Do convection currents form in the mantle when heated materials become more dense?
Actually, heated materials are less dense. When heat is applied to a substance such as liquid, it becomes less dense. It is this less dense and heated material that rises because it weighs less. The part of the mantle that is more dense would be any substance that is cooling and is sinking down.
Shrinkage percentage of rubber when heated and cooled?
when rubber is moulded in die and kept for heat after few min the die is removed from heat... the ruber reduces its size compare to original size of die ... its called srinkage of rubber... this srinkage in rubber have different percentage of srinkage in different types of rubber....
Is television violence a social problem?
Television violence can be a social problem as it can contribute to increased aggression, desensitization to violence, and negative behavioral outcomes, especially in children and adolescents. It is essential for media producers to consider the impact of violent content on viewers and for parents to monitor and regulate their children's exposure to such material.
Is a smithy a workshop for a blacksmith?
Yes a smithy is the name for a blacksmiths workshop.
Why does my boyfriend block me when he's mad?
Your boyfriend may block you when he's mad as a way to create space and distance during a heated moment. This action could be a way for him to cool off and avoid saying or doing something hurtful in the heat of the moment. Communication and understanding each other's boundaries can help address this behavior in a healthy way.

What is transfer of heat by the movement of matter?
Convection is the transfer of heat by the movement of a fluid or gas. This occurs because the heated material becomes less dense and rises, while the cooler material sinks. Convection is responsible for processes such as weather patterns and the movement of magma in the Earth's mantle.
Does mantle material rise in convection currents because heated materials become more dense?
no
What does density have to do with convection?
Things with a lower density will float on things with a higher density. If you take a fluid (air or water) and heat it, the portion that is heated usually expands. The same mass takes up more volume and as a consequence the heated portion becomes less dense than the portion that is not heated. Get it? Hope you do!
What does air do when it is heated in convection?
When air is heated in convection, it becomes less dense and rises. As it rises, it displaces cooler air, which then becomes heated and rises as well. This creates a continuous cycle of warm air rising and cool air sinking, which is known as convection.
Why does the material in the asthenosphere rise as it is heated?
The material in the asthenosphere rises when heated because of its reduced density. As it absorbs heat, the material becomes less dense compared to the cooler surrounding rocks. This buoyant force causes the heated material to rise towards the surface.
When heat energy travels by convection energy is transferred by the circulation of heated material?
Yes, when heat travels by convection the energy is transferred by the circulation of a heated fluid, such as air or water.
What are the main causes of convection in the asthenosphere?
The main causes of convection in the asthenosphere are heat generated from the Earth's core, radioactive decay of elements within the Earth, and the movement of tectonic plates. As the material in the asthenosphere is heated unevenly, it becomes less dense and rises, while cooler, denser material sinks, creating a convection current.
Water being heated in a pan circulates because of?
convection - as the water near the heat source gets warmer, it becomes less dense and rises, creating a current that circulates the water in the pan.
What is the movement in both the Earth's engines of heated material upward and cooled material downward an example of?
convection current
What is the transfer of thermal energy by movement of heated matter?
Convection is the transfer of thermal energy by the movement of heated matter, such as air or water. This process occurs as warmer, less dense material rises and cooler, denser material sinks, creating a convection current that transfers heat.
The motion created when heated material continually rises cools and sinks?
Convection current
