Why is the greenhouse effect important to life on Earth?

The greenhouse effect helps Earth’s atmosphere hold in heat

What is the source of energy that drives Earth’s tectonic movement, the formation of earthquakes, and volcanoes?

heat energy from Earth’s molten layers

A shark fossil found hundreds of miles from the ocean at the base of a mountain cannot be in igneous rock because....

The melting process would have destroyed the fossil.

What conclusion could scientists after finding the same types of fossils on different continents?

The location of continents on Earth’s surface must have changed over time.

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

Rainwater dissolves minerals out of the rocks along the stream via runoff.

Why are some areas of the beach growing and some are shrinking?

shrinking due to erosion, growing due to deposition

Which of the following correctly describes folding?

Folding takes place when pressure and heat bend rock

Why is the ocean growing?

Convection within the mantle brings magma up to the crust, making sea floor

How do normal trade wind patterns change the weather of islands near the equator?

Trade winds blow cooler, gentler winds toward the islands

Why has the water in the environment stayed relatively constant?

Organisms return water to the environment after they use it.

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

Emissions from vehicles increase smog in the air that can block radiation

Where would the Law of Superposition not be helpful to date a rock formation?

on a mountain formed by the upthrust of magma in California

Which of the following events is MOST directly caused by radiation from the Sun?

the warming of Earth’s surface

Questions 20

Answers

1
During a convergent plate boundary, an oceanic plate will move under the continental plate creating a volcano.
True
False
2
Why is the greenhouse effect important to life on Earth?
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 reflects harmful radiation into the atmosphere.
The greenhouse effect helps Earth’s atmosphere hold in heat
3
During the day, air currents move in what direction?
from the water toward the land
from the land toward the water
straight up above the water
straight down over the land
4
What is the source of energy that drives Earth’s tectonic movement, the formation of earthquakes, and volcanoes?
light energy from the Sun that reaches Earth’s surface
tidal energy from Earth’s oceans
magnetic energy from Earth’s magnetic field
heat energy from Earth’s molten layers
5
A shark fossil found hundreds of miles from the ocean at the base of a mountain cannot be in igneous rock because....
The melting process would have destroyed the fossil.
The rock was found at an inland location away from heat and pressure.
Repeated volcanic eruptions would have buried the fossil too deep..
Weathering and erosion would have broken up the fossil
6
What conclusion could scientists after finding the same types of fossils on different continents?
Early mapmakers had the original locations of the continents wrong.
During early voyages, plants and animals must have come over on the ships.
Each continent has similar plants and animals because they have adapted.
The location of continents on Earth’s surface must have changed over time.
7
Which of the following best explains how minerals get into streams?
Rainwater that is high in minerals from the atmosphere falls into streams.
When water evaporates from the ocean, it takes minerals with it.
Rainwater dissolves minerals out of the rocks along the stream via runoff.
The stream absorbs minerals from the plants growing in and around its banks
8
Shoals (also known as sandbars) often change shape due to.......
the motion of Earth’s mantle and crust
the motion of glaciers
the motion of wind and waves
the motion of large boats
9
Why are some areas of the beach growing and some are shrinking?
only deposition
only erosion
growing due to erosion, shrinking due to deposition
shrinking due to erosion, growing due to deposition
10
Which of the following correctly describes folding?
Folding takes place when pressure and heat bend rock
Folding is caused by circular movement of the plates around each other
Folding begins with the fracturing of the rock
Folding is caused by forces of the plates found close to the surface
11
Why is the ocean growing?
As the crustal plates get older, they sink, causing the floor to spread
Convection within the mantle brings magma up to the crust, making sea floor
Conduction of heat from the mantle enlarges the crustal plates.
At the Mid-Atlantic Ridge, the plates collide, causing volcanoes
12
How do normal trade wind patterns change the weather of islands near the equator?
Trade winds blow colder, heavier winds toward the islands.
Trade winds blow drier, more constant winds toward the islands.
Trade winds blow cooler, gentler winds toward the islands
Trade winds blow warmer, more unpredictable winds toward the islands.
13
Why has the water in the environment stayed relatively constant?
Water continually flows from the center of Earth.
Organisms combine hydrogen and oxygen to make their own water
Vast quantities of water are created by lightning in clouds.
Organisms return water to the environment after they use it.
14
The inner core of Earth is made of liquid metal and is responsible for the Earth's magnetic field.
True
False
15
Which of the following examples best describes an effect of urbanization?
The greater concentration of people in cities reduces waste production
Emissions from vehicles 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.
16
The climate of an environment is determined by patterns in weather conditions over an extended period of time.
True
False
17
Where would the Law of Superposition not be helpful to date a rock formation?
on the walls of the Grand Canyon
on a wall of limestone in Florida
in a subsurface canyon off the coastline of Cuba
on a mountain formed by the upthrust of magma in California
18
As tectonic plates move, particles are broken off from the plates and form the basis of igneous rocks.
True
False
19
Which of the following events is MOST directly caused by radiation from the Sun?
the movement of ocean currents
the warming of Earth’s surface
the movement within Earth’s mantle
the circulation of air
20
What kind of lake forms when acid in groundwater dissolves limestone underground, forming a cave that fills with water?
sinkhole lake
glacial lake
artificial lake
oxbow lake
