Where is the temperature of the mantle material greater at point A or at point B?

Where is the temperature of the mantle material greater at point A or at point B?

Question Two: Where is the temperature of the mantle material greater, at point A or point B? Explain why. Point A, as the closer to the centre of the earth, the higher the temperature. Also this point is where the fluid in the convection begins to heat up, before rising to point B where it cools.

What happens to the thermal energy and density of the material between points B and C?

What happens to the temperature and density of the material between It spreads out as it co points B and C? The temperature cools and density increasas. Crust thicker as well as causes it to move.

What happens to the temperature and density of the material between points DNA?

Where is the density of the material greater, at point B or point C? What happens to the temperature and density of the material between points D and A? Heat from the core causes the temperature of the material to rise, this means the density will decrease since hotter material is less dense than cooler material. 8.

Where is the temperature of the mantle material greater and why?

The temperature of the mantle varies greatly, from 1000° Celsius (1832° Fahrenheit) near its boundary with the crust, to 3700° Celsius (6692° Fahrenheit) near its boundary with the core. In the mantle, heat and pressure generally increase with depth.

What is the density of the mantle material that is going up?

4.5 g/cm3
The mantle has a density of 4.5 g/cm3, and temperatures in the range of 1000-1500 oC. The uppermost layer of the mantle is more rigid, while the deeper regions are fluid, and it is the motion of fluid materials in the mantle that is responsible for plate tectonics (see section 4.3).

What plate motion is happening at point B?

What happens at point B in a convection current? The magma is rising towards the Lithosphere. It hits the hard Lithosphere and either turns left or right. It can not continue through the Lithosphere.

When thermal energy is increased in a solid What change in state is happening?

melting
When thermal energy is added to a substance, its temperature increases, which can change its state from solid to liquid (melting), liquid to gas (vaporization), or solid to gas (sublimation).

What happens to the density of a fluid as it temperature increases decreases?

Answer:In general, the liquids tend to expand when their temperature increases. For example, the same mass of boiling water occupies more volume at 100 degrees Celsius than at 20 degrees Celsius. Therefore, increasing temperature decreases density.

Where is the temperature of the mantle material greater at point B or point C Explain why?

Temperature is greater at point A because it is closer to center of the Earth. Also, this is where the rock of the mantle gets hot enough to rise up towards point B, due to a change in temperature and density.

Is the temperature of the magma greater at point B or point A?

The temperature of the magma is greater at point A because it is closer to the Inner Core, the heat source.
