• Dropping or leaving sediment in a location

• Breaking down rocks into sediment

Soil is created by

Over millions of years, weak carbonic acid can dissolve limestone to form -

• Cracks in rocks

• Caves and caverns

• Mountains and cliffs

Small pieces of rock that have been weathered from a larger rock are known as...

• sand

• sediment
