Switch from growing corn to growing soybeans.
Install a windmill that pumps water for irrigation.
Install battery-powered machines to milk the cows.
These resources listed in the chart are renewable energy
resources.
Which resource fits BEST with those listed?
coal
natural gas
crude oil
wind
The United States uses various energy resources, including oil, coal, and natural gas. Which of these is the best possible solution to extend the availability of these energy resources in the future?
Taking more resources where they can be found.
Developing larger commuter vehicles for transportation.
Developing vehicles that use renewable sources of energy.
Taking energy resources away from homes and office buildings.
Jim's teacher asked the class if they noticed the weathering that was taking place on the sidewalk outside the school
door. When Jim left school that day, he looked at the
sidewalk and saw what his teacher meant. What did Jim see on the sidewalk caused by weathering?
the building's shadow
the leaves from a tree
dirt scattered by the wind
cracks from nearby tree roots
The rock cycle explains the change of one form of rock into another. Look at the diagram of the rock cycle.
When does the rock cycle come to an end?
The cycle ends when sedimentary rock forms.
The cycle continues and never comes to an end.
The cycle ends when weathering grinds down rock.
The cycle is not a constant process, but only takes place occasionally.
Which of these types of rocks form as a result of a very large amount of heat and pressure?
igneous rock
sedimentary rock
metamorphic rock
lava rock
Weathering and erosion play a major role in changing Earth's surface. They also have different roles in the rock cycle. Which statement is correct in describing the difference between weathering and erosion?
Weathering breaks down rocks, and erosion moves sediment.
Erosion breaks down rocks, and weathering moves sediment.
Weathering is the transportation of water, wind, or ice, and erosion is the separation of rocks.
Erosion is the transportation of water, wind, or ice, and weathering is the layering of material that builds rock layers.
While playing on the playground, McPherson finds an interesting looking rock. When he looks closer, he notices that there are several small shells in the rock. Which type of rock did McPherson find?
Igneous
metamorphic
sedimentary
granite
Max is examining rocks to determine their type. He looks at a rock and decides it is an igneous rock. Which rock is Max most likely examining?
a smooth, white rock that easily crumbles
a dark, shiny rock that formed quickly from lava
a soft, light colored rock that contains many shells
a black, smooth rock that can be burned for energy
A teacher shows her class a mineral called serpentine. She says the mineral is greasy or shiny, but not like glass. Which property of the mineral is the teacher describing?
cleavage
color
hardness
luster
A scientist finds a rock sample and wants to test its cleavage. Which action should the scientist do to test the cleavage?
Look closely at the sample to see if it reflects light.
Break the rock to see what shape the pieces make.
Scratch it with his fingernail to see if he can
make a mark.
Scrape the rock against a hard surface to see what color it makes.
Which action is an example of physical weathering?
Rain washes soil down a hill.
Wind blows sand across a desert.
Pieces of soil and rocks are carried down a stream.
Water freezes between bricks and causes them to crack.
Sheila is classifying the rocks in her collection. She knows that limestone often contains fossils. In which category of rock should she classify these rocks?
igneous
granite
metamorphic
sedimentary
Mount St. Helens, located in southwest Washington State, erupted on May 18th, 1980. The lava from this eruption had temperatures near 660 °F. What category of rock is formed when the lava quickly cools?
conglomerate
igneous
metamorphic
sedimentary
Both igneous rock and sedimentary rock can turn into metamorphic rock. What two conditions are necessary for this to happen?
heat and erosion
heat and pressure
weathering and erosion
weathering and pressure
Derrick is examining a piece of obsidian with a hand lens. He knows that igneous rock has many properties. Which is a property of igneous rock?
It is always very soft.
It is always formed when molten rock cools.
It is made of crushed animal shells, bone, and teeth.
It forms when heat and pressure change other rocks.
Paolo wanted to identify a mineral. He rubbed a corner of the mineral across a white tile and recorded the color of the mark. What property was Paolo measuring?
cleavage
color
luster
streak
The Mohs’ scale lists diamond as the hardest mineral. What does this mean?
Diamonds can scratch any other material.
Diamonds weigh more for a given size than any other mineral.
Diamond is the only mineral that does not leave a streak on a tile plate.
Diamond is the only mineral that will not break when hit with a hammer.
Minerals can be formed in different ways. What is one way that minerals form?
through the weathering of rocks
through the crystallization of magma
through processing in chemical factories
through the action of bacteria on decaying matter
