Best answer: What is the main source of energy that drives the global climate?

The climate system is powered by radiation from the sun, of which approximately 49% is absorbed by the Earth’s surface, and 20% is absorbed by the atmosphere (Kiehl & Trenberth 1997). This energy warms the planet, but the warming also causes Earth to start radiating energy back into space.

What is the primary source of energy for the climate system?

1) The Sun is the primary source of energy for Earth’s climate system. Sunlight across the globe: A satellite image shows sunlight gleaming across the surface of the Earth.

What drives the global climate system?

The climate system is driven by energy that is received from the sun. Some of this energy is reflected back into space, while the rest is absorbed by the land and ocean and re-emitted as radiant heat; this is known as the heat balance of the Earth.

What is the main energy source that drives global climate a solar wind mechanical D heat?

Earth’s rotation influences global flow of air and water. 2.3 Earth’s weather and climate are mostly driven by energy from the Sun. For example, unequal warming of Earth’s surface and atmosphere by the Sun drives convection within the atmosphere, producing winds, and influencing ocean currents.

What is our main source of energy?

Our energy supply comes mainly from fossil fuels, with nuclear power and renewable sources rounding out the mix. These sources originate mostly in our local star, the Sun.

What are the main components of the climate system?

Its components The climate system, as defined in this Report, is an interactive system consisting of five major components: the atmosphere, the hydrosphere, the cryosphere, the land surface and the biosphere, forced or influenced by various external forcing mechanisms, the most important of which is the Sun (see Figure …

What are the three main processes that control Earth’s climate?

> The Earth’s climate is influenced by many factors, including solar radiation, wind, and ocean currents. Researchers try to integrate all of these influencing variables into their models. Many of the processes involved are now well understood.

What are the 2 main components of climate?

Two of the most important and unique are water and carbon. They are important for climate, and they are important for life: Almost all living things contain and use carbon in different forms for our bodies and as part of the cycle of energy (either photosynthesis in plants or respiration in animals).

What are sources of solar energy?

Solar energy is any type of energy generated by the sun. Solar energy is created by nuclear fusion that takes place in the sun. Fusion occurs when protons of hydrogen atoms violently collide in the sun’s core and fuse to create a helium atom.

How does the sun’s energy affect the movement of global winds?

When the Earth’s surface absorbs the sun’s energy, it turns the light into heat. This heat on the Earth’s surface warms the air above it. The air over the Equator gets warmer than the surface air near the poles. … This moving air is what we call wind.

Which of the following explains why some energy sources are renewable?

Renewable energy sources can be replaced naturally at current consumption rates, whereas nonrenewable energy sources cannot be replaced easily. … Renewable energy sources are replenishable and are virtually inexhaustible by human consumption, whereas nonrenewable sources do not form in a short period of time.
