How does the hydrologic cycle water cycle impact life on Earth?
The water cycle on Earth Water is essential to life on Earth. Liquid water flows across land (runoff), into the ground (infiltration and percolation), and through the ground (groundwater). Groundwater moves into plants (plant uptake) and evaporates from plants into the atmosphere (transpiration).
What are the negative effects of human activities on resources?
Humans impact the physical environment in many ways: overpopulation, pollution, burning fossil fuels, and deforestation. Changes like these have triggered climate change, soil erosion, poor air quality, and undrinkable water.
Why is the hydrologic cycle important to life on Earth?
The hydrologic cycle is important because it is how water reaches plants, animals and us! Besides providing people, animals and plants with water, it also moves things like nutrients, pathogens and sediment in and out of aquatic ecosystems.
Why is learning about the water cycle important?
The water cycle is an important process that recycles water and nutrients. In doing so, it brings freshwater to people, animals and plants all around the world. The water cycle begins with the ocean, lakes, ponds and other bodies of water on earth.
How does the water cycle affect the environment?
Through the water cycle, heat is exchanged and temperatures fluctuate. As water evaporates, for example, it absorbs energy and cools the local environment. As water condenses, it releases energy and warms the local environment. The water cycle also influences the physical geography of the Earth.
How is the water cycle powered by the Sun?
The water, or hydrologic, cycle describes the pilgrimage of water as water molecules make their way from the Earth’s surface to the atmosphere and back again, in some cases to below the surface. This gigantic system, powered by energy from the Sun, is a continuous exchange of moisture between the oceans, the atmosphere, and the land.
