weather and climate Flashcards
Precipitation-
the amount of water that returns to Earth’s surface from the atmosphere
Humidity-
the amount of water vapor in the atmosphere
Air Temperature-
the amount of energy within moving particles which we interpret as how hot or cold something is
Air Pressure-
the weight of the atmosphere pressing down on Earth
Wind-
natural movement of air
Cloud cover-
the type of clouds in the atmosphere and how much of the sky they cover
Rain is
water in the form of a liquid that falls through a warm or cool atmosphere.
Sleet -
snow melts when falling to Earth, then refreezes before hitting the ground.
Hail is
solid ice that mostly falls during thunderstorms.
Snow is a
solid that forms when water vapor freezes in the atmosphere.
Weather
Weather can differ day-to-day and even hour-to-hour. It can be rainy one hour, then bright and sunny the next. In the desert it can rain that is the weather but it usually doesn’t rain so the climate is dry.
Climate
Climate looks at long-term weather patterns.
climate zone
Earth is split into climate zones according to similar average temperatures and precipitation rates.
meteorologist
people who study weather, share predictions of future weather to help people make plans.
hygrometer
Tool used to measure humidity
thermometer
Tool used to measure air temperature
tropical climate zone
Tropical climates are warm, receive large amounts of precipitation and found near the equator.
temperate climate zone
Temperate climates are found in between tropical and polar climates.
polar climate zone
Polar climates are the farthest from the equator and have year-round cold temperatures with little precipitation.
renewable resources
Renewable resources are enrgy resource that will never run out
Which factors affect climate? Why/how?
Distance from Equator:Areas near the equator receive more direct sunlight, allowing more time for their atmospheres to warm up. Areas far from the equator do not receive as much direct sunlight.
Elevation:The higher up a location is, the colder it is. This is because there is less air pressure.
Large bodies of water:Large bodies of water, such as the ocean, take longer to cool or heat up.
Lines of longitude
run from the North Pole to the South Pole. The Prime Meridian is 0 degrees longitude. Places are measured as east or west of the Prime Meridian.
Lines of latitude
are parallel to the equator. The equator is an imaginary line that is halfway between the North and South Poles. The equator is 0 degrees latitude and places are measured as North or south of the equator.
Equator
A imaginary line with 0 degrees latitude that runs throught the middle of Earth. It is the most hottest with most intense sunlight there.
Seasons are caused by the
tilt and daily spin of the Earth and yearly orbits. When an area is tilted towars the sun it is summer there.
If it is winter in the northern hemisphere
Then it’s summer in the southern hemisphere.
Atmospheric circulation is cause by
warm air rising then getting cooled and sinking causing air.
Wind ocuurs in the atmosphere but is cause by
uneven heating in Earth’s geosphere and hydrosphere.
Earth’s geosphere and hysrosphere makes wind by
air above land heats up faster than air above water. Warm air above land expands and rises, and heavier, cooler air rushes in to take its place, creating wind.
