Question

The
(a) outer core
has the highest density, being both metallic and solid
(b) continental crust (c) lower mantle
(d) inner core​

Answer 1

Explanation:

outer core, continental crust

lower mantle

inner core

Earth's inner core is the innermost geologic layer of the Earth. It is primarily a solid ball with a radius of about 1,220 kilometres (760 miles), which is about 20% of the Earth's radius or 70% of the Moon's radius.[1][2]

Earth's inner core is the innermost geologic layer of the Earth. It is primarily a solid ball with a radius of about 1,220 kilometres (760 miles), which is about 20% of the Earth's radius or 70% of the Moon's radius.[1][2]There are no samples of the Earth's core available for direct measurement, as there are for the Earth's mantle. Information about the Earth's core mostly comes from analysis of seismic waves and the Earth's magnetic field.[3] The inner core is believed to be composed of an iron–nickel alloy with some other elements. The temperature at the inner core's surface is estimated to be approximately 5700 K (5430 °C or 9806 °F), which is about the temperature at the surface of the Sun.[4]
