Unit 1 Review: TEKS 8.10

Front

What is a convection current?

Back

A convection current is a circular movement of fluid (liquid or gas) caused by the uneven heating of the fluid, which creates areas of different temperatures and densities.

Front

How do hurricanes form?

Back

Hurricanes form over warm ocean waters, typically near the equator, where the heat and moisture from the water fuel the storm.

Front

What is the initial movement direction of hurricanes formed at the equator?

Back

Hurricanes formed at the equator initially move west.

Front

What does 'El Niño' refer to?

Back

El Niño refers to a warming of the ocean surface in the central and eastern tropical Pacific Ocean, which can affect global weather patterns.

Front

What is the primary energy source for hurricanes?

Back

The primary energy source for hurricanes is warm ocean water.

Front

How do ocean currents influence weather patterns?

Back

Ocean currents influence weather patterns by distributing heat from the equator to the poles, affecting climate and weather conditions.

Front

What is the role of warm ocean water in hurricane formation?

Back

Warm ocean water provides the heat and moisture necessary for the development and intensification of hurricanes.

Front

What are the effects of El Niño on global weather?

Back

El Niño can lead to increased rainfall in some regions and droughts in others, disrupting normal weather patterns.

Front

What is the difference between convection currents and ocean currents?

Back

Convection currents are movements within fluids caused by temperature differences, while ocean currents are large-scale flows of seawater driven by wind, temperature, and salinity differences.

Front

What are the characteristics of a hurricane?

Back

Hurricanes are characterized by strong winds, heavy rain, and a low-pressure center called the eye.
