Chapter 17 - The Atmosphere
Form of oxygen that combines three oxygen atoms into each molecule. Forms a protective layer that is crucial to life on Earth, protecting us from harmful UV radiation.
The bottom layer of the atmosphere, where temperature decreases with an increase in altitude.
The second to the bottom layer of the atmosphere, where temperature remains constant to a height of about 20 km. This is where you can find the ozone layer.
The third layer of the atmosphere, where temperature decreases with height.
The last layer of the atmosphere where there is only a tiny fraction of atmosphere and temperature increases with altitude.
|Summer Solstice|| |
First official day of summer. The sun is vertical at Latitude 23.5° N, so the Northern Hemisphere leans towards the sun.
|Winter Solstice|| |
First official day of winter. The sun is vertical at Latitude 23.5° S, so the Northern Hemisphere leans away from the sun.
|Autumnal Equinox|| |
First day of Autumn. The sun is vertical at the equator.
|Spring Equinox|| |
First day of Spring. The sun is vertical at the equator.
A measure of the average kinetic energy of the individual atoms or molecules in a substance.
The transfer of heat through matter by molecular activity. The energy molecule is transferred by collision between molecules.
The transfer of heat by mass movement or circulation within a substance.;
The transfer of energy through space by electromagnetic waves.
Occurs when light bounces off an object.
Produces a larger number of weaker rays from the sun that travel in different directions.
|Greenhouse Effect|| |
The heating of Earth's surface and atmosphere from solar radiation being absorbed and emitted by the atmosphere, mainly caused by water vapor and carbon dioxide.
The fraction of total radiation that is reflected by any surface.
A line that connect points that have the same temperature.
