What are the two sources of energy for the Earth system? the sun, which drives external processes, and the Earth's rotation, which drives internal processes the revolution of the Earth along its orbit:which drives external processes, and the Earth's rotation, which drives internal processes the shin, which drives external processes, and heat inside the Earth, which drives internal processes the sun, which drives external processes, and the Earth's rotation, which drives both exter-nal and internal processes

## Step 1<br />The Earth system is primarily powered by two sources of energy: the sun and the heat inside the Earth. <br /><br />## Step 2<br />The sun provides the energy that drives external processes on Earth. This includes processes such as photosynthesis in plants, the water cycle, and the climate system. The sun's energy is essential for life on Earth and plays a significant role in shaping the planet's environment.<br /><br />## Step 3<br />The Earth's internal heat, generated by the decay of radioactive elements and the residual heat from the planet's formation, drives internal processes. This includes plate tectonics, volcanic activity, and the geothermal gradient. These processes are crucial for shaping the Earth's surface and influencing the planet's climate and habitability.<br /><br />## Step 4<br />The Earth's rotation does play a role in the distribution of heat around the planet and in the formation of weather patterns, but it is not a primary source of energy for the Earth system.<br /><br />## Step 5<br />The Earth's revolution along its orbit does not provide a significant source of energy for the Earth system. The primary source of energy during the Earth's revolution is the sun.
