6th EMBRACE Unit 5

A hurricane becomes more powerful by evaporating water from

• lakes

• mountains

• oceans

• rivers

Warm air rises at the equator and cold air sinks at the poles creating

• tornadoes

• tornadoes

• convection currents

• the Coriolis effect.

What causes land breeze and sea breeze?

• The differential heating of land and sea by the Sun results in the movement of air.

• Hot air from the sea blows over the land because there is a high pressure area over the sea.

• Cold air blows from the land over the sea because there is a low pressure area over land.

• Air blows from land over the sea because of the rotation of Earth on its axis.

All weather activity occurs in which layer of the atmosphere

• troposphere

• stratosphere

• mesosphere

• thermosphere

The rate of evaporation depends on four main factors – water body size, heat energy, atmospheric pressure and air movement. Air movement moving across the top of the water can physically lift water droplets from the surface, increasing evaporation. Based on this information, you would expect what weather event to cause an increase in evaporation over tropical seas?

• hurricane

• monsoon

• tornado

• tsunami

What type of heat transfer is used to fry an egg in a pan and how can you tell?

• It is conduction because the egg does not cook.

• It is conduction because the egg is touching the pan.

• It is convection because you put oil in a frying pan to cook in it.

• It is convection because you can feel the heat a few inches away from the pan.

A tornado's vortex will form when

• heavy rain forms.

• two different fronts meet.

• two different air masses meet.

• when warm moist air rises over water.

Winds curve as they blow due to

• gravitational attraction.

• the rotation of the earth.

• lack of pressure difference between regions.

• being blocked by winds from the opposite direction.

According to the weather map seen here, we could expect weather conditions in Memphis to include

• warmer temperatures, clearing.

• cold temperatures, precipitation.

• warm temperatures, very cloudy, and heavy rain.

• warm temperatures, increasing clouds, and showers.

During the summer months, the sun warms tropical ocean waters and a large amount of water evaporates into the air. Which of these weather events will MOST LIKELY will occur?

• blizzard

• hurricane

• tornado

• tsunami
