Sedimentary rock

Sedimentary rocks form from layers of sediment accumulating over time. As debris builds up, the lower layers experience increased pressure, transforming the sediment into rock. Common sedimentary rocks include sandstone and limestone, which are frequently found on the Earth's surface.

What is the initial process in the formation of sedimentary rocks?

• Melting of rocks

• Accumulation of sediment layers

• Cooling of magma

• Erosion of mountains

What happens to the lower layers of sediment over time?

• They melt

• They evaporate

• They are compressed

• They expand

Which process gradually changes sediment into rock?

• Compression

• Melting

• Evaporation

• Freezing

Which of the following is a common type of sedimentary rock?

• Sandstone

• Marble

• Basalt

• Granite

Where are sedimentary rocks most commonly found?

• Exposed on the Earth's surface

• On the ocean floor

• In volcanic regions

• Deep in the Earth's core
