C why we will happen if earth stop rotating
Answers
Explanation:
A. You may yawn is because the body wants to wake itself up. The motion helps stretch the lungs and their tissues, and it allows the body to flex its muscles and joints. It may also force blood toward your face and brain to increase alertness.
B. Light helps you know when to sleep and when to be awake. When you open your eyes in the morning, sunlight lets your brain know it is time to wake up. As day turns to night, your brain makes a chemical called melatonin (mel-a-TONE-in) that makes you sleepy.
C. If the Earth were to stop spinning on its axis, gradually the oceans would migrate towards the poles from the equator. ... You could travel around the Earth on the equator and stay entirely on dry land—ignoring the freezing cold on the night side, and the searing heat on the day side.
