Thrust acts on the spacecraft and propels in the space.
<h3>How space shuttles move?</h3>
1. The force created by the shuttle's engines in expelling the burning fuel produces an equal thrust in the opposite direction. This thrust acts on the spacecraft and propels in the space.
2. The thermosphere and the stratosphere are our hottest atmosphere layers because these two layers are present near the sun as compared to other layers of atmosphere.
3. When the meteors hit the atmosphere, meteors rub against air particles and create friction which is heating the meteors. The heat vaporizes most meteors, creating what we call shooting stars.
Animals get the nitrogen they need by eating plants or other animals that contain nitrogen. When organisms die, their bodies decompose bringing the nitrogen into soil on land or into ocean water. Bacteria alter the nitrogen into a form that plants are able to use.
