How are the properties of water important to the planets dynamics?
These properties include water's exceptional capacity to absorb, store, and release large amounts of energy as it changes state; to transmit sunlight; to expand upon freezing; to dissolve and transport many materials; and to lower the viscosities and freezing points of the material when mixed with fluid rocks in the …
Why is water important to life quizlet?
It is important for life because the water that covers the Earth keeps the temperature functioning on land that permits life. Additionally, all organisms are made up of water which enables more resistance in the change of temperature than if they were made of liquid with a lower specific heat.

What are the special properties of water and why are they important quizlet?
Polarity, Hydrogen bonding, Adhesive, Cohesion, and the ability to moderate temperature and expanding upon freezing and as a solvent. Because of the angles of its chemical bonds, the oxygen atom is on one end of the molecules and the hydrogen atoms are on the other.
Why is water important to life biology quizlet?
It is important for life because the water that covers the Earth keeps the temperature functioning on land that permits life. Additionally, all organisms are made up of water which enables more resistance in the change of temperature than if they were made of liquid with a lower specific heat.
Which is one way that water helps living things quizlet?
– Water in plants and animals transports nutrients into cells. – Water reflects sunlight that hits the oceans. – Water builds up rock and soil.
Why is water so important to life quizlet?

How do living things contribute to the water cycle quizlet?
How do animals assist in the water cycle? Animals lose water by sweating and urination. These are both evaporated, adding water vapor to the atmosphere. When animals respire, water is produced and water vapor is given off.
What’s one way in which water helps maintain homeostasis in an organism?
Water is an essential feature of homeostasis in an organism. Water increases the volume of blood, which affects blood pressure and heart rate. Water dissolves gases and allow for efficient exchange and transport of oxygen and carbon dioxide.
What are three important properties of water that support life on Earth?
Discussion of the properties of water that make it essential to life as we know it: polarity, "universal" solvent, high heat capacity, high heat of vaporization, cohesion, adhesion and lower density when frozen.
Why is the cohesion of water important to life?
These cohesive and adhesive properties are essential for fluid transport in many forms of life. For example, they allow nutrients to be transported to the top of a tree against the force of gravity. Water is less dense as a solid than as a liquid.
How living things contribute to the water cycle?
Plants, especially trees, contribute to the water cycle via transpiration, where water evaporates from the surface of their leaves. Close to 10 percent of all water enters the water cycle due to plant transpiration. Animals contribute to the water cycle via respiration, perspiration and urination.
Why is precipitation important to the water cycle?
Why is Precipitation Important? Precipitation is needed to replenish water to the earth. Without precipitation, this planet would be an enormous desert. The amount and duration of precipitation events affect both water level and water quality within an estuary.
