Second Science Test Review Topic 3B Rocks/Erosion/Resources

Sam finds a rock near a volcano. He knows that the rock has formed after the magma cooled. How can this rock be described?

• Fossilized

• Igneous

• Metamorphic

• Sedimentary

Ms. Rod found a rock on her last summer trip. She noticed it had thin wavy layers. How was this rock formed?

• it is a sedimentary rock that was formed by heat and pressure

• it is a metamorphic rock that was formed by heat and pressure

• it is an igneous rock that was formed when lava cools

• it is a sedimentary rock that was formed by cementing together and forming layers

A student has two mineral samples. They are both shiny like fools gold. Which property might the student use to help distinguish between the two minerals?

• color

• mass

• streak

• volume

The students in Ms. Rod's class were classifying minerals according to their properties. Ralph was being naughty and dropped one of the mineral samples. He noticed that the mineral's crystals broke into pieces with smooth, flat surfaces. What mineral property was Ralph looking at?

• cleavage

• hardness

• luster

• streak

Phosphate is mined in Florida. It is a non-renewable resource. Which of these identifies the main use of phosphate?

• to punish Ralph for dropping the mineral

• to feed animals

• to make toothpaste

• to fertilize plants

Florida has many natural resources. Which resource is naturally abundant in Florida and is most useful to produce energy?

• sunshine

• phrosphate

• limestone

• wind

Ms. Rod predicts that Tamayo is going to be an engineer in the electronic industry. He will make a revolutionary cell phone that tops Apple's I-phone. Which resource is naturally abundant in Florida and is most useful to Tamayo in his new invention?

• silicon

• phosphate

• ocean water

• limestone rock

Which is an example of erosion?

• roots of a tree growing through the sidewalk

• rocks in a trail breaking

• wind carrying small particles of sand at the beach

• rocks breaking because people are walking on them

A bright and amazing student in Ms. Rod's science class created a hydro-electric generator. The water moves a turbine, creating electrical energy by the use of hydro-power. Why is hydro-power a renewable resource?

• the environment can be helped by using hydro-power to generate electricity.

• hydro electricity can be stored in a hydro-power plant

• hydro power uses water, which is a natural resource

• hydro power uses water which is part of the water cycle and can be used up
