Roca sedimentaria

Sedimentary rocks form over time as layers of sediment accumulate and are compressed under high pressure, transforming them into rock. Common types of sedimentary rocks include sandstone and limestone, which are prevalent on Earth's surface.

What is the primary process through which sedimentary rocks form?

• Accumulation of sediment layers

• Cooling of magma

• Erosion by wind

• Melting of ice

What happens to the lower layers of sediment as more layers accumulate on top?

• They experience increased pressure

• They become exposed to sunlight

• They melt into magma

• They are eroded by water

Which process transforms sediments into rock?

• Evaporation

• Compression

• Freezing

• Photosynthesis

Which of the following is a type of sedimentary rock?

• Granite

• Basalt

• Obsidian

• Sandstone

Where are sedimentary rocks most commonly found?

• In the Earth's core

• On the surface of the Earth

• In the ocean depths

• In volcanic regions
