Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
What happens to density, pressure, and heat as you go from the crust to the core of the Earth?
A
They all increase as you move inward
B
They all decrease as you move inward
C
Density and pressure increase while heat decreases inward
D
Pressure and heat increase while density decreases as you move inward
Explanation: 

Detailed explanation-1: -Temperature and pressure progressively increase with increased proximity to Earth’s core. Recent studies indicate the core’s temperature may be close to 11, 000 degrees Fahrenheit; that’s nearly 2, 000 degrees warmer than previously thought and hotter than the surface of the Sun, according to a 2013 Forbes article.

Detailed explanation-2: -Temperature increases due to the gas and pressure present inside the surface of the earth. The temperature increases because we go near to the core of the earth which is metallic and hotter.

Detailed explanation-3: -Earth density by core, mantle, and crust But if you compare Earth density by its layers, density steadily increases as you go inwards from the crust to core. INNER CORE: Earth’s inner core has the highest density at 12.9 g/cm3. OUTER CORE: Next, the outer core has a density of about 11.0 g/cm3.
