What is it called when liquid water is heated up by the sun and becomes a gas or vapor?
Evaporation happens when a liquid turns into a gas. It can be easily visualized when rain puddles “disappear” on a hot day or when wet clothes dry in the sun. In these examples, the liquid water is not actually vanishing—it is evaporating into a gas, called water vapor. Evaporation happens on a global scale.
What is the role of the sun in the water cycle?
The sun is what makes the water cycle work. The sun provides what almost everything on Earth needs to go—energy, or heat. Heat causes liquid and frozen water to evaporate into water vapor gas, which rises high in the sky to form clouds… clouds that move over the globe and drop rain and snow.
What happens to water vapor as it rises over the mountain?
The orographic effect occurs when air masses are forced to flow over high topography. As air rises over mountains, it cools and water vapor condenses.
What is it called when water vapor up in the sky becomes liquid water?
Condensation is the process by which water vapor in the air is changed into liquid water.
What happens to a liquid when heated?
When a liquid is heated, it turns to its gaseous state (or converted into vapour).
Which form of energy from the sun is needed for the water cycle?
The water cycle is the process that water moves through between the air and Earth’s surface. The water cycle is powered by heat energy from the Sun. A cycle is like a circle—it has no beginning and no end.
What is the role of the sun?
The sun has extremely important influences on our planet: It drives weather, ocean currents, seasons, and climate, and makes plant life possible through photosynthesis. Without the sun’s heat and light, life on Earth would not exist.
What is characteristics of liquid?
Liquids have the following characteristics: No definite shape (takes the shape of its container). Has definite volume. Particles are free to move over each other, but are still attracted to each other.
What are 5 characteristics of liquids?
liquid have a fixed volume but no fixed shape.
What is precipitation and condensation?
Definitions. condensation:transition from vapor phase to liquid phase. precipitation: deposition of liquid water droplets and ice particles that are formed in the atmosphere and grow to a sufficient size so that they are returned to the Earth’s surface by gravitational settling. Solid and liquid.
When water vapor changes to liquid and falls on land such as rain snow sleet or hail?
Precipitation is any liquid or frozen water that forms in the atmosphere and falls back to the Earth. It comes in many forms, like rain, sleet, and snow. Along with evaporation and condensation, precipitation is one of the three major parts of the global water cycle.
What happens to a liquid?
If a liquid is heated the particles are given more energy and move faster and faster expanding the liquid. The most energetic particles at the surface escape from the surface of the liquid as a vapour as it gets warmer. Liquids evaporate faster as they heat up and more particles have enough energy to break away.
What liquids expand when heated?
Water, like most other liquids, expands when heated and contracts when cooled, except in the temperature region between 32°F (0°C) and 39.2°F (4°C).
What happens to water in the sun?
When water at the ocean’s surface is heated by the Sun it gains energy. With enough energy, the molecules of liquid water change into water vapor and move into the air. This process is called evaporation.
How energy is produced in sun?
Solar energy is created by nuclear fusion that takes place in the sun. Fusion occurs when protons of hydrogen atoms violently collide in the sun’s core and fuse to create a helium atom. This process, known as a PP (proton-proton) chain reaction, emits an enormous amount of energy.
What is energy from the sun called?
Solar radiation, often called the solar resource or just sunlight, is a general term for the electromagnetic radiation emitted by the sun. Solar radiation can be captured and turned into useful forms of energy, such as heat and electricity, using a variety of technologies.
Why is it important to get sunshine?
Sunlight is essential for human health and well-being. The health benefits of sunlight include generating the production of vitamin D, supporting bone health, lowering blood pressure, preventing disease, and promoting good mental health.
