Question

Draw a diagram to explain the heat budget of the earth.

Answer 1

Explanation:

a drawing of heatbud get of the earth

Answer 2

The balance of incoming and outgoing heat is referred to as the Earth's heat budget. To maintain consistent conditions, the budget must be balanced, just like any other budget, so that entering heat equals outgoing heat.

The balance of incoming and outgoing heat is referred to as the Earth's heat budget. To maintain consistent conditions, the budget must be balanced, just like any other budget, so that entering heat equals outgoing heat.

Conduction, radiation, and latent heat are three mechanisms that return energy absorbed by the Earth to the atmosphere.

Conduction:

The transfer of heat by direct contact between the surface and the environment is known as conduction. Conduction accounts for only a small percentage of the energy transmission between the Earth and the atmosphere due to air's weak thermal conductivity (which suggests it is a good insulator). About 7% of the solar energy that enters the system is transferred by conduction.

Radiation:

• Radiation is produced by all objects with a temperature greater than absolute zero, and the warming Earth is no exception, releasing around 16 percent of the sun's initial energy into space
• While some of the energy produced will move into space, much of it will be absorbed by the atmosphere. The greenhouse effect is based on this
• When solar radiation in short waves  flows through the atmosphere and it is absorbed by the Earth's surface, this is when greenhouse effect occurs.
• The atmosphere, particularly greenhouse gases like CO2, methane, and water vapour, absorbs this infrared radiation instead.

Latent Heat:

• The biggest route for heat exchange between the ground or oceans and the atmosphere is latent heat exchanged through phase changes; heat produced or absorbed when water travels between solid, liquid, and vapour phases.
• To make liquid water evaporate, heat is necessary, and when water vapour is formed, heat is taken from the ocean and released to the atmosphere with the water vapour.
• When water vapour condenses into rain, it returns heat to the oceans. Ice is formed and dissolved in the same way. When ice melts, heat is absorbed, and when ice develops, heat is released, and these phase transitions transmit heat between the oceans and the atmosphere.
• The heat received by the atmosphere is reflected back into space to fulfil the heat budget.

A heat budget is a correct balance between the planet's incoming heat and the outgoing heat emitted as radiation. If the balance is disrupted, the earth will gradually warm or cool with each passing year.
