Earth and Space: Questions and Answers
Amplitude - ansThe height that a wave rises above or falls below a its resting position.
Determines the strength of a wave.
Big Bang Theory - ansThe most accepted scientific theory of how the universe was created.
The universe began at a single point and the point exploded to create our current universe.
Climate - ansThe average weather experienced over a long period of time.
Cold Front - ansA front that is created when a cold air mass moves into a warm air mass.
Condensation - ansThe movement of water from gas to liquid (water vapor to water).
Hint: Clouds
Continental Drift - ansTheory that states that Earth's continents have moved over time.
Continental Plate - ansPlates underneath land.
Thicker but less dense.
Convection Current - ansThe circulation of magma in Earth's mantle.
Causes plates to move around.
Convergent Boundary - ansBoundary where tectonic plates are colliding.
Forms mountains, volcanoes and earthquakes.
Crest - ansThe highest point of a wave.
, Divergent Boundary - ansBoundary where tectonic plates are moving apart.
Forms rift valleys and mid-ocean ridges.
Eclipse - ansOccurs when there is a perfect alignment between the Earth, Moon and Sun.
Evaporation - ansThe movement of water from liquid to gas (water to water vapor).
Frequency - ansThe number of wavelenghts that pass a certain point per second.
Full Moon - ansMoon phase where Moon is 100% visible.
Occurs when the Earth is in between the Moon and Sun.
Galaxy - ansA collection of stars held together by gravity.
There are 3 types: spiral, elliptical and irregular.
Global Wind - ansCaused by air circulation and Earth's rotation.
Air rises and sinks because of heat (solar energy) absorbed by air.
Gravity - ansThe force that keeps all the planets in orbit around the Sun in our solar system.
It also keeps all the stars in our galaxy together.
It also keeps the Moon in its orbit around the Earth.
Groundwater - ansWater that is stored underground.
Examples: aquifer, well, etc.
H-R Diagram - ansA chart that shows the relationship between a star's brightness and temperature.
