The primary cause of weather change is the Sun as the heat transferred from the Sun is absorbed by the Earth and spreads in its atmosphere. Due to Earth's rotation and tilted axis, the Sun's rays strike the Earth at different angles throughout the day. The Sun's radiation strikes the Earth's surface, thus warming it. As the surface's temperature rises due to conduction, heat energy is released into the atmosphere, forming a bubble of air that is warmer than the surrounding air. This bubble of air rises into the atmosphere. Solar power drives Earth's climate. Energy from the sun heats Earth's surface, warms the atmosphere, provides energy for photosynthesis, causes evaporation, drives the weather and water cycles, and powers the ocean currents. All of the energy from the Sun that reaches the Earth arrives as solar radiation, part of a large collection of energy called the electromagnetic radiation spectrum. Solar radiation includes visible light, ultraviolet light, infrared, radio waves, X-rays, and gamma rays. Radiation is one way to transfer heat. Some weather effects that are caused by the Earth absorbing energy from the sun include the formation of winds, changes in atmospheric pressure, and the creation of temperature gradients. The primary cause of weather change is the Sun as the heat transferred from the Sun is absorbed by the Earth and spreads in its atmosphere. Due to Earth's rotation and tilted axis, the Sun's rays strike the Earth at different angles throughout the day. The local weather that impacts our daily lives results from large global patterns in the atmosphere caused by the interactions of solar radiation, Earth's large ocean, diverse landscapes, and motion in space. The Sun is the source of all heat and light on the earth. Energy absorbed and reflected by the earth surface, oceans and the atmosphere play important roles in determining the weather at any place. This is how, the Sun is responsible for causing changes in the weather. Energy is transferred between the Earth's surface and the atmosphere in a variety of ways, including radiation, conduction, and convection. Conduction is one of the three main ways that heat energy moves from place to place. The other two ways heat moves around are radiation and convection. The Earth's climate system depends entirely on the Sun for its energy. Solar radiation warms the atmosphere and is fundamental to atmospheric composition, while the distribution of solar heating across the planet produces global wind patterns and contributes to the formation of clouds, storms, and rainfall.
