Your friend tells you that sunlight breaks rocks into small pieces. How would you revise this statement, explaining how the process is more complicated than that.

• Sunlight doesn’t directly break rock into small pieces. Energy from the sun is transferred to Earth’s surface. It is then transferred into the air, which heats it up. This process causes wind; it causes clouds to form and storms to occur. This energy also makes it rain. The wind and rain break the rock down into small pieces called sediment. The wind and rain eventually move these pieces to a lower place in the landscape.

• Sunlight doesn’t directly break rock into small pieces. Energy from the earth's interior is transferred to Earth’s surface. It is then transferred into the earth, which heats it up. This process causes wind; it causes clouds to form and storms to occur. This energy also makes it rain. The wind and rain break the rock down into small pieces called sedimentary rock. The wind and rain eventually move these pieces to a lower place in the landscape.

• Sunlight does directly break rock into small pieces. Energy from the sun breaks the rock into many small pieces, just like a laser beam. The small pieces are called sediment. Sediment is then transferred by wind. The wind and rain break the rock down into small pieces called sedimentary rock. The wind and rain eventually move these pieces to a lower place in the landscape.

• This statement is perfectly correct.

How do weathering and erosion compare?

• Weathering breaks rocks into smaller pieces and erosion moves rocks.

• Erosion breaks rocks into smaller pieces and weathering moves rocks.

• Weathering uses wing power and erosion using rain to transform rocks.

• Weathering and erosion are exactly the same process.

How does magma form?

• Sediment is weathered

• Any rock is melted

• Any rock is cooled

• Sediment is cooled

• Only igneous rock is melted

How does sediment form?

• melting rock

• cooling rock

• weathering any rock

• weathering magma

• cooling magma

Sediment forms through __________1________________________ of rocks, which is caused by__________2_________________.

• 1-weathering, 2-energy from the sun

• 1-weathering, 2-energy from earth's interior

• 1-melting, 2-energy from earth's interior

• 1-melting, 2-energy from the sun

How does magma form? Place the following statements in the correct order for how magma is formed. 1- rock is exposed to energy from Earth’s interior. 2- part or all of the rock melts. 3- the rock is heated until it is 700 degrees Celsius to 1300 degrees Celsius. (Answer order=First, Second, Third)

• 1, 2, 3

• 1,3,2

• 2,1,3

• 3,1,2

• 3,2,1

Which type of rock can be transformed into sediment?

• sedimentary rock

• igneous rock

• both sedimentary and igneous rocks

• neither sedimentary and igneous rocks

How are igneous rocks formed?

• cooling magma

• compacting and cementing magma

• compacting and cementing sediment

• melting magma

• heat and pressure

What would happen if the igneous rock sample pictured was first exposed to energy from the sun and then millions of years later to energy from the Earth's interior?

• Energy from the sun would cause weathering to make sediment. Compaction and cementation would turn the sediment into sedimentary rock, and then energy from Earth’s interior would cause melting, and the rock would turn into magma.

• Energy from Earth’s interior would cause melting of the rock and turn it into magma. The magma would cool and turn into igneous rock. Then, energy from the sun would cause weathering to turn the rock into sediment.

• Energy from the sun would cause erosion to make sediment. Melting would turn the sediment into sedimentary rock, and then energy from Earth’s interior would cause melting, and the rock would turn into magma.

• Energy from the sun would cause cooling to make sediment. Uplift would turn the sediment into sedimentary rock, and then energy from Earth’s interior would cause melting, and the rock would turn into sediment.

When magma cools, it hardens to form

• igneous rock

• metamorphic rock

• sedimentary rock

• igneous and sedimentary rocks
