That humans will ever be able to travel deeper then the crust of earth why or whynot?
It is highly unlikely that humans will ever be able to travel deeper than the Earth's crust due to extreme temperatures, pressures, and geological obstacles present in the Earth's mantle and core. The technological challenges and risks involved in developing the necessary equipment to withstand such conditions are currently insurmountable.
Which layer of the earths layer is the coolest?
The coolest layer of the Earth is the lithosphere, which is the rigid outermost layer consisting of the crust and upper mantle. This layer's temperature decreases with depth, making it the coolest part of the Earth's structure.
What is the difference between the crust and the mantle?
The crust is referred to as the outer skin of the planet, where all life as we know it exists. There are two types of crust--continental, which is granitic in composition, and oceanic, which is basaltic in composition. The depth of the crust varies from about 0-40 miles, and is composed mainly of silicate rich rock.The mantle extends from the boundary with the crust, to a depth of around 1800 miles, making it Earth's most massive layer. The uppermost layer is a brittle solid and is attached to the crust. Directly underneath the crust and uppermost mantle lies the asthenosphere, where hot solid rock is in a plastic-like state, able to move long distances on geologic time scales. This plasticity decreases with depth as the lithostatic pressure increases toward the boundary with the core. Chemically, the mantle differs from the crust in that the rock is ultramafic (very high in iron and magnesium) compared to the more silica rich rock of the crust. Temperature also increases with depth (geothermal gradient), and therefore temperatures in the mantle are significantly higher than in the crust.
What are the properties of the mantle?
It is mostly solid rock, but less viscous at tectonic plate boundaries and mantle plumes. Mantle rocks there are soft and able to move plastically (over the course of millions of years) at great depth and pressure. The transfer of heat and material in the mantle helps determine the landscape of Earth
Why do mantle convection currents rise under mid ocean ridges?
They don't. The presence of magma at mid-ocean ridges is due to the effect of less pressure on the mantle below known as "decompressional melting". Mantle rock is extremely hot, yet it remains in solid state because it is under immense pressure. At mid-ocean ridges, where tectonic plates are pulling apart, the crust is thinner, meaning less pressure on the mantle rocks below, thus they are able to melt, become less dense and rise.
Why is the crust able to float and move on top of the mantle?
it is floating on it
How miners been able to dig into Earth's crust?
miners have been able to dig into the earths crust by big machines and other huge tools and they have only dig ed 2 miles into the earths crust
How is crust different from mantle?
The crust is the outermost layer of the Earth, which is thin and solid. It is divided into continental crust (underneath land) and oceanic crust (underneath oceans). In contrast, the mantle is the layer beneath the crust and is primarily composed of solid rock that flows slowly over long periods of time.
Why didn't the mantle itself shrink and the thickness of the crust increase?
The mantle is under high pressure and high temperature, which helps maintain its volume even as the crust thickens or thins. The mantle is a semi-fluid layer that can flow and adjust to changes in the crust without significant changes in its overall volume. As the crust thickens, the mantle can undergo convection to redistribute its mass and maintain equilibrium.

Is the rock in the crust able to move around more easily than the rock in the lower mantle since the rock in the crust moves around differently than rock in the lower mantle?
The rock in the lower mantle moves around easily than the crust. This is because rock in the lower mantle is hotter and closer to its melting point. Rocks in the crust are cooler thus harder to move around.
How are the asthenosphere and lithosphere involed with plate tectonics?
The lithosphere is the brittle surface layer composed of the crust and uppermost mantle. The asthenosphere is the ductile upper mantle on which the lithosphere is able to move.
How have scientists been able to able to study earth's mantle?
In some places, Earth`s crust thins enough to see mantle.
Is magnetic stripes on the ocean floor the places where oceanic crust sinks back to the mantle?
it is right in your book soo... you should be able to answer this

Which layer of earth are made mostly of rocks?
Hard rocks form the outer layer of the Earth (the lithosphere) which includes the crust and upper mantle. Rocks of the remaining mantle are in a plastic state, able to move, bend and deform without breaking.
