Feb 2, 2024 · The sun is an ordinary star, one of about 100 billion in our galaxy, the Milky Way. The sun has extremely important influences on our planet: It drives weather, ocean currents, seasons, and climate, and makes plant life possible through photosynthesis. Without the sun’s heat and light, life on Earth would not exist.

The most obvious and direct aspect of the Sun's importance is its role as our main source of light and heat. Sunlight is essential for the functioning of terrestrial ecosystems, as it allows plants to carry out photosynthesis, the process by which they convert solar energy into food and release oxygen into the environment. Without photosynthesis, t...
The Sun is the main driver behind our planet's weather patterns. The amount of solar radiation reaching the Earth varies throughout the year due to the tilt of the Earth's axis of rotation and its elliptical orbit around the Sun. These seasonal changes in solar radiation are responsible for the seasons of the year and They have a direct impact on w...
The water cycle on Earth is also intrinsically linked to the Sun. The Sun heats the Earth's surface, causing water to evaporate from oceans, rivers and lakes. This vaporized water rises into the atmosphere, where it condenses to form clouds. The clouds then move, driven by the winds, and when the water droplets gather together enough, they fall as ...
In addition to solar energy, the Sun plays a crucial role in many renewable and non-renewable energysources. Let's see the reason one by one:
The Sun could not harbor life as we know it because of its extreme temperatures and radiation. Yet life on Earth is only possible because of the Sun’s light and energy.
Oct 19, 2023 · The sun is the closest star to Earth. Even at a distance of 150 million kilometers (93 million miles), its gravitational pull holds the planet in orbit. It radiates light and heat, or solar energy, which makes it possible for life to exist on Earth. Plants need sunlight to grow.
May 6, 2024 · We can’t live without the Sun! Life on Earth depends on the Sun. Here are just a few reasons why: The Sun’s gravity holds our entire solar system together. Our solar system is even named after the Sun (the Latin word for Sun is “sol”). Heat from the Sun makes Earth warm enough to live on.

13. Upcoming Missions. Overview. The Sun's gravity holds the solar system together, keeping everything – from the biggest planets to the smallest particles of debris – in its orbit. The connection and interactions between the Sun and Earth drive the seasons, ocean currents, weather, climate, radiation belts and auroras.
