Why are mantle rocks solid even though the Earth's interior temperature is very hot?
The melting temperature of materials is dependent on the pressure that is applied, whereby the higher the pressure, the higher the melting temperature. As such the rocks in the mantle are experiencing such a high pressure, that their melting point is driven up beyond the temperature within the Earth's mantle so they remain solid.

Which factor keeps the mantle rocks from melting even though the earth's interior temperatures are very hot?
The high pressure exerted by the overlying rock layers on the mantle rocks prevents them from melting, even though the temperatures in the Earth's interior are very hot. This pressure increases the melting point of the rocks, making it more difficult for them to melt.
How does heat move through Earth's interior?
Heat moves through Earth's interior mainly through conduction, as the hot molten rock in the mantle conducts heat to the cooler upper layers. Convection also plays a role, as the hot material rises and the cooler material sinks, creating a circulation of heat. Heat can also be transferred through radiation, though this is less common in Earth's interior.
Explain the sequence of events that cause the movement of the plates on the earths surface use these terms core heat mantle flow rise sideways drag cools?
First the heat below the mantle makes even the solid part of the mantle flow very slowly as though it were very thick liquid. the hot rising part of the mantle cools as it nears the crust. as the cooling mantle moves sideways it drags along the plate floating on top of it. the arrows show the cooled mantle sinking back down. later on the mantle will may be get warm and rise again.
What are convection currents in a mantle?
The asthenosphere is the layer of the Earth directly below the brittle lithosphere, made of solid rock with a small percentage of melt, which is under tremendous pressure and temperature conditions. It performs and moves in a ductile fashion (highly viscous) even though it is considered rock, and does not break while under stress, but can move due to convection currents of heat arising from Earth's interior.
What is the hardest layer in the Earth?
The inner core is the hardest layer in the Earth, consisting mainly of solid iron and nickel. Its immense pressure keeps it in a solid state even though it reaches temperatures of up to 9,000 degrees Fahrenheit.
Which factor keeps the mantle rocks from melting even though the earth's interior temperatures are very hot?
The high pressure exerted by the overlying rock layers on the mantle rocks prevents them from melting, even though the temperatures in the Earth's interior are very hot. This pressure increases the melting point of the rocks, making it more difficult for them to melt.
What planet temperature is closest to the earths?
Mercury has an average surface temperature (67°) closest to the Earths average surface temperature (14°C). The temperature on Mercury varies a lot though - you could argue that Mars is closer in temperature.
Why is earths inner core solid even though its temperature is hotter than that which would melt iron?
it is like 62,000,00 degrees down there
Is the mantle made of hot and solid rock that can flow?
Yes, the mantle is made of solid rock that can flow due to its high temperature and pressure. This slow flowing movement of the mantle is known as mantle convection and is responsible for driving plate tectonics.
What kind of heat transfer causes earths major heat patterns?
Our planet is warmed by conduction (heat from the mantle below), convection (tropical heat is transferred to the poles by wind and currents) and radiation (primarily the warmth of the sun, though there's also radioactive decay occurring in our planet's core).
What is the inferior mantle?
The inferior mantle, also known as the lower mantle, is the portion of the Earth's mantle that extends from about 660 kilometers (410 miles) to approximately 2,900 kilometers (1,800 miles) deep. It is characterized by high pressure and temperature, leading to the solid state of silicate minerals, though they can flow slowly over geological timescales. This layer plays a crucial role in mantle convection, which drives plate tectonics and influences volcanic activity.
What is is the temperature of the earth's mantle?
Remember that the earth's mantle extends from a few tens of miles below the crust across several thousand miles to near the core. The mantle comprises about 85% of the volume of the earth. The core, you'll recall, is only a bit over 4,000 miles in diameter, and the diameter of the earth is a bit short of 13,000 miles. There's a lot of mantle, isn't there? The mantle is divided into two basic parts, the outer mantle and the mantle (inner mantle).The temperature around the outer mantle is about 300 to 500 °Celsius. At the outer core where it bounds the mantle, the temperature is a bit short of 4500 °Celsius. That's a big temperature gradient.You'll find links below to relevant articles, and you'll also find that the data presented varies a bit, as it should. No one has actually been very far "into" the earth, and, though we are a clever lot, we only have a limited way to "look into" the earth and see what's going on. Couple that with what we see looking around out here and you'll get some variation in what is thought to be inside. between 100 to1600 Celsius
Which layer of the earth does the convection necessary for plate motion occur?
upper mantle.
How does heat move through Earth's interior?

What are effects of gravity?
Gravity causes older people to shrink. Answer Had to chuckle at the first answer though it is not true. Gravity is that force , said to originate from the center of the earth, which affects everything within its influence by attracting it to the earths center. Luckily we have a hard mantle beneath our feet that prevents this from happening.

What does not pass through earths interior at all?
An albatross can not pass though the Earth's interior at all, neither can a remote star or a jellyfish. This may seem like a nonsense answer, however I assure you it is a true and accurate answer to the question. The problem is that when a question is non specific and is asked in the negative, almost everything is a correct answer. Please try and take the time to be specific with your questions.
