Volcanoes create new land on the Earth’s surface when -
lava flows cool and harden to form rock
an eruption destroys the side of a mountain
magma forms giant underground chambers
saltwater touches lava and changes into steam
Which of the following most likely caused the change to the Earth’s surface illustrated here?
Landslide
Thunderstorm
Tornado
Earthquake
Which of these most likely caused the rapid change to the Earth’s surface illustrated here?
Landslide
Volcanic eruption
Mountain building
Sandstorm
A landslide is most likely to be caused by -
Strong winds
Heavy rains
Breaking rocks
Cold weather
Scientists measured the elevation (how high the land is above sea level) of a certain area every year for four years. Which of the following best explains the change in elevation in this area?
Lava flows from a nearby volcano built up the land
Heavy rains in this area washed away much of the soil
Violent earthquakes opened up large cracks in the earth
Extreme hot weather made the ground very dry
A volcano can directly change Earth’s surface by
adding heat the the atmosphere
building up layers of hardened lava
releasing water vapor into the air
shooting out clouds of ash and smoke
Which of the following is one way an earthquake affects the Earth?
Large cracks suddenly form in the ground
A big rock slowly moves across the land
Hills of sand form as the wind blows
A large amount of heat rises into the air
A student gathered some rocks and soil to model the effects of a landslide. What is the best way to model how a landslide changes the Earth’s surface?
Pack the materials into a closed container and shake them rapidly.
Sift the materials through a strainer to separate the rocks and soil.
Place the materials on a sloping surface and pour water on them.
Spread the materials on a flat surface and blow them with a straw.
Which would be an example of a rapid change to the Earth’s surface?
A mountain forming due to volcanic eruptions.
A valley getting deeper as a river runs through it.
A plain forming cracks when hot weather makes it dry.
A hill rising as the wind piles up loose sand.
The picture shows an island in the middle of the ocean that increased in size in only a few weeks. Which of the following most likely caused this rapid change in the island?
Weathering of rocks
Movement of waves
Eruptions of a volcano
Piling up of sand
Cotton is useful for making clothing because it-
grows in soil
is food for insects
can be washed
has no color
Which of the following is a way that natural resources can be conserved?
Recycling aluminum cans
Making a new car
Burning down forests
Growing corn for food
Metals conduct heat very well. This makes metal good for making -
school buses
door knobs
soda cans
cooking pots
All of the following characteristics of wood make it a good resource to make furniture EXCEPT –
easy to get and inexpensive
burns at high temperatures
can be cut into shapes
relatively light in weight
Electrical wires need to be made out of material that is not expensive and conducts electricity. Which of the materials below should be used to make electrical wires?
Wood
Silk
Copper
Gold
Rocks near the ocean get broken into smaller pieces. What causes this change to these rocks?
Leaves falling from trees
Clouds forming in the sky
Water crashing against the rocks
Sal dissolving in the water
Which of the following processes will most likely contribute to the development of soil?
Volcanic eruptions that make new land
Building up of snow in very cold areas
Migration of animals to warmer climates
Breaking down of rock by wind, water, and ice
The organic matter in soil comes mostly from plants. Which of the following locations would most likely produce soil with the greatest amount of organic matter?
A desert with very high temperatures
A prairie with lots of grasses and flowers
A mountain with extremely cold winds
A river with quickly moving water
Soil is composed of all of these natural materials EXCEPT -
weathered rock
plant matter
plastic substances
animal remains
Students wanted to investigate soil formation by seeing how rocks are weathered. They shook rocks in a jar of water and measured their mass after every 20 shakes. Which of the following is a reasonable prediction for the mass of the rocks after 100 shakes?
166 g
157 g
141 g
100 g
