liquid things
what is water vapor
Water in the form of a gas. when we see clouds, we actually are seeing liquid water in the clouds.
what is atmosphere
The layer of gases that surrounds a planet.
what is the lunar eclipse
An eclipse that occurs when the Moon moves through the shadow of the Earth and is blocked from view.
what is a galaxy
A collection of stars, dust, and gas bound together by gravity
single landmass that broke apart 200 million years ago and gave rise to today's continents
pangaea
what is evaporation
Process in which a substance changes from a liquid to a gas.
what layer is the troposphere
The lowermost layer of the atmosphere; temperature decreases with altitude
what is the solar eclipse
Occurs when moon passes directly between the Earth and Sun; the Moon's shadow blocks the Sun from view.
what is a red giant
A star that expands and cools once it runs out of hydrogen fuel
When two continental plates collide large __________ will usually form
moiuntants
what is condensation
Process in which a substance changes from a gas to a liquid.
what layer is the mesosphere
Layer between the stratosphere and thermosphere; temperature decreases with altitude.
what is solstice
When the position of the Sun is closest to one of the poles
what is a red supergiant
The stage in the life cycle of a massive star during which the star increases in size and becomes very bright.
Process in which sediment is laid down in new locations - building up new land.
deposition
what is transpiration
The release of water vapor into the air through the leaves of plants.
what layer is the stratosphere
Above the troposphere; temperature increases with altitude because of the presence of ozone.
what is equinox
When the position of the Sun is halfway between its position during the solstices
what is a elliptical galaxy
A galaxy shaped like a round or flattened ball, generally containing only old stars
When a collision between two plates pushes the denser plate into and under the other plate __________ takes place
subduction
what is hydrological (water) cycle
The movements of water in and between reservoirs (e.g. oceans, clouds, streams, ice, and ground water).
what layer is the thermosphere
The outer atmosphere where gases are extremely thinly distributed.
what is Coriolis effect
The apparent deflection of a freely moving object like water or air because of Earth's rotation.
what is the H-R diagram
Hertzsprung-Russell diagram, a graph that shows the relationship between a star's surface temperature and absolute magnitude
what happens where 2 continental plates collide and push up creating mountain ranges
continental convergent
