Definitions
meteorology
branch of science concerning the atmosphere and weather
Evaporation
liquid changes into water vapor and warm air goes up
how is fog formed
when moisture in the air is cooled from below and condenses
describe cirrus and cumulus clouds
1) wispy and feathery white
2)fluffy flat bases
how many hydrogen atoms and oxygen atoms are in a water molecule
1) 2 (H2)
2) 1 (O)
= H2O
meteorologist
scientist who studies meteorology
condensation
water vapor encounters cooler temps and creates a cloud
atmosphere
the layers of gasses that surround Earth
describe Stratus and Cumulonimbus clouds
1) flat layered gray clouds generally over the whole sky
2) fluffy white tops with grey bases
what are the approx. elevation of each cloud
1) Cumulonimbus = 15,000 to 60,000 feet
2) Cirrus = 20,000 feet
3) Cumulus = 8,000 feet
4) Stratus = 6,000 feet
air
the invisible gas mixture surrounding Earth
Precipitation
water falls in various forms to Earth
hydrologic cycle
the process by which water moves through the Earth and atmosphere
List the Air Composition percentages
nitrogen 78%
oxygen 21%
other 1%
walk through the process of the water cycle
1) precipitation occurs when it rains
2) rain goes off mountains and hills in run-offs
3) next water goes back up to the sky by transporting off plants or evaporating off the ground
4) Condensation occurs and the water becomes and cloud and rains therefore repeating
air pressure
force put on Earth's surface by the weight of air above it
Run-off
water flows downhill to join streams, rivers, lakes, oceans
List the Earth's sources of water and examples
1) salt water- oceans
2)fresh water- ice caps, glaciers, etc.
how do clouds form
form from condensation of water droplets sticking to sand in the atmosphere
List the 4 purposes of the atmosphere
1) protects the Earth from meteors
2) Provides oxygen to breathe
3) Blocks harmful rays from sun- ozone layer
4) Maintains constant temperature and air pressure
barometer
an instrument used for measuring atmospheric pressure and forecasting the weather
transpiration
water evaporation from plants and trees
what are the three states of matter and what do we call water in each of these three states
1) solid- ice
2) liquid- water
3)gas- vapor
what are the 4 cloud types
1) Cirrus
2) Cumulonimbus
3)Cumulus
4) Stratus
list the order of the atmosphere from highest elevation to lowest using Even The Moon Seems Tiny In Space
1) Exosphere
2) Thermosphere
3) Mesosphere
4) (Ozone) then Stratosphere
5) Troposphere
6) EARTH
