hi mate,
Answer : Energy is transferred from the sun to Earth via electromagnetic waves, or radiation. Most of the energy that passes through the upper atmosphere and reaches Earth's surface is in two forms, visible and infrared light.
The weather and climate on Earth are dictated by the amount of incoming energy from the Sun. Earth's energy budget explains that if the incoming and outgoing radiation are equal, then the climate is in equilibrium.
This balance is achieved or not achieved depending on how this incoming energy interacts with the Earth and objects on it through phenomena such as scattering, reflection, absorption, and energy transformations. Energy can be converted, transported and stored in a variety of forms. Overall, how energy acts once it has reached the Earth plays a significant role in Earth's climate. Energy flows are the energy transformations and movement that occur once energy has reached the Earth. These flows describe how energy is distributed and how it interacts with objects, determining certain climate properties.
Balance : The Earth then radiates power from all of the flows back into space in the form of thermal radiation. The Earth stays nearly totally balanced in terms of its temperature due to how the flows interact with each other and how solar energy reaches the Earth.
This is due to Earth's energy budget. Increases in greenhouse gases like carbon dioxide and methane are leading to slightly less heat being radiated into space than the amount of energy coming in. This difference amounts to roughly 1W/m², a very small difference. Over several decades this 1W/m² has led to a warming climate especially warmer oceans, even though it is a seemingly insignificant power, equating to the output of roughly 1 Christmas tree light for every square meter of Earth's surface.
i hope it helps you.
The process of photosynthesis in plants involves a series of steps and reactions that use solar energy, water, and carbon dioxide to produce organic compounds and oxygen. There are two main sets of reactions: energy-transduction reactions (commonly called light reactions) and carbon-fixation reactions (commonly called dark reactions).
In the energy-transduction reactions, solar energy is converted into chemical energy in the form of two energy-transporting molecules, ATP and NADPH. When solar energy reaches plant cells and excites special chlorophyll molecules, they release a high-energy electron (check out the related strategy here). The release of this electron sets off a chain of electron-trading and energy-transferring events between several intermediary molecules, and the last molecule to form and hold the electrons in this chain is NADPH.
The excited chlorophyll molecule’s electrons need to be replaced, and these electrons come from water. With the help of enzymes and solar energy, water is split (photolysis) into electrons, protons (H+), and oxygen. The electrons go to the chlorophyll, while the protons contribute to a proton gradient that is used to power the synthesis of a second energy-carrying molecule, ATP. The oxygen is a byproduct of the whole process.
The chemical energy in NADPH and ATP is then used to power steps in the subsequent carbon-fixation reactions.
