Rock Transformations

Which of the following are true about sedimentary rocks?

• They are formed from sediment

• They are created by energy from the sun

• They are created by energy from Earth's interior

• They take millions of years to form

How could a sedimentary rock change to an igneous rock?

• Being exposed to heat and pressure

• Being exposed to the sun's energy

• Being moved below Earth's outer layer, to Earth's interior

• Rocks can't change

Sand on a beach you're on appears to have pieces of sediment from surrounding rock formations. How is this possible?

• Wind and rain interacted with the rock, and it broke into pieces

• Rays from the sun shone on the rock and broke it into pieces

• The sand was formed by earthquakes, tsunamis, and other natural disasters

• If anything were left out for a long time, it would break into pieces

How do metamorphic rocks form?

• By melting and cooling

• By breaking into sediment

• By being cemented and compacted

• By being heated and put under pressure

Which of the following are true about igneous rocks?

• They can be transformed into other types of rocks

• They can be formed without energy

• They are formed from energy from the sun

• They are formed from energy from Earth's interior

True or false: sediment can form at Earth's interior

• True

• False

On a trip, you drive past a large rock formation. If you come home in 2 weeks and drive past it again, what can you expect about that rock formation?

• It will probably change a lot because rock is always changing and transforming

• The rock won't change at all because rocks can't transform

• The rock might change if it is the right season

• The rock is not likely to change much because rock transformation processes happen slowly

What happens at a convergent plate boundary?

• The plates hit each other and break into pieces, forming sediment

• One plate goes under another and sinks into the soft solid rock below

• The plates push against each other, causing them to bend

• One plate goes under another and sinks into the ocean

What determines if a rock is sedimentary, igneous, or metamorphic?

• How it is formed

• What country it is formed in

• What it is made of

• If it is edible or not

Can material from sedimentary rock form into igneous rock?

• No, igneous rock can only form out of igneous or metamorphic rock

• No, igneous rocks are formed underneath Earth's surface, and sedimentary rocks are formed at Earth's surface

• Yes, if sedimentary rock is exposed to the sun for long enough, it can melt and form igneous rock

• Yes, if sedimentary rock is moved to Earth's interior and exposed to energy there
