climate is determined by patterns in weather conditions over time.

Which of these locations would it NOT be helpful to use the law of superposition to date a rock formation?

Which of the following statements best explains why a rock layer with fossils cannot be igneous rock?

The melting process would have destroyed the fossil.

Which of the following describes a difference between these folding and faulting?

Folding = bending of rock layers. Faulting = fracturing of the rock

Some areas of the beach might shrink while other areas grow. Which statement best explains the cause of these changes?

Shrinking areas are due to erosion. Growing areas are due to deposition

Why is the greenhouse effect important to life on Earth?

The greenhouse effect helps Earth’s atmosphere hold in heat.

Which statement describes the connection between plate tectonics and the rock cycle?

As plates move, pieces are broken off & form the basis of sedimentary rocks

Which of the following correctly identifies the type of plate boundary and the resulting action shown at B?

A convergent boundary = creation of a volcano.

Which of the following examples best describes an effect of urbanization?

Motor vehicle emissions increase smog in the air that can block radiation

Which of these statements best describes why the Atlantic Ocean is slowly expanding?

Convection brings magma up to the surface building new sea floor.

Which characteristic of the outer core makes it unique among the other layers of Earth?

The outer core is the only liquid layer & creates Earth’s magnetic field.

What conclusion could scientists make about why there are similar fossils of organisms on different continents?

Earth’s surface must have changed over time due to tectonic movement.

Winds blow towards the Equator from the Northern & Southern Hemispheres. How could these winds influence the weather?

Winds blow cooler, gentler winds toward the equator.

What is the source of energy that drives Earth’s tectonic movement, formation of earthquakes, & volcanic eruptions?

heat energy from Earth’s molten layers

Which of the following best explains how minerals get into streams?

Rain dissolves minerals in rocks and soil along the stream during runoff

Questions 20

Answers

1
Air currents form due to the uneven heating of Earth. What direction will the air currents most likely move in the pic?
from the water toward the land
straight down over the land
from the land toward the water
straight up above the water
2
Sandbars are shallow areas of ocean where sand builds up. Which factor causes sandbars to form or change shape?
the motion of glaciers
the motion of wind and waves
the motion of Earth’s mantle and crust
the motion of large boats
3
Which of the following statements explains why the amount of water in our environment has remained relatively constant.
Water continually flows from the center of Earth.
Vast quantities of water are created by lightning in clouds.
Organisms combine hydrogen and oxygen to make their own water.
Organisms return water to the environment after they use it.
4
Which phrase best distinguishes the difference between weather and climate?
it has been raining a lot in Florida lately, changing the climate
weather for Florida is typically tropical and wet.
the climate of an environment is changing constantly
climate is determined by patterns in weather conditions over time.
5
Which of these locations would it NOT be helpful to use the law of superposition to date a rock formation?
Walls above a canyon river b/c erosion would have worn away the layers
Limestone wall since chemical weathering would change the sediment layers
An ocean cliff because the ocean current would make the layers hard to see
A mountain formed by the up-thrust of magma cutting through rock layers
6
Which of the following statements best explains why a rock layer with fossils cannot be igneous rock?
Weathering and erosion would have broken up the fossil
The melting process would have destroyed the fossil.
The rock was found at an inland location away from heat and pressure.
Volcanic eruptions would have buried the fossil too deeply to be found.
7
Which of the following describes a difference between these folding and faulting?
Folding = surface forces. Faulting = subsurface forces
Folding = caused by circular plate movement. Faulting = from pressure/heat
Folding = fracturing of the rock. Faulting = bending of rock layers
Folding = bending of rock layers. Faulting = fracturing of the rock
8
Some areas of the beach might shrink while other areas grow. Which statement best explains the cause of these changes?
Shrinking areas are due to erosion. Growing areas are due to deposition
Both processes are due to erosion.
Shrinking areas are due to deposition. Growing areas are due to erosion
Both processes are due to deposition.
9
Why is the greenhouse effect important to life on Earth?
The greenhouse effect reflects harmful radiation into the upper atmosphere.
The greenhouse effect absorbs x-rays in the winter time.
The greenhouse effect makes it much colder at the North and South poles.
The greenhouse effect helps Earth’s atmosphere hold in heat.
10
What type of lake is caused by the collapse of these limestone caves?
an artificial lake
an oxbow lake
a sinkhole lake
a glacial lake
11
Which statement describes the connection between plate tectonics and the rock cycle?
Tectonic plate movement creates more magma & develops sedimentary rock
As plates move, pieces are broken off & form the basis of sedimentary rocks
Sediments are moved out to sea and deposited as igneous rock.
Uplifting metamorphic rocks causes the plates to move slower b/c conduction
12
Which of the following correctly identifies the type of plate boundary and the resulting action shown at B?
A transform boundary = formation of a continental rift zone
A convergent boundary = develops new land.
A convergent boundary = creation of a volcano.
A transform boundary = form volcanoes.
13
Which of the following examples best describes an effect of urbanization?
Motor vehicle emissions increase smog in the air that can block radiation
Wildlife diversity increases due to more open spaces within the city.
More land is available in large cities to grow crops.
More people in large cities reduces overall waste production on Earth.
14
Which of these statements best describes why the Atlantic Ocean is slowly expanding?
North America and Europe collide, causing volcanic activity and earthquakes
The crustal plates of North America and Europe sink as they get older
Conduction from the mantle makes the crustal plates larger
Convection brings magma up to the surface building new sea floor.
15
Which characteristic of the outer core makes it unique among the other layers of Earth?
The outer core is the densest, making it more rigid than the other layers
The outer core moves in convection currents.
The outer core is the hottest of all the layers and is solid.
The outer core is the only liquid layer & creates Earth’s magnetic field.
16
Which of the following events is most directly caused by radiation from the Sun?
the circulation of air
the movement within Earth’s mantle
the movement of ocean currents
the warming of Earth’s surface
17
What conclusion could scientists make about why there are similar fossils of organisms on different continents?
Early maps were wrong & continents are where they have always been.
Plants and animals must have come over on the ships used for exploration.
Continents have similar organisms b/c they have adapted to their habitats
Earth’s surface must have changed over time due to tectonic movement.
18
Winds blow towards the Equator from the Northern & Southern Hemispheres. How could these winds influence the weather?
Winds blow drier, more constant winds toward the equator.
Winds blow colder, heavier winds toward the equator.
Winds blow warmer, more unpredictable winds toward the equator.
Winds blow cooler, gentler winds toward the equator.
19
What is the source of energy that drives Earth’s tectonic movement, formation of earthquakes, & volcanic eruptions?
magnetic energy from Earth’s magnetic field
heat energy from Earth’s molten layers
tidal energy from Earth’s oceans
light energy from the Sun that reaches Earth’s surface
20
Which of the following best explains how minerals get into streams?
Minerals evaporate with water & gets deposited into streams.
Rain dissolves minerals in rocks and soil along the stream during runoff
Rain in minerals from the atmosphere falls into the stream.
The stream absorbs minerals from plants growing around the area
