__**Low Latitudes**__- Between 30 degrees south and 30 degrees north latitude is a zone known as the low latitudes. This zone includes the Tropic of Capicorn, and the Tropic of Cancer. Portions of the low latitudes receive the direct rays of the sun year-round. Places located in the low latitudes have warm to hot climates.

**__High Latitudes__**- The Earth's polar areas, which stretch from 60 degrees north to 90 degrees north and from 60 degrees south to 90 degrees south, are called the high latitudes. When either the Nothern or the Southern Hemisphere is titled toward the sun, its polar area recieves nearly continious, but indirect, sunlight. From about March 21 to about September 23, the polar area from north of the Arctic Circle experiences continious daylight or twilight. The polar area south of the Antarctic Circle experiences continious daylight or twilight for the other six months of the year.


 * __ Midlatitudes- __** The most variable weather on Earth is found in the midlands, between 30 degrees north and 60 degrees north in the Nothern Hemisphere and between 30 degrees south and 60 degrees south in the Southern Hemisphere. The midlatitudes generally have a temperature climate-one that ranges from fairly hot to fairly cold-with dramatic seasonal weather changes.

Elevation – Elevation is the relationship between the elevated height of a place and its temperature. Example, thinner air is less dense and gets less heat. Thicker air is denser and retains most heat.

Ocean Currents – Ocean currents move through the oceans, they are caused by many factors that cause winds, storms, rotation, and changes in air pressure. Many affects are also observed with ocean currents.

El Nino – Climate is also affected by a reoccurring thing called El Nino each year, It is a change in the pattern of ocean currents, water temperature, and weather in the mid Pacific region.

Earth's Revolution: Earth take a full year to rotate around the sun. While is doing that the earth has different seasons, which are summer, winter, spring, ect. When the north is in summer south is in winter.

The Horse Latitudes: Global winds are diverted north and south, in a narrow way. Two other narrows know to be north Tropic of Cancer and south Tropic of Capricorn. Crews of ships took a sail and got stranded because there was no wind.

Weather and the Water Cycle: Wind and water work together to affect the weather in a important way. Presipitation is made so rain can be evopored and be used in a cycle again
