Question 9

The image is a model showing the processes of the water cycle.

During an extreme rainy season, what can we expect to happen to the surface ground water stored in ponds and lakes?

Accepted Answer

water levels will increase because there is more precipitation

Answer

animals drink more water, so water levels decrease

Answer

water levels will increase because there is more evaporation and transpiration

Answer

water levels will decrease because there is more evaporation and transpiration

Question 10

Describe the role of temperature change in cloud formation.

Accepted Answer

Water on Earth heats up and evaporates into the atmosphere, then cools and condenses to form clouds.

Answer

As water on Earth cools down, it condenses in the air and forms clouds.

Answer

As water on Earth cools down, it evaporates into the atmosphere and forms clouds.

Answer

Water on Earth heats up and evaporates into the atmosphere. Water vapor continues to heat up to form clouds.

Question 11

Lori's class is completing an investigation about heat from the Sun. They placed a cup of water in a sunny spot in the grass outside of their classroom for one hour. They measured the temperature every 15 minutes and noticed that each time the water became hotter.

Where could the students place the cup to cool the water?

Accepted Answer

under a large tree

Question 12

Fronts are transition zones between cool and warm air masses. The leading edge of a wedge of cold air represents the frontal zone. The front is called a cold front if the wedge is moving into an area of warmer air. If the wedge is retreating, the front is called a warm front with warmer air moving into an area previously occupied by cool air. Which weather condition is NOT associated with cold fronts?

Accepted Answer

pressure rising steadily before passing and falling steadily after passing

Answer

sudden drop of temperature as front passes

Answer

strong thunderstorms along and ahead of the front

Answer

winds south-southwest before passing and west-northwest after passing

Question 13

Technological advances had helped reveal that the ocean floor was not flat, as once believed, but instead was marked by 50,000-kilometer-long, 3,000-meter-high ridges and 11-kilometer-deep trenches. How do scientists explain why, if new crust is constantly being formed from volcanic materials at the ridges, Earth's crust stays the same size?

Accepted Answer

Scientists found that the youngest oceanic crust is located nearest the mid-ocean ridge and divergent boundary and the oldest crust is at subduction zones where it sinks back into the Earth.

Answer

Seafloor spreading is the cause of new crust being added. Old crust crumbles and forms mountains throughout the Earth's surface. Mountains keep growing.

Answer

Scientists hypothesize that new crust is the result of volcanic activity throughout the Earth's surface and older magma is destroyed as it subducts during earthquakes into Earth's mantle.

Answer

Scientists found that the oldest oceanic crust is located nearest the mid-ocean ridge and forms from volcanic activity; the youngest crust is nearest the trenches and it comes from magma flowing up to Earth's surface.

Question 14

Like animals, plants undergo cellular respiration to produce energy. Plants use carbon dioxide and release oxygen and water. Water returns to the atmosphere and becomes part of the water cycle through the process of

Accepted Answer

transpiration.

Answer

condensation.

Answer

Answer

precipitation.

Question 15

Accepted Answer

the tidal range

Answer

a lunar day

Answer

flood and ebb

Answer

the tidal current

Question 16

The action of warm air rising and cold air sinking plays a key role in the formation of severe thunderstorms. If thewarm surface air is forced to rise, it will continue to rise, because it is less dense than the surrounding air. Inaddition, it will transfer heat from the land surface to upper levels of the atmosphere through the process of

Accepted Answer

convection

Answer

conduction

Answer

thermal expansion

Answer

radiation

Answer

upwelling

Question 17

Check out the map showing tornado alley in the U.S. During the winter of 2017, massive tornadoes occurred in the states of Alabama and Georgia, two states that ARE NOT in tornado alley. If the conditions for a tornado are predictable, how could these tornadoes have formed in these two states?

Accepted Answer

Warm, moist Gulf coast air meets cold, dry continental air moving down from Canada

Answer

Warm, moist Pacific coast air meets cold, Atlantic coast air

Answer

Arctic, Canadian air meets west moving air from the cold Atlantic coast

Answer

A northeastern air mass drops down into the southern states bringing precipitation

Question 18

Meteorologists are able to predict weather within probable ranges because air masses responsible for weather interact in predictable ways. The boundary at which two air masses meet is called a front, which is the main cause of stormy weather. This weather map shows conditions for severe weather. Which statement best elaborates on how air masses would interact to cause severe weather?

Accepted Answer

Cold air is denser than warm air, so the cold air mass travels beneath the warm air, pushing it up. Storms are often the result of rising warm air.

Answer

Warm air masses and cold air masses have different densities, and when they mix, their densities stabilize, and excess moisture is released.

Answer

As the fronts move away from one another, the cold air mass is heated by the warm air mass. When cool air becomes warm, precipitation falls.

Answer

Since warm air is more dense than cold air, the cold air mass is forced higher. When the cold air becomes too heavy, it releases heavy precipitation.

Question 19

This table shows sizes of Earth's oceans. Based on this table and the makeup of Earth's total water, which reasonable conclusion can be made?

Accepted Answer

Earth's largest source of salt water is the Pacific Ocean.

Answer

Answer

Earth's land has more surface area than Earth's oceans.

Answer

The Pacific Ocean is larger than all other oceans combined.

Question 20

A simplified model of atmospheric convection is shown here. Which of the statements explains how convection occurs to move energy around the Earth? Select ALL that apply.

Accepted Answer

The warmer air rises within the atmosphere.

Accepted Answer

Colder air in the atmosphere is denser and sinks down to the Earth.

Accepted Answer

The solar energy makes the surface of the Earth warmer than the atmosphere.

Answer

Colder air moves northward while warmer air moves southward.

Answer

Warmer air moves to the west while colder air moves to the east.

Question 21

The majority of Earth is covered with water, mostly oceans and the most important substance dissolved in the ocean is salt. Ocean salt comes from mineral deposits that find their way to the ocean through the water cycle. Salts comprise about 3.5% of the mass of ocean water. The salt concentration of ocean water depends on a specific location. When ocean water mixes with fresh water, like at the mouth of a river, the salinity will be lower. But where there is lots of evaporation and little circulation of water, salinity can be much higher. The Dead Sea, has 30% salinity and very few organisms can live in its very salty water. Based on the pie chart, we would expect most of the salt in oceans to be

Accepted Answer

sodium chloride.

Answer

sulfur chloride.

Answer

calcium chloride

Answer

magnesium chloride

Question 22

The pie chart shows the elements dissolved in the ocean to produce salt. But one element is missing. It is not a component of salt but it is a critical element for life to live in the oceans. What is that element?

Accepted Answer

oxygen

Answer

carbon

Answer

glucose

Answer

hydrogen

Question 23

Answer

near cool water.

Answer

Question 25

How would climate change impact the water cycle and the climate around bodies of water, like oceans and lakes?

Accepted Answer

Warmer temperatures would cause more evaporation and more precipitation.

Answer

Warmer temperatures would cause in a drier, hotter climate.

Answer

Warmer temperatures would cause more precipitation and less run-off.

Answer

Warmer temperatures would cause more evaporation and much less ground water.

Question 26

The rate of evaporation depends on four main factors: water body size, heat energy, atmospheric pressure and air movement. Warm waters and high winds often result in the development of hurricanes over the world's oceans because of increased evaporation. Where, on this map, is the LEAST likely location for a hurricane to form?
