types of Rocks

What is the difference between magma and lava?

• Magma is found deep beneath the Earth's surface, while lava comes out of a volcano

• Magma and lava are the same thing

• Magma is found on the Earth's surface, while lava is deep beneath the Earth

• Magma is solid rock, while lava is liquid rock

How do extrusive rocks form?

• When sediment settles in rivers, lakes, or oceans

• When rocks break down into smaller pieces over time

• When lava cools quickly on the Earth's surface

• When magma cools slowly beneath the Earth's surface

Where are sedimentary rocks formed?

• In caves when water drips and leaves behind minerals

• In places like rivers, lakes, or oceans

• On the Earth's surface

• Deep underground under high heat and pressure

What is lithification?

• The process of rocks breaking down into smaller pieces over time

• The process of water carrying away small pieces of rock and soil

• The process of compacting and hardening sediments to create solid rock

• The process of magma cooling slowly beneath the Earth's surface

What is dissolution?

• When rocks break down into smaller pieces over time

• When a substance dissolves in water and disappears

• When wind, water, or ice carries away small pieces of rock and soil

• When water in the atmosphere falls to the ground

What causes erosion?

• Wind and rain carrying away soil and rocks

• Water in the atmosphere falling to the ground

• Volcanic eruptions

• The process of compacting and hardening sediments

Where do metamorphic rocks form?

• On the Earth's surface

• Deep underground under high heat and pressure

• In caves when water drips and leaves behind minerals

• When lava cools quickly on the Earth's surface

What are stalactites and stalagmites?

• Formations in caves when water drips and leaves behind minerals

• Formations on the Earth's surface when lava cools quickly

• Types of extrusive rocks

• Types of sedimentary rocks

What is sediment?

• A type of sedimentary rock made from compacted sand grains

• Tiny particles like sand, mud, or pebbles that settle at the bottom of water bodies

• Rock that has melted into a liquid form

• A black rock that forms from compressed plant remains

What is coal?

• A type of sedimentary rock made from compacted sand grains

• A black rock that forms from compressed plant remains over millions of years

• A type of extrusive rock formed when lava cools quickly on the Earth's surface

• A type of metamorphic rock formed deep underground under high heat and pressure
