Fill in the sentences below to explore the process by which a storm becomes a hurricane. Some terms may be usedmore than once.

A disorganized array of clouds and thunderstorms with little or no rotation is known as a tropical disturbance. In a tropical depression, wind speeds are below 38 miles per hour. . If winds are between 38 and 74 miles per hour, the condition is called a tropical storm. In order to be considered a hurricane, wind speeds must be in excess of 74 miles per hour. The storm is given a name once it reaches the tropical storm stage. Half or more of tropical storm(s) eventually become hurricanes.

ALL EXCEPT The doldrums are the wind boundary between the trade winds

Of the following physical properties of the atmosphere, which is/are true?

Air always moves from high-pressure regions toward low-pressure regions. The air temperature is warmer near Earth's surface than in the upper part of the troposphere. Low pressure at the surface is associated with rising air (movement away from the surface Warm air holds more water vapor than cool air.

At what latitude(s) on Earth is the speed of rotation the greatest?

IN ORDER 0 degrees fictitious Part C - In the Southern Hemisphere, the Coriolis effect causes an object to be deflected to the left of its intended direction. In the Northern Hemisphere, the Coriolis effect causes an object to be deflected to the right of its intended direction. Part D - counterclockwise Part E - WRONG**

The Trade Winds are one type of prevailing wind pattern. How many other types of prevailing winds are there among earth's global wind patterns?

IN ORDER 2 Equatorial regions receive more direct sunlight than other areas This air is cool and dry. the Coriolis effect Cooled air moves north toward the equator and is deflected toward the west by the Coriolis effect. Wind near the north pole would move to the northeast, and the wind near the south pole would move to the southeast. south in the Southern Hemisphere and north in the Northern Hemisphere

As discussed in the video, air always moves from _____ atmospheric pressure regions to _____ atmospheric pressure regions.

IN order high; low a balloon The higher pressure inside the item forces the air out into the lower pressure of the room.

Part C - Hurricane Fran Hurricane storms are ranked on the Saffir-Simpson scale, where a category 5 rating is the most severe and category 1 is the least severe. Examples of category 5 hurricanes in the United States include Andrew, Camille, Katrina, Rita, Felix, and the "Labor Day" hurricane.

ON WHICH DAY AT 7am - press gradient was higher sept 5 at 7am how far in miles did eye travel - aprox 400 miles what was the rate of travel in 24 time span - 17 miles per hour

Of the following statements about the transfer of heat on Earth, which is/are true?

Ocean currents move warm water from the tropics to higher latitudes. Water vapor in the air carries latent heat with it, which is released in other areas. Air currents move warmer air from the tropics to higher latitudes.

The strength of a hurricane is ranked from 1 to 5 on the

Saffir-Simpson Scale.

Which of the following statements about the Coriolis effect is correct

The magnitude of the Coriolis effect depends on how long the object is in motion

On what day(s) do all locations on Earth experience 12 hours of daylight and 12 hours of night?

WRONG

Part B - Hurricane damage Damage from hurricanes is primarily the result of three factors: Storm surge—The storm surge is a dome of water that sweeps ashore with the hurricane. The waves and water from the storm surge can cause incredible amounts of damage along coastlines.

WRONG

Which type of ice found in the marine environment does NOT form from freezing seawater

WRONG

WRONG**

Why is it colder in winter than in summer

When the Northern or Southern Hemisphere of Earth is tilted away from the sun it is winter because that part of Earth receives less direct energy from the sun.

In the figure above, which of the following statements correspond with direct sunlight over the Tropic of Capricorn? Choose all that apply.

Wrong***

The percentage of solar radiation reflected from the surface of Earth back into space is known as the

albedo

Which of the following locations has/have the potential to reliably harness wind power as a renewable energy source?

between 5 and 30 degrees latitude between 30 and 60 degrees latitude

Earth's polar regions (above 60° latitude) are classified as deserts because

cold, dry sinking air in the polar high regions produces little precipitation

Idealized pressure belts and wind systems are significantly modified by Earth's tilted axis of rotation and:

differences in the heat capacities of the ocean and land.

This diagram shows how seawater temperature varies with depth. Match the correct letter to the items indicated below.

greater.

What is a front?

in order the boundary between two air masses of different temperatures Rain occurs along and in front of a warm front Rain occurs along and behind a cold front. Rain near a cold front occurs over a smaller spatial area and is more intense than near a warm front. The type of front is determined by which air mass is moving Rising warm air cools, resulting in cloud formation and rain. Rising warm air cools, resulting in cloud formation and rain.

In coastal regions, sea breezes happen

in the afternoon; at night

In the figure above, which labeled location corresponds with direct sunlight over the equator?

location A location D

In the figure above, which labeled location marks the beginning of summer in the Northern Hemisphere?

location B

Earth's atmosphere is heated primarily by

re-radiation of solar energy from Earth's surface back into the atmosphere as infrared radiation

Air warmed by the land that rises and is replaced by cooler air from the ocean may produce a:

sea breeze.

The largest loss of life from a hurricane is usually due to:

storm surge.

The two factors that are most important in determining the density of air are:

temperature and water vapor content.

Hurricanes frequently make landfall on the U.S. Atlantic and Gulf coasts, but rarely, if ever, occur on the Pacific coast. The primary reason for the rarity of west coast hurricanes is that

the ocean water does not get warm enough to supply the needed heat energy for hurricanes

As a result of the Coriolis effect in the northern hemisphere, winds always are deflected:

to the right of their original direction

The temperate regions are characterized by:

westerly winds.
