Which planet has a large solid core?
Scientists suspect that of the well known planets that Jupiter has a solid core that is large in size. It has been discovered that Jupiter contains a core that includes rock and hydrogen metals, but scientists are unsure if deep within the planet contains a true solid core. Of all the nine planets, Jupiter's core contains the most "solid" case for a true solid core.
Asked in Geology
What evidence led scientists to the conclusion that earths inner core is solid rock?
What are some of the differences and similarities between the mantle crust and the core?
Similarities- The Mantle and the core are both solid and molten. The upper mantle is made of solid rock and the inner core is solid because of extreme pressure. The lower mantle and the outer core are both molten rock. Differences- Temperatures -mantle= upper mantle is 1000o C and the lower mantle is 2500 -core= outer core is 4000o C and the inner core is 5000-5700
Asked in Geophysics
What extends from earth core to earth spheres?
The structure of the earth is several nested roughly spherical objects: solid core - nickel iron metal alloy (at center) liquid core - molten nickel iron alloy mantle - solid but slowly convecting basalt rock crust - solid granitic and sedimentary rock (at surface) also called lithosphere, meaning rock sphere
Asked in Geology, Earth Sciences
What is the composition of the crust mantle and core?
the continental crust is mostly granitic type rock, the oceanic crust is mostly basaltic rock, both include a variety of sedimentary and metamorphic rocks; it is in the solid state of matter the mantle is basaltic rock; it is in the solid state of matter but is plastic and flows slowly the core is a metal alloy composed mostly of nickel and iron; the outer core is in the liquid state of matter, the inner core is in the solid state of matter
