Friction . The space craft is moving at several thousands of miles per hour (extremely fast) . At this speed it meets up with the gas particles of the upper atmosphere, hence friction.
As an anology, if you throw a spinning flat stone parallel to the surface of water it will bounce off the water. If that angle is too big that stone will plunge into the water causing a splash (friction).
So space capsules have to strike the upper atmosphere at just the correct angle, because '1' they may bounce off into space and never return, or '2' plunge so sharply into the atmosphere that they 'burn' up.
So the angle of re-entry has to be 'just right' to stop either 'bouncing off' or creating a 'big splash'. Thereby minimising friction.
The process by which water returns to the land from the atmosphere is called precipitation. This includes rain, snow, sleet, or hail falling from clouds in the sky back to the Earth's surface.
Evaporation is the process by which water returns to the atmosphere from land surfaces such as rivers, lakes, and soil. Transpiration is the process by which water vapor is released into the air from plants through their leaves.
The moisture that returns to Earth is called precipitation. This includes rain, snow, sleet, or hail that falls from the atmosphere to the ground.
Water returns to the atmosphere through a process called evaporation. When the sun heats up water bodies like lakes, rivers, and oceans, the water molecules gain enough energy to change into water vapor and rise into the air. This water vapor eventually cools and condenses into clouds, which then release precipitation back to the Earth as rain or snow.
The process of evaporation moves water from the Earth's surface to the atmosphere, where it condenses into clouds. Precipitation, such as rain or snow, returns water from the atmosphere to the Earth's surface. This cycle is known as the water cycle.

friction
As the space capsule re-enters Earth's atmosphere, it experiences immense friction with the air, causing the exterior to heat up rapidly. This intense heat leads to the glow, heating up the exterior to temperatures hot enough to emit a red glow. Heat shields are used to protect the spacecraft and its occupants from these extreme temperatures.

The process that returns water to the atmosphere in an ecosystem is evaporation. Water from sources such as lakes, rivers, and oceans is heated by the sun, turning it into water vapor that rises into the atmosphere.
Evaporation.
Just as the Earth's Nitrogen cycle and its Carbon cycle are cyclic, the Earth's Water Cycle is just that; Water Vapor returns to the Atmosphere to complete the Cycle.
The command module was the only part of the Apollo mission spacecraft that returned to Earth. It housed the astronauts and was designed to re-enter the Earth's atmosphere and splash down safely in the ocean.
