Why is Earth cooler in winter than in summer?

How can the absorption and reflection of energy in winter be described ?

The earth is cooler because it is farther away from the sun

Explanation:

Summer is hot because the sun is closer. Winter is cold because when it is winter the sun is further away than in the summer. So in the summer the sun is close to the Earth which makes it hot.

the enthalpy of formation of water is given as -285.8kj/mol, which states that the enthalpy of formation is negative.

negative enthalpy of formation indicates that the heat is released during the reaction process. the heat is released from reaction to the surroundings the enthalpy is expressed with a negative sign with the energy given out in the reaction process.

the formation of water takes place by giving out heat which is -285.8 kj/mol.
