinks when it freezes in cracks
Water expands when it freezes in cracks
Ice dissolves the minerals in the rock
Warm sunshine melts the rock surface

Rainwater is slightly acidic and slowly dissolves limestone. What type of weathering is this?
Physical
Chemical
Freeze-thaw
Biological

Sandstone
Limestone
Shale
Granite
30s
In the rock cycle, which processes turn layers of sediment into sedimentary rock?
Heat and pressure
Melting and cooling
Weathering and erosion
Compaction and cementation

Granite has large crystals, but basalt has small crystals. Why does granite have larger crystals?
It formed from layers of sediment
It cooled quickly at the surface
It was squeezed by great pressure
It cooled slowly deep underground
