Nuclear fusion occurs in the Sun''s core, where the temperature and pressure are extremely high. The immense gravitational force from the Sun''s mass creates pressure that

How do winds form? – Eschooltoday

How does the sun create winds? In the diagram above, notice how cool air falls, resulting in high pressure, and moving towards regions of low pressure. Anywhere and each time there are differences in atmospheric (air) pressure, there will be wind because air will move from the high-pressure area to the low-pressure area.

How does the sun heat the earth?

How does the sun heat the earth? Question Date: 2005-01-23 Answer 1: The sun heats the earth through radiation. Since there is no medium (like the gas in our atmosphere) in space, radiation is the primary way that heat travels in space. When the heat reaches
