Which Of The Following Best Describes How Geysers Erupt?

Which of the following best describes how geysers erupt? With a slight reduction in pressure, water in a saturated, natural conduit suddenly boils, sending a plume of steam and hot water into the air above the vent.

Which of the following best describes what a water table is?

Explanation: The water table is the upper surface of the zone of saturation. The zone of saturation is where the pores and fractures of the ground are saturated with water. The water table is the surface where the water pressure head is equal to the atmospheric pressure.

Which of the following best describes an aquifer?

An aquifer is a body of porous rock or sediment saturated with groundwater. Groundwater enters an aquifer as precipitation seeps through the soil. It can move through the aquifer and resurface through springs and wells.

Which of the following is the best definition of a confined aquifer?

Correct answer:

A confined aquifer is a naturally occurring phenomenon where the water table is sealed by impermeable bedrock or clay. This geological phenomenon makes it impossible for the water table to recharge by precipitation or from above-ground water percolating through porous rock.

What happens after a geyser erupts?

The eruption will continue until all the water is forced out of the tube, or until the temperature inside the geyser drops below boiling (100 degrees Celsius, or 212 degrees Fahrenheit, at sea level). After the eruption, water slowly seeps back into the tube.

What erupts in a geyser quizlet?

Water boiling in the geyser system produces steam bubbles, causing expansion and overflow at the surface. With pressure suddenly reduced, water trapped in side chambers flashes into steam. The resulting “explosion clears the upper part of the geyser tubes and shoots water and steam into the air.

Which of the following best describes the distribution of water and earth?

Which of the following best describes the distribution of water on Earth? Water is evenly distributed across Earth.

What is a water table aquifer?

A water table”or unconfined”aquifer is an aquifer whose upper water surface (water table) is at atmospheric pressure, and thus is able to rise and fall.

What is a water table in construction?

A water table is a projection of lower masonry on the outside of a wall slightly above the ground. It is both a functional and architectural feature that consists of a projection that deflects water running down the face of a building away from lower courses or the foundation.

Which of the following materials would make the best aquifer?

Unconsolidated materials like gravel, sand, and even silt make relatively good aquifers, as do rocks like sandstone. Other rocks can be good aquifers if they are well fractured.

What three factors describe the movement of surface water in streams and rivers?

The stream or river’s gradient, flow, and stream load are three factors that describe the movement of surface water.

What does Q in Darcy’s law describe?

Q is the flow rate (m3/s) of the fluid flowing through the area A. The flux of fluid through A is q = Q/A. L is the length of the cylinder. “p = poutlet ” pinlet = pb ” pa. = “p/L = hydraulic gradient applied between the points a and b.

How do confined and unconfined aquifers differ?

A confined aquifer happens to be surrounded by many rock and clay pieces, but on the other hand, an Unconfined Aquifer happens to be competitively exposed to the surface of the land. A Confined Aquifer is found deep beneath the ground level, while an unconfined aquifer is found just below the ground level.

What is the best definition of a water table Quizizz?

What is the best definition of a water table? The level to which a river rises when it floods. The boundary between the land and the ocean.

What is confined aquifer and unconfined aquifer?

Unconfined aquifers are where the rock is directly open at the surface of the ground and groundwater is directly recharged, for example by rainfall or snow melt. Confined aquifers are where thick deposits overly the aquifer and confine it from the Earth’s surface or other rocks.

How geysers are formed and what causes their eruptions?

At high temperatures, groundwater dissolves more silica from the rock than it could if it was at a lower temperature. When this water reaches the surface and erupts as a geyser, the silica-rich waters cool to the surrounding temperature and evaporate.

How does a volcano erupt?

Volcanoes erupt when molten rock called magma rises to the surface. Magma is formed when the earth’s mantle melts. Melting may happen where tectonic plates are pulling apart or where one plate is pushed down under another. Magma is lighter than rock so rises towards the Earth’s surface.

Why might geysers stop erupting?

Eruptions stop when the water column in the geyser cools below the boiling point, and the process repeats. All these underground processes seem to be affected only by the heat source deep below the geyser, because they could find no evidence that the surface temperature affected eruptions.

What is a geyser quizlet?

Geyser. A fountain of hot water and steam that builds up pressure underground and erupts at regular intervals.

What are the 3 V of volcanoes?

There are three types of volcanoes: cinder cones (also called spatter cones), composite volcanoes (also called stratovolcanoes), and shield volcanoes. Figure 11.22 illustrates the size and shape differences amongst these volcanoes. Shield volcanoes, which get their name from their broad rounded shape, are the largest.

What causes the geysers and hot springs in Yellowstone?

Heat and volcanic gases from slowly cooling magma rise and warm the dense salty water that occupies fractured rocks above the Yellowstone magma chamber. That brine, in turn, transfers its heat to overlying fresh groundwater which is recharged by rainfall and snowmelt from the surface.

How does Earth distribute water?

About 71 percent of the Earth’s surface is water-covered, and the oceans hold about 96.5 percent of all Earth’s water. Water also exists in the air as water vapor, in rivers and lakes, in icecaps and glaciers, in the ground as soil moisture and in aquifers, and even in you and your dog.

How is water distributed on Earth quizlet?

Earth’s freshwater is spread out equally over ice, groundwater, and surface water. C. Most of the freshwater on Earth is found underground. The rest is stored as surface water.

How does water get distributed?

In urban and suburban areas, water is distributed from the source through large underground pipes, called water mains, under the streets. A map of the water mains in your town would look something like the pattern of branches on a tree or the pattern of tributaries in a river system.

What geologic process caused aquifers to form?

Similar to a below-ground sponge, aquifers are the natural accumulation of runoff and precipitation. Below the surface, this runoff then percolates into crevices between rocks, silt and other material.

How do underground aquifers work?
