Water seeps into a tiny crack in a rock. The water freezes and expands, pushing against the sides of the crack. The rock breaks apart. What is this an example of?
abrasion
decay
erosion
weathering
Which of the following is an example of erosion?
Chemicals in water weaken rock causing it to break into pieces.
A river carries bits of rock and soil away from the riverbanks to the ocean.
A plant's roots grow into the tiny cracks in a rock, causing it to break apart.
Ice in a crack in a rock thaws and seeps deeper into the rock. When the water freezes, it expands and widens the crack.
During the 1930s, farmers plowed up prairie grasses on the Great Plains. The soil dried out. Later, wind blew the soil away because the grass was not there to hold it.
What do scientists call the process of the wind carrying the soil away?
decay
erosion
tornado
weathering
Natural processes affect rocks and soil. The land is always changing.
What is the main difference between weathering and erosion?
Weathering can involve ice, but erosion does not.
Weathering involves weather, but erosion does not.
Weathering only involves wind, while erosion only involves water.
Weathering happens in one place, while erosion involves the movement of material.
Which of these best describes the result from weathering by a fast-moving river?
smooth, rounded rocks
rocks with jagged edges
sand moved further downstream
large rocks carried from different places
Mr. Li told his science class that the slate table-tops in the classroom were made from rocks that had been under very high temperature and pressure. Into which category of rock can slate be placed?
igneous
metamorphic
sedimentary
volcanic
Joe found a beautiful rock while hiking. He didn't know what kind of rock it was, but he knew a test that could help him find out. He took a small ceramic tile out of his backpack and scraped the rock across it. Why did Joe do that?
He wanted to make the rock have a shiny luster.
He wanted to test the hardness of the rock.
He wanted to break the rock so that he could check the cleavage pattern.
He wanted to see the color of the line that the rock would make on the tile.
Some renewable resources must be carefully managed to be sure that there will be enough for people to use. Which of the following is the best example of a renewable resource that humans can never use up?
trees
sunlight
oil
natural gas
Florida can generate power for fuel and electricity from many of its natural resources. Which plentiful Florida natural resource could be used for generating power?
coal
phosphate
river water
sunlight
Mr. Misner likes to identify rock samples using several common tests. The tests tell him about the characteristics of the rock. Which of these characteristics is NOT one that Mr. Misner would commonly use to identify rocks?
how a rock breaks apart
how a rock scratches other minerals
how shiny the surface of the rock is
how a small electric current goes through the rock
Florida has many nonrenewable resources. Which of these resources are nonrenewable?
coal
solar energy
trees
wind
Kim collects fossils. She has fossils of trilobites and ferns as shown. In which kind of rock are the fossil remains of plants and animals most likely to be found?
igneous
metamorphic
mineral
sedimentary
Humans need to use resources found on Earth. One way to classify these resources is whether they are "renewable" or "nonrenewable." Which is true of all nonrenewable natural
resources?
They are used for energy.
They need to be created by time, heat, and pressure.
They can only be used once and cannot be reused or recycled.
They cannot be replaced quickly enough once they are used up.
