Sedimentary Environments and Rocks

Which process is most responsible for turning solid rock into sediment?

• weathering

• compaction

• depostion

• lithification

As streams leave the mountains full of sediment they create this type of sedimentary environment.

• delta

• braided river

• lagoon

• meandering river

Located high in the mountains these frozen rivers can transport both large boulders and fine sediment.

• braided rivers

• ice rivers

• meandering rivers

• glaciers

When a stream enters a lake, its current slows and deposits sediment in a fan shape to create this feature.

• reef

• meander

• delta

• sand bar

A sedimentary environment near shorelines that is exposed during low tide is a

• lagoon

• tidal flat

• reef

• beach

These sheltered coastal areas are great for swimming due to the calm warm water.

• tidal flat

• reef

• lagoon

• barrier island

Coral reefs and barrier islands are important coastal environments because

• they are beautiful

• they protect the shoreline from erosion

• they protect fish from predators

• they are great for sunbathing

• Biological Activity

• Frost and mineral wedging

• Oxidation

• Thermal Expansion

• Near-Surface Fracturing

• Frost and mineral wedging

• Thermal Expansion

• Biological Activity

Which type of chemical weathering has caused these iron-rich rocks to take on a rusty orange appearance?

• dissolution

• oxidation

• hydrolysis
