theory
The scientific theory of the evolution of Earth states that changes in our planet are driven by the flow of energy and the cycling of matter through dynamic interactions among the atmosphere, hydrosphere, cryosphere, geosphere, and biosphere, and the resources used to sustain human civilization on Earth.
Jet streams
Jets are fast moving ribbons of air high up in the atmosphere. They are responsible for transporting highs and lows. They affect precipitation and temperatures, and they mark boundaries between massive air masses. The basic idea that drives jet formation is this: a strong horizontal temperature contrast, like the one between the North Poles and the equator, causes a dramatic increase in horizontal wind speed with height. Therefore, a jet stream forms directly over the center of the strongest area of horizontal temperature difference, or the front.
Ocean currents

The world’s ocean is crucial to heating the planet. While land areas and the atmosphere absorb some sunlight, the majority of the sun’s radiation is absorbed by the ocean. Particularly in the tropical waters around the equator, the ocean acts a as massive, heat-retaining solar panel. Earth’s atmosphere also plays a part in this process, helping to retain heat that would otherwise quickly radiate into space after sunset. It also helps distribute heat around the globe. Ocean currents act much like a conveyer belt, transporting warm water and precipitation from the equator toward the poles and cold water from the poles back to the tropics.
vocabulary
temperature – measure hot or cold; measure average kinetic energy.
wind – horizontal movement of air.
land breezes- nightly movements, cold air over land forces up warmer air above sea.
sea breezes – daily movements, cooler, denser air inland forces warm air over land to rise.
global winds – winds, long distances, steady patterns, several weeks.
jet stream – strong winds, west to east at great speeds, at top of troposphere.
humidity – water vapor in air.
climate – pattern weather, particular area, over long time.
ocean currents – water flows through ocean in pattern.
