SOLAR SYSTEM

Detailed explanation-1: -Earth’s surface warms up in the sunlight. At night, Earth’s surface cools, releasing heat back into the air. But some of the heat is trapped by the greenhouse gases in the atmosphere. That’s what keeps our Earth a warm and cozy 58 degrees Fahrenheit (14 degrees Celsius), on average.

Detailed explanation-2: -The weather is mainly affected by the sun that produces heat and raise the temperature of earth’s surface, oceans and atmosphere. the sun’s heat will change the atmosphere more frequently. The time of sunrise and sunset also changes throughout the year.

Detailed explanation-3: -The Sun plays a key role in the hydrological cycle, constantly evaporating water into the atmosphere. Some of that water is returned as rain, snow and dew. Part of this precipitation is rapidly evaporated back into the atmosphere. Some drains into lakes and rivers to commence a journey back to the sea.

Detailed explanation-4: -Solar heating of the Earth’s surface is uneven because land heats faster than water, and this causes air to warm, expand and rise over land while it cools and sinks over the cooler water surfaces.

Detailed explanation-5: -The core of the sun is so hot and there is so much pressure, nuclear fusion takes place: hydrogen is changed to helium. Nuclear fusion creates heat and photons (light). The sun’s surface is about 6, 000 Kelvin, which is 10, 340 degrees Fahrenheit (5, 726 degrees Celsius).

Detailed explanation-6: -Since there is no medium between the surface of Earth and Sun, heat transfer through conduction is not possible. Radiation is the method of heat transmission that occurs without the help of a medium. So, we can say that the heat from the Sun reaches the Earth through radiation.
