Mrs. Adkins Unit 3

What are the three ingredients of weather? air, water, and heat/temp
Weather the current state of the atmosphere
What is the location of weather? the troposphere
Similarities between weather and climate They both involve weather and atmosphere
Difference between weather and climate Weather is the weather on a day-to-day basis. Meanwhile, climate is the weather over a long period of time.
Mass How much stuff there is
Volume How much space something takes up
Density the amount of mass in a given volume
Pressure the force pushing on an area or surface
What is the relationship between altitude and air pressure? As the altitude increases, pressure decreases
Cause of wind the uneven heating of Earth and its atmosphere. The uneven heating creates convection currents.
How are temperature and pressure related to each other and wind? colder temp=more dense and pressure. warmer temp=less dense and pressure. This relates to convection currents.When it is warm the molecules separate which causes low pressure, when it is cold, they condense and create higher pressure.
The Coriolis Effect on wind winds curve due to the rotation (spinning) of Earth)
Fronts cold, warm, stationary, and occluded. When different air masses collide
Cold Fronts occurs when colder air moves towards warm air; can create storms; represented as a blue line with triangles
Warm Fronts warm air moving towards cold air, and it goes above the cold air; can create light rain/clouds; represented as a red line with half circles
Stationary Fronts occurs when the air masses are not moving. they can produce light wind and precipitation
Occluded Fronts involves three different air masses: one cold, one cool, and one warm
Types of precipitation Rain, snow, sleet, and hail
Rain precipitation that falls in temperatures above freezing (>32 degrees F or 0 degrees C)
Snow precipitation that falls in temperatures cold enough (<32 degrees F or 0 degrees C) to go from water vapor to solids
Sleet when raindrops pass through freezing air near the Earth's surface
Cumulonimbus Clouds as warm air is forced upward rapidly, these clouds are created. These are the places where thunderstorms and tornadoes form.
What forms when warm, ocean air evaporates and produces a spinning cloud with an eye? What forms when warm, ocean air evaporates and produces a spinning cloud with an eye?
How are hurricanes and tornadoes similar? How are hurricanes and tornadoes similar?
The properties of air air has mass, and because it has mass it has density
Relationship between wind and air pressure Wind moves from high pressure to low pressure
Water cycle Sun, evaporation, condensation(clouds), precipitation, runoff, accumulation
What would a continental, polar air mass contain? dry, cold air
What would a maritime tropical air mass contain? humid, warm air
Why do we have a sea breeze? During the day, the sun heats the earth unevenly....the sand is warmer than the water. Air moves from the water (high pressure) to the sand (lower pressure)
Why do we have global winds? The sun always heats the equator more directly than the poles. Equator is hot and poles are cold. This difference in air temperatures creates differences in air pressures, creating winds.
