Under gentle continuous pressure, the mantle would slowly deform and flow over long periods of time. This gradual movement of the mantle is known as mantle convection, where warmer, less dense rock rises and cooler, denser rock sinks, driving the slow movements of tectonic plates on Earth's surface.
What else can I help you with?
How would the earth's mantle react under gentle continuous pressure?
it will steady as liquid form and hot
What three differences between the upper and lower mantle?
The upper mantle is composed mostly of solid rock, while the lower mantle is under higher pressure and temperature, causing it to behave more like a viscous fluid. The upper mantle is part of the Earth's lithosphere and is involved in plate tectonics, while the lower mantle is located in the asthenosphere and undergoes convection currents. The upper mantle is closer to the Earth's surface and extends to a depth of about 410 miles, while the lower mantle extends from about 410 miles to 1,800 miles beneath the surface.
How is pressure involved in melting mantle material at a mid-ocean ridge?
Pressure is involved because as the plates move apart, lower mantle material is hot, flexible, and solid. This rock is solid because of the great pressure of the layers above it. However. as the rock of the lower mantle rises, the pressure drops and the material melts.
What is the range of pressure within the stiffer mantle?
The pressure within the stiffer mantle ranges from about 14 GPa (gigapascals) at the upper boundary to over 136 GPa at the core-mantle boundary. This high pressure contributes to the solid-state behavior of the mantle material despite its high temperature.
What pressure allows diamonds to form in the mantle?
The high pressure in the Earth's mantle, estimated at around 725,000 pounds per square inch (50,000 atm), is what allows diamonds to form. This pressure is combined with high temperatures and specific carbon-containing fluids in the mantle, which lead to the crystallization of diamond.

How would the mantle react under gentle pressure?
Well, honey, the mantle would probably just shrug it off like a bad date. It's used to handling all sorts of pressure, so a little gentle nudge wouldn't faze it much. Think of it like a tough cookie that can handle whatever life throws its way.

Which layer is believed to behave most like a liquid?
If we're talking layers of the earth, that would be the upper mantle, below the crust.
How does the weight of the lithosphere affect the mantle?
The rock of the mantle is hot enough that it would melt at surface pressure. The weight of the lithosphere creates such great pressure on the mantle that it remains solid.
What is the pressure of the upper mantle?
somewhere between 1000 to 4000 degrees Celsius.
Does the mantle have the most pressure?
yes it does
What causes pressure to cause diamonds in the mantle?
The weight of the rocks in the crust and upper mantle results in the pressure that allows diamonds to form.

Why is the lower mantle denser the the upper mantle?
The lower mantle is under greater pressure than the upper mantle, compressing the rock into a denser form.
How is the temperature and pressure in the Earth's mantle related to the depth of the mantle?
The degree of temperature and exertion of pressure by the molten materials (magma) within the mantle is directly proportional to its depth. This means that, the deeper you go down the mantle the higher the degree of temperature and pressure exerted.
Why is the pressure in the center of the earth greater than the pressure in the mantle?
Because towards the center of the earth, there is more mass on top of it, so there is more pressure. All of the other layers, and the stuff on top of the earth is pushing down on it from all sides. For the mantle, its only the stuff on the top of the earth that is putting pressure on it.
