What are the three ingredients of weather?

air, water, and heat/temp


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.


How much stuff there is


How much space something takes up


the amount of mass in a given volume


the force pushing on an area or surface

What is the relationship between altitude and air pressure?

As the altitude increases, pressure decreases

Relationship between water pressure and weather


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.

What happened in the soda can demo?

The can was crushed because when it was put in cold water, the warm air exits quickly. When the warm air exits, the pressure inside decreases, but the pressure on the outside stays the same, causing the can to crush

The Coriolis Effect on wind

winds in the northern hemisphere blow to the right; winds in the southern hemisphere blow to the left


cold, warm, stationary, and occluded. When cold fronts move toward warm fronts the cold air forces itself under the warm air. The warm air is lifted and it cools and forms water vapor and clouds.

Cold Fronts

occurs when colder air moves towards warm air; represented as a blue line with triangles

Warm Fronts

warm air moving towards cold air, and it goes above the cold air

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


precipitation that falls in temperatures above freezing


precipitation that falls in temperatures cold enough to go from water vapor to solids


when raindrops pass through freezing air near the Earth's surface

Cumulus Clouds

form in low altitudes; masses of puffy white clouds with flat bases; fair weather or thunderstorms

Stratus Clouds

form in low altitudes; layers of smooth, even sheets; fog, fair weather, rain, or snow

Cirrus Clouds

form in high altitudes; curly, white, thin, and feathery; fair weather or approaching storms

What causes thunder and lightning?

The movement of electrons.

How are hurricanes and tornadoes different?

Tornadoes form on land and in water, but hurricanes form only in water.

How are hurricanes and tornadoes similar?

Hurricanes and tornadoes both produce powerful, destructive winds and can both form on water

The properties of air

air has mass, and because it has mass it has density

Front Movement

cold fronts move under warm air, warm fronts move under cold air, stationary fronts don't move, occluded fronts are cool air moving towards each other and traps the warm air above.

Relationship between wind and air pressure

Wind moves from high pressure to low pressure


Middle height clouds





Water cycle

Sun, evaporation, condensation(clouds), precipitation, runoff, accumulation

What happened in the egg demo?

When the paper was lit, the air inside the bottle got hotter and expanded. Some of the air escaped from the bottle. When the flame went out, the air inside the bottle cooled down and so the air pressure decreased. This meant the pressure outside the bottle was greater than inside the bottle. This pushed the egg into the bottle.

What causes different climates on Earth?

The Earth is tilted on its axis so as it turns, different parts of the Earth gets direct sunlight. The Equator always gets direct sunlight.The poles do not get direct sunlight.
