Science Lesson Plan Quiz

Rain comes from clouds because clouds are formed when warm air rises and cools, causing water vapor to condense into tiny droplets. These droplets then combine and grow in size, eventually becoming too heavy for the cloud to hold, resulting in rainfall. Therefore, clouds are the source of rain.

Heat causes water to evaporate. When water is heated, the energy from the heat causes the water molecules to gain enough kinetic energy to break the hydrogen bonds holding them together. This allows the water molecules to escape from the liquid phase and enter the gaseous phase as water vapor. This process is known as evaporation. Condensation, on the other hand, occurs when water vapor cools down and loses energy, causing the water molecules to come together and form liquid water droplets.

In a hot environment, the rainwater tends to evaporate. This is because the high temperature causes the water molecules to gain energy and transform from a liquid state to a gaseous state. As a result, the rainwater disappears into the atmosphere as water vapor.

The Pacific Ocean is the correct answer because it is the largest body of water on Earth. It covers a vast area, stretching from the western coast of North and South America to the eastern coast of Asia and Australia. The Pacific Ocean is approximately twice the size of the Atlantic Ocean and contains numerous islands, deep trenches, and diverse marine life. It is known for its immense size and significant role in global climate patterns.

Rain clouds are formed through a process called evaporation and condensation. When the sun heats up the surface of the ocean, the water molecules turn into water vapor and rise into the air. As the warm air rises, it cools down and the water vapor condenses, forming tiny droplets. These droplets then combine and form clouds. Eventually, the droplets become too heavy to stay suspended in the air, leading to precipitation in the form of rain. Therefore, the correct answer is "From the ocean."
