They form in atmosphere when reactions take place among primary pollutants and other substances
What are photochemical reactions ?
Reactions triggered by strong sunlight
What is atmosphere pressure ?
Atmosphere pressure is simply the weight of air above
How many layers is the atmosphere divided into ?
In what layer do most weather phenomena occur ?
Where does most energy that drives weather and climate come from ?
What crates winds and dives the ocean’s currents ?
It is the unequal heating of Earth that creates winds and drives the ocean currents. These movements transport heat from the tropics toward the poles in an attempt to balance energy differences. The results of these processes are the phenomena we call weather .
What is rotation ?
Rotation is the spinning of Earth about its axis.
The axis is an imaginary line running through the north and south poles. Our planet rotates once every 24 hours, producing the daily cycle of daylight and darkness
What is revolution ?
Revolution is the movement of Earth in its orbit around the sun. Earth travels at nearly 113,000 kilometers per hour in an elliptical orbit about the sun
What are the degrees the Earth is tilted ?
What is length of daylight determined by ?
It is determined by Earth’s position in orbit.
What are the three mechanisms for energy transfer ?
Conduction, convection & radiation
What can radiate energy travel through ?
Radiant energy can travel through the vacuum of space
Do hot or cold objects radiate more energy ?
Hotter objects radiate more total energy per unit area than colder objects do
What is reflection ?
Reflection occurs when light bounces off an object. About 30% of the solar energy reaching the outer atmosphere is reflected back to space
Does land or water heat to higher temperature faster ?
Land heats more rapidly and to higher temperatures than water. Land also cools more rapidly and to lower temperatures than water. Temperature variations, therefore, are considerably greater over land than over water.
What is a coast called in which winds blow from the ocean onto the shore ?
What is albedo ?
Albedo is the fraction of the total radiation that is reflected by any surface. Many clouds have a high albedo and therefore reflect a significant portion of the sunlight that strikes them back to space
What does the extent of cloud cover influence ?
By reducing the amount of incoming solar radiation the maximum temperatures on a cloud -covered day will be lower than on day when the clouds are absent and the sky is clear.At night, clouds have the opposite effect.
Clouds act as a blanket by absorbing outgoing radiation emitted by Earth and reradiating a portion of it back to the surface. Thus cloudy nighttime air temperatures do not drop low as they would on a clear night. The effect of cloud cover is to reduce the daily temperature range by lowering the daytime maximum and raising the nighttime minimum .
What type of lines connects points of the same temperature ?
