Welcome To Class Why is a person working out and sweats a lot more likely to get heat stroke when the humidity is high?

Agenda Clouds notes Demo Cloud Classification –Foldable Activity Observe Clouds Concept Map

Clouds What is a cloud? –Small water droplets or ice crystals suspended in the air –Air is cooled and water vapor condenses

Clouds How do clouds form? Water vapor condenses on condensation nuclei –Solid particle in the atmosphere that provides a surface for water to condense –Ice, salt, dust, other particle

Cloud Formation Adiabatic Cooling –air mass temp. decreases as the air mass rises and expands Mixing – two masses of moist air meet and cool

Cloud Formation Lifting – forced upward movement of air that expands and cools Advective Cooling – air mass temp. decreases as the air mass moves over a cold surface

Types of Clouds Low Level – Stratus, nimbostratus, stratocumulus, some Cumulus Mid-level – Cumulus, altocumulus, altostratus High Level – Cirrus, Cirrostratus, Cirrocumulus

Key Cloud Terms Nimbo, Nimbus – rain Alto – middle Stratus – layered Cumulus – cotton ball, fluffy look, heap Cirrus – feathery, curl of hair

Other Clouds Contrails – formed from exhaust from a jet Mammatus - pouch-like cloud structures and a rare example of clouds in sinking air –Seen after a storm Pileus Clouds – clouds found attached to a mountain top

Foldable Activity Fold Paper in half Cut two lines (create 3 tabs) Label the tabs as Cumulus, Stratus, and Cirrus On the inside write information about each type of cloud
