Yes, it is a solid with the uncommon characteristic of plasticity. It is a solid with the ability to flow like a liquid, but the mantle moves slowly. If you could kick it, you would stub your toe.

Why do scientists think earths core is made of iron?
Apex anwser Iron is a heavy element and would sink into the planet.
Where is the early atmosphere thought to have come from?
It comes from the process of planetary differentiation. light elements such as nitrogen rise up to form the atmosphere,whereas heavy elements such as iron sink to the mantle.
Why do convection currents happen in the mantle?
The convection currents are a result of heat from the interior of the Earth. The rock of the upper mantle known as the asthenosphere is plastic-like but not molten. It acts like a conveyor belt, moving heat from Earth's interior upward, and cooled material downward in a big loop. New crust is created where mantle material reaches the surface at places called mid-ocean ridges. Older, colder oceanic crust is subducted and drawn into the mantle, completing the loop.
Is most of the earth's heat is stored in the mantle?
No. The Earth's core and mantle would have cooled down by now (4500 million years of cooling) if the heat in the centre were just residual heat from the Earth's formation. When the Earth was forming and entirely molten, all the heavy elements will have sunk into the core of the planet, separating themselves out into layers of increasing density (this layering would have been disturbed somewhat by convection movements). This would mean that the very heavy radioactive elements would have moved to the core and it is the decay processes of these that is keeping the interior of the earth hot and has been driving plate tectonics and volcanic activity. In essence the planet is a slow fission reactor/bomb. You may well ask - if all the heavy elements sank, why can we find any at the surface now? - and the answer to that is that a second wave of heavy elements was delivered to the planet after the surface had solidified/cooled, in the late heavy bombardment (which is probably when Earth's) water was delivered too.
Why do geologist think earths core contains mostly iron?
Other orbiting bodies contain more iron then earths crust does
What is the layer of heavy rocks beneath the Earth's crust?
The upper mantle.
What is the layer of heavy rocks beneath the earth's crust called?
The upper mantle.
What is the size of the earth's upper mantle?
elephants anad feathers which make it light and heavy
How heavy is the planet of Neptune?
1.0243×1026 kg 17.147 Earths
What contribute to the lack of the evidence of the period of heavy bombardment on Earth?
Earths volcanoes;)
What contributes the lack of evidence of the period of heavy bombardment on earth?
Earths valcanoes
Why is there so little evidence of the period if heavy bombardment on earth?
Earths volcanoes;)
What human action does not alter the earths landscape?
Wearing heavy clothes in cold climates.
How heavy will you be on Jupiter?
you will probablly be has light as a two year oldincorrect. Jupiter's gravity is far more heavy than earths, you'd way about 2.64 times more on Jupiter.
What area features weak winds and heavy precipitation?
Any place that features dry and wet seasons undergoes weak wind shifts and heavy precipitation. Several areas of the world like rainforests experience wet seasons.
Can earthquakes be caused by heavy precipitation?
i dont think so because earthquakes are created when the earth shifts and plates break and move away causing a earthquake
