Label the clouds using the terms below.
alto-cumulus - Middle-level, medium-sized puffy clouds.
alto-stratus - Middle-level, layered clouds.
cirro-cumulus - High-altitude, small, wispy, patchy, puffy clouds.
cirro-stratus - High-altitude, thin, wispy clouds in layers.
cirrus - High-altitude, thin, wispy clouds.
cumulo-nimbus- Large, dense, towering clouds that cause thunderstorms.
cumulus - Low, puffy clouds.
fog - Ground-hugging clouds.
nimbo-stratus - Low, dark, rain cloud.
stratus - Low, layered, horizontal, wispy clouds with a flat base.
strato-cumulus - Low clouds, broad and flat on the bottom, puffy on top
(higher than cumulus and lower than altocumulus).
(Simple Version)
Label the clouds using the terms below.
cirrus - Thin, wispy, curly-shaped clouds.
cumulo-nimbus- Large, dense, towering clouds that cause rain and thunderstorms.
cumulus - Puffy clouds.
fog - Ground-hugging clouds.
stratus - Layered, horizontal clouds with a flat base.

Label the layers of the Earth's atmosphere using the terms below.
Exosphere - the outermost layer of the Earth's atmosphere, where atmospheric pressure and temperature are low.
Ionosphere - the atmospheric layer between the mesosphere and the exosphere; it is part of the thermosphere.
Mesosphere - the atmospheric layer between the stratosphere and the ionosphere.
Stratosphere - the atmospheric layer between the troposphere and the mesosphere. The stratosphere is characterized by a slight temperature increase with altitude and by the absence of clouds.
Thermosphere - the layer of the atmosphere located above part of the ionosphere (starting at the coldest part of the atmosphere) and below outer space; it consists of the exosphere and part of the ionosphere.
Troposphere - the lowest layer of the Earth's atmosphere. The weather and clouds occur in the troposphere .

8-10. Read the definitions in the word bank below, then label the hurricane diagram.
Word Bank:
Eye - The calm, center of the hurricane.
Eyewall - The wall of dense thunderclouds surrounding the eye. The strongest winds of the hurricane are in the eyewall.
Spiral Rainbands - A series of long, spiraling bands of rain clouds in a hurricane.

A tornado is a violent, column-like system of rapidlyrotating air that is in contact with the ground. Most tornadoes are funnelshaped. Although tornadoes are shortlived (they usually last for a few
In the Northen
Hemisphere (north of the equator), most tornadoes rotate in a counterclockwise direction.
In the Southern
Hemisphere (south of the equator), most tornadoes rotate in a clockwise direction. minutes), they can be very destructive and even deadly.
Tornadoes form in thunderstorms, when unstable hot air near the ground rises and meets cooler air above in thunder clouds.
Tornadoes can form at any time of the year, but most form from
March to August (in the Northern Hemisphere).
The average wind speeds in most tornadoes are about 112 mph
(180 km/h) or less. Winds in the most extreme tornadoes can be over 300 mph (500 km/h).
Tornadoes are ranked using a scale called the Fujita Scale, five categories of wind speed that are estimated the damage left behond
(these are not wind speed measurements, since most wind-speed measuring devices are destroyed during tornadoes, and since the tornadoes die out so quickly, Doppler radar wind measurements are not usually done).
F-5 tornadoes are the most dangerous type (and the rarest type).

Hurricane Tracking
Track the course of a hurricane over time.
Track a hurricane (the symbol for a hurricane is and the symbol for a tropical storm is ) whose coordinates are:


10ºN, 40ºW -- tropical storm
12ºN, 45ºW -- tropical storm
 15ºN, 50ºW -- tropical storm
