How are sedimentary rocks formed?

• From magma cooling and solidifying

• From sediments collected at the bottom of rivers or seas and solidified

• From the metamorphosis of existing rocks under high pressure

• From volcanic ash layers compressing over time

What can also contribute to the formation of sedimentary rocks besides sediments?

• Lava flows

• Minerals or fossils

• Plant roots

• Lightning strikes

What is the process called when rocks are broken down by forces on Earth?

• Erosion

• Compaction

• Weathering

• Cementation

What are the smaller pieces that result from weathering called?

• Crystals

• Sediment

• Pebbles

• Clasts

What is erosion in the context of sedimentary rock formation?

• The process by which sedimentary rocks are formed

• The layers of sediment that build up over time

• The carrying away of sediments by wind, water, gravity, or other means

• When sediments stop moving and settle into the bottom of lakes, rivers, or oceans

What does deposition refer to in the formation of sedimentary rocks?

• The carrying away of sediments by wind, water, gravity, or other means

• When sediments stop moving and settle into the bottom of lakes, rivers, or oceans

• The process by which sedimentary rocks are destroyed

• The layers of sediment that build up over time

What leads to the formation of sedimentary rock?

• Erosion only

• Deposition only

• Compaction and Cementation only

• Compaction and Cementation after layers of sediment build up over time

What is the process called when lava or magma cools and solidifies to form igneous rocks?

What is magma called when it reaches the Earth's surface?

• Basalt

• Lava

• Granite

• Pumice

Igneous rocks with very large crystals are known as what type of igneous rocks?

• Metamorphic igneous rocks

• Sedimentary igneous rocks
