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.
occurs when colder air moves towards warm air; represented as a blue line with triangles
warm air moving towards cold air, and it goes above the cold air
occurs when the air masses are not moving. they can produce light, wind, and precipitation
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
form in low altitudes; masses of puffy white clouds with flat bases; fair weather or thunderstorms
form in low altitudes; layers of smooth, even sheets; fog, fair weather, rain, or snow
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
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.
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.
