What is the role of gravity in the water cycle quizlet?
Consists of the same liquids that are drawn to the atmosphere through evaporation. Gravity draws that water vapor back down to the earth's surface as rain, snow, sleet, and dew.
What roles do density and gravity play in the water cycle?
It pulls precipitation down from clouds and pulls water downhill. Gravity also moves air and ocean water. Cool, dry air is denser than warm, humid air, and cool, salty water is denser than warm, less salty water. Gravity pulls denser air and water downward, forcing less dense air and water to move upward.
What is gravity water quizlet?
GRAVITY SYSTEM. Water supply system that relies entirely on the force of gravity to create pressure and cause water to flow through the system.
What is the driving force of the water cycle quizlet?
Terms in this set (12) The SUN is the driving force behind this stage of the water cycle. The SUN heats up the water, allowing some molecules to gain enough energy to undergo a phase change from a liquid to a gas. The SUN is the driving force behind this stage of the water cycle.
Why gravity plays the important role in movement?
Gravity plays an essential role in terrestrial locomotion. Due to gravity we can hit the ground without losing contact with it. However, because of gravity, work has to be done each step to lift the body even when moving on a level surface.
How does gravity keep water on Earth?
On the “near” side of the Earth (the side facing the moon), the gravitational force of the moon pulls the ocean's waters toward it, creating one bulge. On the far side of the Earth, inertia dominates, creating a second bulge. In this way the combination of gravity and inertia create two bulges of water.
What is the specific gravity quizlet?
Specific gravity is the "heaviness" of a mineral. It is defined as a number that expresses the ratio between the weight of a mineral and the weight of an equal volume of water. Water has a specific gravity of "1."
What is capillary water quizlet?
Capillary Water: Water held by the surface forces soil particles and water molecules as films around soil particles which moves from thicker to thinner films or along moisture gradients. Capillary water is the only important source of water for our cultivated plants.
What is the main driving force in the water cycle?
Energy from the sun and the force of gravity drive the continual cycling of water among these reservoirs. As the water is heated, it changes state from a liquid to a gas. This process is called evaporation. As more energy is added to the water, the water molecules move faster and farther apart.
What drives the movement of the water cycle?
The sun, which drives the water cycle, heats water in the oceans. Some of it evaporates as vapor into the air. Rising vapor cools and condenses into clouds. Cloud particles grow and fall out of the sky as precipitation.
How does gravity keep water on earth?
On the “near” side of the Earth (the side facing the moon), the gravitational force of the moon pulls the ocean's waters toward it, creating one bulge. On the far side of the Earth, inertia dominates, creating a second bulge. In this way the combination of gravity and inertia create two bulges of water.
How does gravity work?
The reason gravity pulls you toward the ground is that all objects with mass, like our Earth, actually bend and curve the fabric of the universe, called spacetime. That curvature is what you feel as gravity.
Does gravity hold water?
Gravity is the force of attraction between two objects and Earth's gravity pulls matter downward toward its center. It pulls precipitation down from clouds and pulls water downhill. Gravity also moves air and ocean water. … Gravity pulls denser air and water downward forcing less dense air and water to move upward.
What is gravity and why is it important?
The answer is gravity: an invisible force that pulls objects toward each other. Earth's gravity is what keeps you on the ground and what makes things fall. Anything that has mass also has gravity. Objects with more mass have more gravity.
What is the specific gravity of water?
1 Water has a specific gravity equal to 1. Materials with a specific gravity less than 1 are less dense than water, and will float on the pure liquid; substances with a specific gravity more than 1 are more dense than water, and will sink.
What is the difference between exact counted and inexact measured numbers quizlet?
What's the difference between exact and inexact numbers. An exact number results from counting objects or is part of a definition. An inexact number results from a measurement or observation and contains some uncertainty.
How does saturated hydraulic conductivity vary with soil texture?
Saturated hydraulic conductivity is affected by both soil and fluid properties. It depends on the soil pore geometry as well as the fluid viscosity and density. The hydraulic conductivity for a given soil becomes lower when the fluid is more viscous than water.
What are the three driving forces of the water cycle?
The water cycle consists of three major processes: evaporation, condensation, and precipitation. Evaporation is the process of a liquid's surface changing to a gas. In the water cycle, liquid water (in the ocean, lakes, or rivers) evaporates and becomes water vapor.
What are the two factors that drive the water cycle?
Explanation. The two main factors that drive the water cycle are: the energy of the Sun and the gravitational force ‾ text{underline{the energy of the Sun and the gravitational force}} the energy of the Sun and the gravitational force.
What four factors affect the steps of the water cycle?
So how can we understand this magical process called the water cycle? There are four main parts to the water cycle: Evaporation, Convection, Precipitation and Collection.
What is the importance of gravity?
Gravity keeps the Earth in orbit around the sun and keeps us warm. Gravity also keeps the water on the Earth, its inhabitants, and the atmosphere in its place. Gravity pulls rain and snow down to our rivers. Gravity permits us to move easily on earth.
How does gravity keep water down?
1 Expert Answer Gravity is a force that doesn't distinguish between object but acts on all objects on the earth equally. The same force that keeps us on earth, instead of floating off into space, uses the same magnitude of force to press down on water in oceans, lakes, and rivers.
How much gravity is there in water?
Because water at 4 degrees Celsius is the standard scientists use to determine specific gravity, it follows that its specific gravity is 1. However, a water sample at a different temperature or pressure or one containing impurities has a density that differs slightly.
How do you explain gravity to a child?
2:033:11Defining Gravity: Crash Course Kids #4.1 – YouTubeYouTube
What is the importance of specific gravity?
Measurement of specific gravity provides information regarding a patient's state of hydration or dehydration. It also can be used to determine loss of renal tubular concentrating ability. There are no "abnormal" specific gravity values. This test simply indicates urine concentration.
What is the specific gravity of water quizlet?
The specific gravity of water is 1.00. An object with a specific gravity of 3.71 (with respect to water) will sink in water. Iron has a specific gravity of 7.8 while mercury has a specific gravity of 13.6.
How many digits are not known with certainty in a number written with the proper number of significant figures?
The first zero is known with certainty and the final zero while not known with certainty is still significant. Thus, 4.000 has 4 significant figures. RULE #4 – A zero used to fix a decimal point is never significant.
Which of the following is the correct rule for significant figures in addition and subtraction?
Your answer cannot be MORE precise than the least precise measurement. For addition and subtraction, look at the decimal portion (i.e., to the right of the decimal point) of the numbers ONLY. Here is what to do: 1) Count the number of significant figures in the decimal portion of each number in the problem.
What is permeability coefficient?
The coefficient of permeability (K) is the velocity in meters or centimeters per second of water through soils. Fine-grained soils such as clays might have values of around 10-8meters/sec or lower, or a sand and gravel formation could be 10-4meters/sec or higher.
What is hydraulic conductivity in geology?
In theoretical terms, hydraulic conductivity is a measure of how easily water can pass through soil or rock: high values indicate permeable material through which water can pass easily; low values indicate that the material is less permeable.
