- The driving force for the hydrologic cycle is the sun, which provides the energy needed for evaporation like the flame for a gas stove gives the energy for water to boil water… and make steam. Water changes from a liquid state to a gaseous state as it evaporates from the oceans, lakes, streams, and soil.

Biological processes depend on energy flow through the Earth system. The Sun is the primary source of energy for nearly all biological systems. Sunlight allows plants, algae and cyanobacteria to use photosynthesis to convert carbon dioxide and water into organic compounds like carbohydrates. This process is the fundamental source of organic material in the biosphere.

- Urbanization and the Water Cycle 4 Water Cycle Before Urbanization UNCE The Water Cycle Before Urbanization The hydrologic or water cycle transports water between earth’s land, atmosphere, and oceans. The major processes moving water are evaporation, transpiration, condensation, and precipitation. Evaporation occurs when the sun’s energy turns liquid water on the earth’s surface into water vapor, which enters the atmosphere. Water vapor leaves plants in a process called transpiration.

Water Cycle and Precipitation The driving force of precipitation and the water cycle in general is the solar energy from the Sun. Earth maintains a delicate balance of radiative energy by reflecting approximately one third of the incoming solar radiation, and emitting the remaining two-thirds that are absorbed as infrared radiation back to space.

How Evaporation & Transpiration Contribute to the Hydrologic Cycle Evaporation and transpiration are two other critical components of the water cycle because they are the processes that put water into the atmosphere in the first place. We'll explore each more in detail in this lesson, but it's important to keep in mind that the water cycle is not circular, like running around a track.

Water Cycle The hydrologic cycle describes the pilgrimage of water as water molecules make their way from the Earth's surface to the atmosphere, and back again. This gigantic system, powered by energy from the sun, is a continuous exchange of moisture between the oceans, the atmosphere, and the land.

The Water Cycle: Evaporation Evaporation from the oceans is the primary mechanism supporting the surface-to-atmosphere portion of the water cycle. After all, the large surface area of the oceans (over 70 percent of the Earth's surface is covered by the oceans) provides the opportunity for large-scale evaporation to occur.

Teaching Essential Principle One Solar radiation is the fundamental energy driving our climate system, and nearly all climatic and biologic processes on Earth are dependent on solar input. Energy from the sun is essential for many processes on Earth including warming of the surface, evaporation, photosynthesis and atmospheric circulation.

What major driving force behind winds, ocean currents, and the global water cycle is? Solar energy drives all of the factors that you mentioned. The sun's heating causes evaporation of water from the ocean. The sun's heating at the equator causes the changes in density that result in currents. The sun's heating of the atmosphere causes the changes in air temperature that change the density of the air that result in winds. Sydney D · 6 years ago.

Physical processes on Earth are the result of energy flow through the Earth system. These flows of energy are often overlooked but in many senses energy transfer can be thought of as a the driving force of the Earth system. This principle points out that most of the energy in the Earth system comes from just a few sources: solar energy, gravity, radioactive decay and the rotation of the Earth.

Water cycle The water cycle is powered from solar energy. 86% of the global evaporation occurs from the oceans, reducing their temperature by evaporative cooling. Without the cooling, the effect of evaporation on the greenhouse effect would lead to a much higher surface temperature of 67 °C (153 °F), and a warmer planet.
