insolation – short for “incoming solar radiation” – it means the amount of the Sun’s energy that reaches Earth at any given place and time.

sea level - The level of the sea's surface, used in determining the height of geographical features such as hills and as a barometric standard.

altitude- The height of an object or point in relation to sea level or ground level.

molecule- A group of atoms bonded together, representing the smallest fundamental unit of a chemical compound that can take part in a chemical reaction.

Lactic Acid Molecule – found in milk!

atmosphere- the air that surrounds the earth.

atmosphere- the air that surrounds the earth.

troposphere- the layer of the earth’s atmosphere closest to the earth’s surface.

air pressure- the force put on a given area by the weight of the air above it.

air pressure- the force put on a given area by the weight of the air above it.

The closer to sea level you are,the higher the air pressure!Air pressure is measured in “millibars” (mb). When you’re close to sea level, there are moremolecules above you, weighing down. This means greater air pressure.

weather – what the troposphere is like at any given time. It includes the following:

air pressureair temperature

windamount of moisture in the air

precipitation

clouds

barometer - an instrument that measures air pressure

thermometer - an instrument that measures temperature
