Which rock type is born from "fire" or molten magma?

Igneous

100

A large rock cracks and breaks into tiny pieces after a cold winter. Is this Weathering, Erosion, or Deposition?

Weathering (Breaking)

100

Most of the Earth's water is found in the ocean. Is this Fresh Water or Salt Water?

Salt Water

100

True or False: A mineral is made of different types of rocks.

False (Rocks are made of minerals!)

100

What property are you testing if you rub a mineral across a white tile to see the color of the powder it leaves behind?

Streak

200

If you see a rock with many layers of sand and pebbles squeezed together, what is it?

Sedimentary

200

A river carries away mud and sand down to the ocean. Is this Weathering, Erosion, or Deposition?

Erosion (Moving)

200

When the sun heats up a puddle and it disappears into the air as a gas, what is that called?

Evaporation

200

Rain, snow, sleet, and hail are all types of _____________.

Precipitation

200

This property describes how a mineral reflects light. Is it "shiny" like metal or "dull" like chalk?

Luster

300

This rock type "morphs" into something new because of heat and pressure.

Metamorphic

300

A sand dune forms because the wind stopped blowing and dropped the sand in a pile. Is this Weathering, Erosion, or Deposition?

Deposition (Dropping)

300

Name two places on Earth where you can find Fresh Water.

Rivers, Lakes, Ponds, Glaciers, or Groundwater.

300

What do we call the solid, non-living crystals that are the "ingredients" of a rock?

Minerals

300

Scientists use the Mohs Scale to measure this property. It tests if one mineral can scratch another.

Hardness

400

This stage of the water cycle is responsible for making clouds.

Condensation

400

If a mineral breaks along smooth, flat surfaces, it has:

cleavage.

500

BONUS ROUND


Explain how a Sedimentary rock could eventually turn into a Metamorphic rock.

It has to be buried deep underground where it gets squeezed by pressure and baked by heat until it changes!
