When the heat source is removed from a fluid convection currents in the fluid will a speed up B change direction C eventually stop D continue at the same rate forever?

When the heat source is removed from a fluid convection currents in the fluid will a speed up B change direction C eventually stop D continue at the same rate forever?

Explanation: As the heat source gets removed from the fluid then the convection currents in the fluid will eventually slow down and then get stopped. The convection current moving in the fluid will create a high temperature and density difference. And this will leads to the energy transfer will then decrease.

When the heat source is applied to fluid convection currents in the fluid will?

Answer. The heat energy can be transferred by the process of convection by the difference occurring in temperature between the two parts of the fluid. Due to this temperature difference, the hot fluids tend to rise, whereas cold fluids tend to sink. This creates a current within the fluid called Convection current.

What happens to the convection current when the heat source is applied to it?

Convection currents form because a heated fluid expands, becoming less dense. The less-dense heated fluid rises away from the heat source. As it rises, it pulls cooler fluid down to replace it. This fluid in turn is heated, rises and pulls down more cool fluid.

What happens to convection currents when the liquid or gas is no longer heated?

What happens to convection currents when the liquid or gas is no longer heated? The heat changes the fluids density. They slow down and stop.

What will happen to a convection current If there is no more heat added?

Without heat, the convection currents will eventually stop when all of the material has reached the same temperature.

What are the causes and effects of convection currents?

convection currents occur when a heated fluid expands, becoming less dense, and rises. The fluid then cools and contracts, becoming more dense, and sinks….

How does temperature change create convection currents?

When the molecules are heated, they move faster and move apart, causing them to be less dense and rise. When the warm air rises and the cool air sinks, convection currents are created. Since gas molecules are not visible, it is hard to imagine convection currents.

How does heat move in convection?

Convection occurs when particles with a lot of heat energy in a liquid or gas move and take the place of particles with less heat energy. Heat energy is transferred from hot places to cooler places by convection. In this way, convection currents that transfer heat from place to place are set up.

Why do convection currents move in a circular motion?

Convection currents are circular patterns that move air and liquids as a result of unequal heating and cooling. Hot air rises because it is less dense and then sinks as it cools.

What are the steps of convection currents?

Put the following steps of the convection process in the correct…

• Gravity pulls cooler matter downward.
• The matter expands and decreases in density.
• An up-and-down flow of matter produces a convection current.
• Matter is heated.
• Warmed matter is forced upward.

What happens when magma convection currents move in opposite directions?

Answer: During the “magma convection currents”, the plate tectonics are pulled apart from each other. This is because if the “magma convection currents” flow in opposite direction, the plates present floating on the molten magma also float apart, causing divergent plate boundaries….

Which step is not part of a normal convection cycle?

One step that is not part of a normal convection cycle is, warmed air rises, creating a high-pressure system….

How are convection currents important to the earth?

Convection currents play a role in the circulation of fluids. Convection currents are the result of differential heating. Inside Earth, the convection of mantle material is thought to cause the movement of the overriding crustal plates, resulting in events such as earthquakes and volcanic eruptions.

How fast do convection currents in the mantle move?

These plates move very slowly across the surface of the Earth as though they were on a conveyor belt. The convection currents in the much hotter mantle continually move the plates about 1/2 to 4 inches per year.

What causes tectonic plates to move?

The heat from radioactive processes within the planet’s interior causes the plates to move, sometimes toward and sometimes away from each other. This movement is called plate motion, or tectonic shift….

What are three causes of plate movement?

In this lesson, we explore the causes of plate movement, including thermal convection, ridge push and slab pull. Students will learn how these processes complement each other and form a theory for tectonic plate movement.

How fast do tectonic plates move?

They move at a rate of one to two inches (three to five centimeters) per year.

How do tectonic plates affect us?

Plate tectonics affects humans in several important ways. What would Earth be like without plate tectonics? We’d have many fewer earthquakes and much less volcanism, fewer mountains, and probably no deep-sea trenches. In other words, the Earth would be a much different place.

What are the major causes and effects of tectonic plate movements?

They have also caused faults, cracks in the earth’s crust. Shifts along a fault can also cause earthquakes or violent jolts in the area around it. In coastal areas undersea earthquakes can cause huge waves known as Tsunamis to erupt. Plate tectonics cause folding of rock layers into mountains.

What will happen if Earth has no tectonic plates?

Over millions of years, continents drift across Earth’s surface, going from one climate zone to another. Without plate tectonics, Earth would not have its diverse geography, which provides a wide range of habitats. Plate tectonics is also responsible for hydrothermal vents on the ocean floor….

What is the importance of studying tectonic plates?

Plate tectonics revolutionized the way geologists view Earth. This new paradigm brings together nearly all the divisions of geologic study. Like the theory of evolution in biology, plate tectonics is the unifying concept of geology.

What would happen if a tectonic plate broke?

The Earth’s crust is broken into plates that are in constant motion over timescales of millions of years. When the latter plates break apart, a plume of hot rock can rise from deep within the Earth’s interior, which can cause massive volcanic activity on the surface….

Is plate tectonics essential for life?

Plate activity on Earth has helped to regulate the level of carbon dioxide over the eons. The same weathering that pulls nutrients from mountaintops down into the oceans also helps to remove carbon dioxide from the atmosphere. The Alaska Range continues to grow today as a result of plate tectonics….

What are the 3 theories of plate tectonics?

Plates interact at three types of plate boundaries: divergent, convergent and transform. Most of the Earth’s geologic activity takes place at plate boundaries. At a divergent boundary, volcanic activity produces a mid ocean ridge and small earthquakes.
