The Changing Earth (SOL 3.7, 3.10)
1
Freezing and melting water causes rocks to break slowly into small pieces and thus forms:
carbons
soil
fossils
rocks
2
Materials from the soil that plants need to grow are:
clays
sediments
nutrients
sand
3
Soil that is a mixture of clay, sand, and humus is called:
clay soil
sandy soil
loam
moss
4
What kind of soil has few nutrients?
loam
sandy soil
humus
top soil
5
Decayed matter that becomes part of the soil is called:
sand
sediments
clay
humus
6
Materials that are used over and over again are:
wasted
recycled
decayed
manufactured
7
Changing the kinds of plants grown in the soil every few years replaces lost:
nutrients
ores
sand
clay
8
The layer of the earth made of rocks and soil is called the:
mantle
crust
core
shell
9
The natural wearing-down or breaking-apart of rocks is called:
weathering
mining
erupting
grinding
10
A shaking or sliding of the earth's crust is
erosion
an earthquake
weathering
mining
11
How do scientists study the mantle and core of the earth?
by digging
by going inside the earth
with special instruments
by explosives
12
When the earth's crust is changed because soil is moved by wind, this is
weathering
wind erosion
an eruption
layering
13
Plants can help change the earth's
core
magma
crust
shape
14
A mountain with an opening where lava, ash, rocks, and other materials come out is
magma
mantle
volcano
core
15
The earth's crust is usually changed very slowly by
earthquakes
storms
erosion and weathering
volcanoes
