Mantle: Silicate rock, probably hotter than the Earth's mantle at corresponding depths.
Mars's 3 layers are the crust, mantle, and core. Mars's crust is red and dust. Mars's mantle is made up of helium and rock substances. Mars's core is very hot. It is made up of iron.
There is no crust
: Why do astronomers conclude that the crust on Mars must be thicker then Earth's crust?

No, because mars' crust has a gas that makes its crust grow mehdeas and therefore earth has a much stronger crust.

Crust and Surface: Mars' surface is composed mostly of iron-rich basaltic rock (an igneous rock). Mars has a thin crust, similar to Earth's.Mantle: Silicate rock, probably hotter than the Earth's mantle at corresponding depths.Core: The core is made of iron and sulphides and has a radius of 800-1,500 miles (1,300-2,400 km).

Mars is smaller than Earth and consequently cooled quicker. Mars no longer has a molten core like Earth, so it would be fair to say it has a thicker crust.
The crust is thinner in the north.
