Unusually cold winters are problematic for Florida's manatees. Colder air temperatures lead to colder water, which lead to mantee illness and death. Fortunately, manatees can take shelter in warmer waters near natural springs and power plants. Which of the following accurately describes this chain of events leading to manatee illness?

• Changes in the atmosphere cause changes to the hydrosphere, which affects the biosphere

• Changes in the hydrosphere cause changes to the biosphere, which affect the atmosphere

• Changes in the geopshere cause changes to the hydrosphere, which affect the atmosphere

• Changes in the atmosphere affect the cryosphere, which affect the hydrosphere

Ships encounter currents and waves as they travel across the ocean. Surface currents and waves form when energy from the sun causes two of Earth's sphere to interact. Which two spheres interact to produce these waves and currents?

• The geosphere and biosphere

• The biosphere and hydrosphere

• The cryosphere and atmosphere

• The atmosphere and hydrosphere

Sometimes fires burn large areas of forests, which are part of the biosphere. Other than the biosphere, which of Earth's other spheres is a forest fire most likely to affect?

• geosphere

• cryosphere

• atmosphere

• hydrosphere

Which of these parts of the Earth system are interactive when Florida's orange trees grow?

• biosphere, hydrosphere, and atmosphere

• geosphere, cryosphere, atmosphere

• biosphere, hydrosphere, and cryosphere

• cryosphere, atmosphere, hydrosphere

Ozone is a molecule that is found mostly in the stratosphere. What is the main benefit of ozone?

• Ozone protects Earth from space debris

• Ozone protects Earth from lightning

• Ozone absorbs infrared radiation from the sun and shields Earth from some of this harmful energy

• Ozone absorbs ultraviolet radiation from the sun and shields Earth from some of this harmful energy

Earth's atmosphere traps energy from the sun. Which is a direct result of the trapping of energy by Earth's atmosphere?

• Earth has weather

• Earth has gravity

• Earth's atmosphere has four layers

• Earth has moderate temperatures

The atmosphere exerts a force (pressure) on Earth's surface. Why does the atmosphere exert pressure on Earth?

• because of the weight of air

• beacuse of the ozone layer

• because of energy from the sun

• because of the greenhouse effect

Differences in air pressure drive the global wind systems on Earth. Which term describes polar winds tha blow from east to west?

• easterlies

• jet streams

• trade winds

• westerlies

Winds can be characterized by their location and speed. Which winds are narrow bands of high-speed winds that blow in the upper atmosphere?

• the doldrums

• easaterlies

• jet streams

• westerlies

Different types of winds form in certain locations at different times of the day. Which breezes form during the day when land heats up faster than water?

• sea breezes

• land breezes

• valley breezes

• mountain breezes
