Answer:
light is required to provide energy for photosynthesis
Explanation:
For photosynthesis to take place, it requires the presence of light and chlorophyll. The process has two stages; light and dark stage.
In the light stage, chlorophyll molecules absorb light energy which is used to split water molecules into oxygen and hydrogen atoms. The process is called photolysis.
water→ hydrogen atoms + oxygen.
The hydrogen atoms produced enter the dark stage while oxygen is released in the atmosphere. In the dark stage, carbon dioxide combines with the hydrogen atoms to form simple sugar such as glucose.
<span>Earth rotates around its axis and also revolves around the Sun. Rotation is the motion that causes day and night. Earth completes one full rotation every 24 hours. The part of the Earth that faces the Sun has day and the other part has night.</span>
If the molecules in a gas lose energy, they will move closer together and change phase into a liquid
Explanation:
Condensation is process where matter changes his states from one to another. In evaporation, matter changes from liquid to gas but when matter changes from gas to liquid is known as condensation. It exists in the form of heat.
The example of condensation of water drops outside the glass. It happens when molecule become cool. Here molecule lose heat. Here it loses its temperature or heat and become slow down
