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.
What else can I help you with?
Convection occurs because heated material becomes what?
Convection occurs because heated material becomes less dense and rises, while cooler, denser material sinks. This creates a circular motion of fluid or air to transfer heat.
Is a smithy a workshop for a blacksmith?
Yes a smithy is the name for a blacksmiths workshop.
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....
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.
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.
Does mantle material rise in convection currents because heated materials become more dense?
no
What is the liquid in the pot is being heated by?
Convection currents from the stove or microwave.
How is air heated near the earths surfaces?
It's heated through the convection currents.
Can you use convection in a sentence?
Convection currents in the Earth's mantle drive the movement of tectonic plates, resulting in earthquakes and volcanic activity.
Which diagram correctly indicates why convection currents form in water why water is heated?
which diagram correctly indicates why convection currents form in water when water is heated
Why cant convection currents form if they are heated from the top?
Convection currents form when a fluid is heated from the bottom, causing it to rise and create a circulating flow. If a fluid is heated from the top, there is no temperature difference to drive the circulation, preventing convection currents from forming. Heat needs to be applied at the bottom to induce the necessary buoyancy-driven flow for convection currents to occur.
What will happens to convection currents when liquid or gas is no longer heated?
When a liquid or gas is no longer heated, the heat source that drives convection currents is removed. As a result, the temperature differential that causes the fluid to circulate diminishes, and eventually the convection currents will slow down and stop as the fluid reaches thermal equilibrium.
If a pot is no longer heated when will the convection currents stop flowing?
Once the pot is no longer heated, the temperature of the liquid inside will begin to stabilize and the convection currents will gradually slow down and eventually stop as the temperature equalizes throughout the liquid.
How do you slow convection?
To slow convection, you can use insulation to reduce heat transfer by convection. This can involve using materials such as foam, fiberglass, or reflective barriers to trap heat. Additionally, you can create barriers or partitions to block air currents and inhibit the circulation of heated air.
What happends to convection currents when the liquid or gas is no longer heated?
It falls back down
What currents can form when liquids and gases are heated?
When liquids and gases are heated, they can create convection currents. In liquids, heated areas become less dense and rise, while cooler areas sink, creating a circular flow. In gases, heated air rises and cooler air sinks, generating vertical movements that mix and distribute heat.
Is it true molten material in the asthenosphere rises in convection currents because heated materials become more dense?
Actually, hot, less dense material rises, and cold, denser material sinks. Denser material will be heavier (per unit volume) and gravity therefore pulls it down. Less dense material has buoyancy and rises. It's very logical.
