What is the Coriolis Effect?

Physical consequence of the Law of Conservation of Angular Movement; as a result of the Earth's rotation, a moving object veers to the right in the Northern Hemisphere, and to the left in the Southern Hemisphere.


What are Polar Easterlies?

Easterly winds located at high latitudes poleward of the subpolar low.


What is Evaporation?

Loss of water vapor from soil, an open body of water, or another exposed surface.


What is Condensation?

Water that collects as droplets on a cold surface when humid air is in contact with it.


What is an Ocean Gyre?

Circular or spiral motion of water, the term usually being applied to a semiclosed current system.


What is the Intertropical Convergence Zone (ITCZ)?

The boundary zone seperating the northwest trade winds of the Northern Hemisphere from the trade winds of the Southern Hemisphere.


What is a Rain Shadow?

A dry region of on the leeward side of a mountain range resulting from a reduction in rainfall.


What is El Niño Southern-Oscillation?

A global event arising from large-scale interactions between ocean and atmosphere.


What is a Microclimate?

Local climate which differs from the general climate of the area;which also, influences the presence and distribution of organisms.


What is the Law of Conservation of Angular Movement?

The principle that the total angular momentum of a system has constant magnitude and direction if the system is subjected to no external force.


What is Photosynthetically Active Radiation (PAR)?

The part of the light spectrum that is used by plants in photosynthesis (wavelengths between 400 and 700 nm).


What is Ozone (03)?

Atmospheric oxygen that is reduced to an ambivalent atmospheric gas by high-energy ultraviolet radiation.


What is a Solstice?

When the Sun is at its greatest distance from the celestial equator.


What is an Equinox?

When the Sun crosses the plane of the celestial equator, making day and night of equal length all over the planet.
