Unit 4 Part 2 Rocks and Minerals Common Assessment Review

If during the investigation it is found that mineral A can scratch Mineral B, but Mineral B cannot scratch Mineral A, then which of these statements is true?

• Mineral A is smoother than Mineral B.

• Mineral A is rougher than Mineral B.

• Mineral A is harder than Mineral B.

• Mineral A is softer than Mineral B

When are igneous rocks formed?

• when layers of mud form inside Earth

• when layers of mud are compressed

• when melted rock solidifies

• when solid rock melts

The picture shows a piece of slate. Slate is a type of rock that forms when shale rock is exposed to heat and pressure deep under Earth's surface for thousands of years.

What type of rock is slate?

• igneous

• intrusive

• metamorphic

• sedimentary

Granite cools very slowly from molten rock and therefore has very large crystals that are visible with the naked eye. Using this information, what is granite?

• an igneous rock

• an extrusive rock

• a sedimentary rock

• a metamorphic rock

Ryan finds a rock that has large crystals inside. What can Ryan most likely determine about the rock he found?

• The rock was heated very slowly.

• The rock was weathered very quickly.

• The rock was cooled very slowly.

• The rock was deposited very quickly.

Over time, small pieces of rock may be brought together by water. When the water evaporates, the Sun will harden these rocks into a single layer of

• metamorphic rock

• sedimentary rock

• obsidian rock

• igneous rock

Which explanation describes how metamorphic rocks are formed?

• Metamorphic rock is formed when sedimentary and igneous rocks change over time under heat and pressure.

• Metamorphic rock is formed when earthquakes shake up the rocks so they are broken into small pieces.

• Metamorphic rock is formed when sedimentary rocks are broken down over time by wind and rain.

• Metamorphic rock is formed when lava that erupts from a volcano cools in the atmosphere.

Which of these is most likely made of pieces of rock that are weathered by water and wind?

• diamonds

• sand

• grass

• vegetables

The picture shows the Grand Canyon.

Which statement best explains how this canyon formed over millions of years?

• Wind deposited sand and silt that formed the steep mountains.

• Rivers carried sand along the banks and formed steep plateaus.

• Rain fell in the area and caused the sides of the hills to fall down.

• Water and flowing rivers wore away the sides of raised landforms.
