Meteorology |
study of the earth's atmosphere |
|
Weather |
can be traced back to the sun warming the earth unevenly |
|
Air warms
|
it rises and cooler air replaces it |
|
When warm air rises |
leaves behind an area of low pressure any moisture that has evaporated is carried upward and condenses as it cools, forming clouds. |
|
Precipitation |
this will occur if the clouds are substantial enough |
|
Regions of low pressure |
are associated with wet and windy weather conditions |
|
Regions of high pressure |
associated with clear and calm weather |
|
Winds |
created by pressure differences between regions where the air is falling (high pressure) and where the air is rising (low pressure) The greater the pressure difference, the stronger the winds. |
|
Climate |
term used to explain long-term patters of temperature, humidity and amount of sunshine. |
|
Seasons |
Earth orbits sun e, this means that different hemispheres are exposed to different amounts of sunlight throughout the year.
Since the sun is our source of light, energy, and heat, the changing intensity and concentration of its rays gives rise to the seasons. |
|
Tides |
caused by the pull of the moon and the sun on the Earth's oceans. Movement patters are directly tied to the phases of the moon. |
|
Moon phases |
when moon appears a quarter fool it is a crescent moon. When it appears larger than a quarter full it is a gibbous moon. |
|
Waxing |
when moon appears to increase in size it is going from the new phase to the full phase |
|
Waning |
when it appears to be getting smaller it is waning |
|
Tides |
when subject to tidal forces, planets deform as if they are being pushed from the top and bottom. Two bulges appear on either side of the planet. |
|
High Tide |
The moon pulls water toward it, which causes the bulge toward the moon. on the other side of the earth the moon pulls the earth away from the water. if you are on a coast and the moon is directly overhead you are witnessing high tide. |
|
Seas |
sea is a large body of water that is surrounded by land or attached to another body of water. |
|
Rivers |
Rivers often flow into other bodies of water. For instance, the Mississippi River flows into the Gulf of Mexico. |
|
ocean |
An ocean, which is the largest body of water on Earth, is generally thought of as having no boundaries |
|
Lakes |
a body of water surrounded by land |
|
Estuary |
a body of water formed where freshwater from rivers and streams flows into the ocean, mixing with the seawater |
