1
What is the key difference between renewable (
R
) and non-renewable (
NR
) resources?
All NR resources pollute the environment; R resources don't
NR resources exist in limited amounts; R resources don't
NR resources must be refined before used by humans; R don't
NR resources exist in unlimited amounts; R resources don't
2
Why are faults sometimes referred to as "active plate boundaries?" Choose the best answer.
Because people should not live near to them
Because continental and oceanic plates are stuck together
Because they are volcanically active
Because the Earth's crust shifts on either side of them
3
What process hollows out limestone caves?
Mechanical weathering
Spacial weathering
Cave weathering
Chemical weathering
4
Which of the following is a true statement about recycling and resources?
Recycled products emit oxygen into the atmosphere
Recycling causes the Earth to cool down instead of warming
Recycling turns non-renewable resources into renewable ones
Recycling reuses resources instead of dumping into landfills
5
What impact does weathering have on soil formation?
Rocks are broken down into small pieces; then into sediment
Chemical weathering adds helpful chemicals to the soil
Volcanic eruptions contribute metamorphic rocks to the soil
Mechanical weathering adds ice to soil; then into water
6
Which of the following best describes the location of the mantle?
Between the crust and the core
Above the water
Between the here and there
Beneath the core
7
What is true of tectonic plates?
The plates don't move for centuries
There are fewer and fewer plates
Plates are constantly moving
Earthquakes cause the plates to move
8
What has to happen to sediment in order for it to become sedimentary rock?
It has to be buried deep within the Earth's layers
It has to be near a volcanic eruption
It has to be weathered by wind and rain
It has to bond and harden
9
What types of rocks are formed by weathering?
Sedimentary rocks
Igneous rocks
Metamorphic rocks
Volcanic rocks
10
How does recycling conserve natural resources?
It allows us to re-use products and manufacture new ones
It saves on the amount of fuel used by garbage trucks
It saves on the amount of plastic used to manufacture bags
It prevents garbage from being burned
11
What evidence did Alfred Wegener use to support his theory of continental drift?
The Himalayan Mountains
Fossil discoveries
Charts of seismic activity
Ancient maps of the world
12
What do granite and basalt have in common?
Rocks formed by weathering and erosion
Metamorphic rocks
Sedimentary rocks
Igneous rocks
13
How is mechanical weathering (
MW
) different from chemical weathering (
CW
)?
CW changes the chemical composition of materials; MW doesn't
CW occurs in a quicker time frame than MW
CW occurs in the mountains; MW occurs in flat landscapes
CW occurs in the tropics; MW occurs in temperate climates
14
Which of the following plate interactions is most likely to form a mountain range?
A subduction zone between continental and oceanic plates
A transform boundary between continental plates
A transform boundary between oceanic plates
A convergent boundary between continental plates
15
Which of the following is a metamorphic rock?
Quartzite
Basalt
Granite
Limestone
16
What can you infer from the fact that tectonic plates are always moving around?
The shape & location of continents have changed over time
Earthquakes will continue long after tsunamis have stopped
Tectonic activity probably caused the last ice age
New volcanoes form every few years
17
Which of the following is true of Earth's landmasses?
They are made of a single tectonic plate
They are the densest part of the crust
They are the upper part of the crust
They were formed by earthquakes
18
Which of the following is a true statement about tectonic plates?
They're located in the molten layer under the Earth's crust
All tectonic plates are located at the Earth's core
They're located approx. 10m below the surface of the ocean
All Earth's land masses rest on tectonic plates
19
How is natural gas (
NG
) different from coal(
C
)?
C is a form of petroleum; NG is emitted from volcanoes
NG is a fossil fuel; C is a renewable resource
NG is a renewable resource; coal is a fossil fuel
NG is a form of petroleum; C is extracted from coal deposits
20
Solar energy is considered a sustainable energy source. What does "sustainable" mean?
Capable of being continued long-term
Related to the sun
Related to light and heat
Available to everyone
