Chapter 6 Environmental Earth Science Test

A forest that is located about _________ north latitude would have fallen leaves on the forest floor during the fall.

40 degrees NORTH (N)

During harsh winters, animals of the __________ have daptations such as the ability to change color to avoid predators.

Taiga (S)

You are walking through a forest that gets large amounts of rain, has high humidity, and had moderate temperatures year round. Where might you be located?

The Pacific Northwest

Grasslands, such as the prairies of North America

are threatened by soil erosion because native grasses have been damaged or destroyed by plowing and overgrazing.

Biomes:

are usually described by their vegetation

Animals that live in the desert

are usually nocturnal

Adaptations of desert animals that help them survive in the hot, dry desert often include

searching for food at night

Chaparral plants usually survive fires because

they can resprout from small amounts of surviving plant tissue

A forest with the greatest species diversity would be located near the __________.

equator (G)

The distance north or south of the equator, as measured in degrees, is called

latitude

All of the following are characteristics of temperate rain forests EXCEPT

low rainfall in summer but abundant snow in winter

Biomes found up to 30 degrees north and south of the equator are often ____________.

rainforest (P)

Prairie (M)

#45

R

Which of the following adaptations are used by animals of the Arctic tundra?

Rodents burrow underground for winter protection

Which of the following is an adaptation of coniferous trees in the taiga?

They have leaves that retain water, due to their shape and waxy coating

Which of the following is NOT correct?

Tropical rain forests are resistant to change because the plants contain so many nutrients.

Due to the extreme temperature conditions and simple, easily disrupted food chains, the __________ is very sensitive to human disturbance.

Tundra (A)

Taiga is

a forest biome dominated by coniferous trees, such as pine, fur, and spruce.

If you visited a savanna, you would likely see

a large herds of grazing animals such as rhinos, zebras, and gazelles

Which of the following is NOT true about temperate deciduous forests?

all of the above

Which of the following is located primarily in coastal areas that have Mediterranean-style climates with warm, dry summers and mild, wet winters?

chaparral

Most __________ plants are low-lying evergreen shrubs and trees with small, leathery leaves.

chaparral (O)

Tropical rain forests are threatened by

deforestation and the trade of rain forest plants and animals.

A(N) _________ biome has an annual rainfall of less than 25 cm

desert (Q)

Which of the following would you expect to see in the emergent layer of a tropical rain forest?

eagles, bats, and snakes

The deforestation of the rain forests may cause climate changes which, in turn, may affect

flooding

The Tundra

has a layer of soil that is permanently frozen beneath the top soil.

In the tundra, the frozen layer of soil just beneath the surface is called the _________.

permafrost (D)

Biomes with higher temperatures and less precipitation tend to have

shorter and less dense vegetation

Which of the following best describes a tropical rain forest?

species of animals with specialized ways of surviving in order to avoid competition

As you travel from the North Pole toward the equator, you would expect to see
