How do ocean currents influence the formation of hurricanes?

• By cooling the ocean surface

• By providing warm water that fuels the storm

• By creating high-pressure systems

• By increasing salinity levels

Describe how air masses interact with ocean currents to affect weather patterns.

• Air masses cool down ocean currents, leading to storms.

• Ocean currents warm air masses, influencing storm development.

• Air masses and ocean currents do not interact.

• Ocean currents block air masses from moving.

What is the role of the Coriolis effect in global atmospheric movement?

• It causes air to move in a straight line.

• It deflects moving air to the right in the Northern Hemisphere.

• It has no effect on atmospheric movement.

• It causes air to move faster at the equator.

Identify the global wind pattern that influences weather in the United States.

• Trade winds

• Polar easterlies

• Westerlies

• Doldrums

TEKS.SCI.8.10B

Explain how the jet stream affects local weather conditions.

• It brings warm air from the equator.

• It can lead to sudden changes in temperature and precipitation.

• It has no impact on local weather.

• It only affects weather at the poles.

How do global patterns of atmospheric movement influence the development of cyclones?

• They prevent cyclones from forming.

• They steer cyclones along certain paths.

• They have no influence on cyclones.

• They cause cyclones to dissipate quickly.

What is biodiversity?

• The variety of life in a particular ecosystem

• The number of species in a food web

• The amount of energy in an ecosystem

• The size of an ecosystem

Tags

TEKS.SCI.8.12C

How does biodiversity contribute to the stability of an ecosystem?

• By reducing the number of species

• By increasing competition for resources

• By providing a variety of organisms that can adapt to changes

• By decreasing the energy flow
