The sun powers the wind by heating up parts of the earth more than others. Wind is the movement of air. The sun heats the air, and the warm air rises. This rising warm air makes the cooler air from the surrounding areas come in to replace it.
Where does the initial source of energy come from that creates winds?
Wind is caused by the uneven heating of the atmosphere by the sun, variations in the earth’s surface, and rotation of the earth. Mountains, bodies of water, and vegetation all influence wind flow patterns,. Wind turbines convert the energy in wind to electricity by rotating propeller-like blades around a rotor.
What source of energy creates winds and surface currents?
Surface currents in the ocean are driven by global wind systems that are fueled by energy from the sun. Patterns of surface currents are determined by wind direction, Coriolis forces from the Earth’s rotation, and the position of landforms that interact with the currents.
What is the primary energy source for surface currents?
Large-scale surface ocean currents are driven by global wind systems that are fueled by energy from the sun. These currents transfer heat from the tropics to the polar regions, influencing local and global climate.
Where do surface currents develop from?
Surface currents are created by three things: global wind patterns, the rotation of the Earth, and the shape of the ocean basins. Surface currents are extremely important because they distribute heat around the planet and are a major factor influencing climate around the globe.
What is the primary cause of winds?
The primary source of wind is caused by the unequal heating of the earth’s surface by the sun. When one area is heated quicker than other areas, the air warms, expands, becomes lighter, and rises. This causes the cooler heavier air to rush in and take its place. This rush of cooler air is what we know as the wind.
What are the 3 types of ocean currents?
Oceanic currents are driven by three main factors:
- The rise and fall of the tides. Tides create a current in the oceans, which are strongest near the shore, and in bays and estuaries along the coast. …
- Wind. Winds drive currents that are at or near the ocean’s surface. …
- Thermohaline circulation.
What is the relationship between the movement of the atmosphere and surface currents?
The movement of the atmosphere or atmospheric circulation refers to the movement of air. Surface currents are ocean currents that don’t depend on weather but are influenced by global wind patterns, the rotation of the Earth, and the shape of the ocean basins.
What are the two main types of currents?
The two basic types of currents – surface and deep-water currents – help define the character and flow of ocean waters across the planet.
What are the 5 major ocean currents?
There are five major gyres: the North Atlantic, the South Atlantic, the North Pacific, the South Pacific and the Indian Ocean Gyre, see figure 1. The Antarctic Circumpolar Current is situated in the Southern Ocean and constantly circles around Antarctica because there are no land masses to interrupt the currents.
What is the source of energy for the global conveyor belt?
There is constant motion in the ocean in the form of a global ocean conveyor belt. This motion is caused by a combination of thermohaline currents (thermo = temperature; haline = salinity) in the deep ocean and wind-driven currents on the surface.
What is responsible for deepwater currents?
Deep ocean currents (also known as Thermohaline Circulation) are caused by: … The sinking and transport of large masses of cool water gives rise to the thermohaline circulation, which is driven by density gradients due to variations in temperature and salinity. The earth’s rotation also influences deep ocean currents.
