This question is about sedimentary rock.

2

Sediment can be formed from rocks by weathering and erosion.

Match up each term to its meaning.

Draggable item		Corresponding Item
Sediment		Breaking down of rock into smaller pieces in one place.
Weathering		small pieces of rock are moved by water, ice or air.
Erosion		Small pieces of solid moved and dropped in a new location.

2

Rocks can be weathered by physical, chemical and biological processes. Decide if the example is of a chemical, physical or biological process and explain your answer. Some rocks can be weathered by normal rainwater. The rainwater reacts with certain minerals in the rock to form a salt that can dissolve away and carbon dioxide gas.

2

Decide if the example is of a chemical, physical or biological process and explain your answer.

Water can get into the cracks in rock. If the temperature drops below 0 oC it will freeze, expand and push on the rock. If this happens many times it can break the rock into smaller pieces.

Sedimentary rock can be formed at the bottom of the ocean over millions of years. Sandstone is a sedimentary rock made from sand grains by sedimentation, compaction and cementation.

Match the three words to their meanings.

Draggable item		Corresponding Item
Compaction		Layers of sediment collecting in one place
Cementation		Sediments getting squashed closer together
