EVERYDAY SCIENCE

Detailed explanation-1: -The water cycle is driven primarily by the energy from the sun. This solar energy drives the cycle by evaporating water from the oceans, lakes, rivers, and even the soil. Other water moves from plants to the atmosphere through the process of transpiration.

Detailed explanation-2: -Heat from the sun evaporates water from the oceans. Water rises into the air as vapor and travels with the wind. If the air begins to cool-such as when air warmed by the Earth’s surface rises or when wind drives air up and over mountains-the air loses its ability to hold water.

Detailed explanation-3: -In the water cycle, evaporation occurs when sunlight warms the surface of the water. The heat from the sun makes the water molecules move faster and faster, until they move so fast they escape as a gas. Once evaporated, a molecule of water vapor spends about ten days in the air.

Detailed explanation-4: -Energy from the Sun causes water in the oceans to evaporate. The water vapor rises into the air. The salts remain behind.

Detailed explanation-5: -Energy from the sun causes water on the surface to evaporate into water vapor – a gas. This invisible vapor rises into the atmosphere, where the air is colder, and condenses into clouds. Air currents move these clouds all around the earth.
