What are the three VISIBLE properties geologists use to identify rocks and minerals?

• Color - What color is it?

• Luster - How does it behave under light?

• Hardness - Can it be scratched or does it scratch other rocks?

• Texture - How does it feel?

What test determines a rock's hardness?

• Scratch Test

• Density Test

• Streak Test

Answer explanation

Softer rocks can be scratched while harder rocks can scratch other rocks.

What test determines the true color of the minerals in a rock?

• Scratch test

• Density test
• Streak test

Answer explanation

To test the streak of a rock, rub it along the rough side of a piece of tile and you will see what true color are in the minerals of your rock!

Geologists have classified rocks into three main categories. Match these rocks to their definitions.

• Sedimentary Rock

• Rocks formed from sediment that has been hardened in a cementing process

• Metamorphic Rock

• Igneous or sedimentary rock that seems to have been changed by heat or pressure

• Igneous Rocks

• Rocks that can be formed from hot magma or lava

Answer explanation

Much sedimentary rock is formed in the sea, and yet we find sedimentary rock on almost 75% of continental land.

*Igneous Rocks: Pumice, obsidian, and granite

*Sedimentary Rocks: Sandstone, Limestone, Shale

*Metamorphic Rocks: Marble and Slate

A ​ (a)   is a term evolutionists use to describe a "missing link" between two kinds of animals to show how one kind of animal could have turned into another kind of animal.

• transitional form
• evolutionary form
• intermediate form
