Climate Zones & Ocean Currents
WHAT ARE CLIMATE ZONES & OCEAN CURRENTS?

Ocean currents are directed, continuous movements of ocean water. They are found on the ocean’s surface and in its depths, and can be local or global. Ocean currents are driven by winds, water density, and tides. Sea floor features and coast lines can influence the speed and direction of currents.

Coriolis Effect

Coriolis Effect

The Coriolis effect is a global wind pattern that is caused by the rotation of Earth, which rotates on its axis every 24 hours. Because of the rotation and tilt of Earth’s axis, certain latitudes move faster than others. For example, the North and South poles have less distance to move to make a complete rotation and are moving at a slower rate. The Equator has the furthest distance to move and is moving at the fastest rate. As air currents move from one latitude to another, they begin moving at the same rate of speed as their point of origin. However, the latitude that they are moving towards may be moving faster or slower. Consequently, the air currents “bend” because the Earth under them is moving at different rates. Air currents are deflected to the right in the Northern Hemisphere and to the left in the Southern Hemisphere.

Light Intensity

Light Intensity

Light intensity measures how much energy is hitting a surface. Light travels in a straight line until it hits something else that may block or reflect the light in a different direction. When light travels in a straight line from the Sun to Earth and hits its surface at a 90° angle, it is the most intense and transfers the most energy (solar radiation). When light hits the surface of Earth at a smaller angle, less energy and solar radiation is transferred because the light is spread out over a larger area of Earth’s surface.
