• color test

• streak test

• weight test

• size test

Multiple Choice

What physical property can be observed when we scratch a mineral with our fingernail?

• cleavage

Multiple Choice

What is cleavage?

• Cleavage is when a rock or mineral always breaks in some sort of pattern.

• Cleavage is when a rock or mineral has a certain color.

Multiple Choice

True or false:

A mineral will always be the same color as its streak in the streak test.

• True, the mineral is always the same color as its streak.

• False, some minerals will have a different streak color than the color they look on the outside.

The Rock Cycle

Multiple Choice

What is the rock cycle?

• The rock cycle is a process where people learn how to identify rocks.

• The rock cycle is a process where, over time, minerals become rocks and are continually changed into igneous, sedimentary, or metamorphic rocks.

Multiple Choice

What two things do minerals need to become rocks?

• water and sun

• sand and bones

• heat and pressure

Multiple Choice

Which landform has been created because of the rock cycle, weathering, and erosion?

• Grand Canyon

• Skyscraper

• Highway

Multiple Choice

True or false:

Sedimentary rock layers are formed when smaller rocks like sand are under pressure over a long period of time.

• True. Sedimentary rocks form when small layers are formed and new layers form over top.

• False. Sedimentary rocks form deep within volcanoes when magma turns cools.

Multiple Choice

What is another word for the hot lava that eventually cools to become igneous rock?

• Magma

• Sediment

• Erosion

Three Types of Rocks

Multiple Choice

What are the three categories of rocks?

• Color, Luster, and Hardness

• Minerals, Rocks, and Trees

• Igneous, Sedimentary, and Metamorphic

Multiple Choice

The word meta- in metamorphic means what?

• Meta means to be made of different minerals.

• Meta means to change from one thing to another.

• Meta means to be a rock formed from pressure.

Multiple Choice

What natural disaster could result in the formation of igneous rock?

• hurricane

• volcanic eruption

• flooding

• tornado

Open Ended

Random Rocks

Multiple Choice

Where are most rocks formed?

• in caves

• in the ocean

• on mountains

• underground

Multiple Choice

What is the difference between a rock and a mineral?

• Minerals are made up of ONE specific matter, but rocks are made up of more than one mineral/matter.

• Rocks are made up of ONE specific matter, but minerals are made up of more than one mineral/matter.

Multiple Choice

True or false:

Fossils found in bottom layers of rock are older than fossils found in the top layer of rocks.

• False, the top layers are older.

• True, normally the layers of rock tell us when plants and animals died.
