Answer:
1. As temperature and pressure increases, density increases
Explanation:
The earth is composed of three main layers: Crust, Mantle and Core. The density or mass per unit volume of the earth's layers increases as one moves from the surface towards the interior of the earth known as the core. Also, there is an increase in pressure and temperature as depth increases. There are three main sources of heat in the earth's core: (1) conserved heat from when the planet formed and coalesced, (2) heat due to friction caused by denser core material sinking to the center of the planet, and (3) heat from the decay of radioactive elements.
The earth's core is composed almost entirely of the metals, iron and nickel. The core has an inner solid layer and a molten outer core. Iron and nickel are both very dense metals, so the core of the earth is very dense and the density increases with depth with the inner core being the most dense layer of the earth.
The travel to the galciers is something one can never forget. The aura of the place along with the beauty that one gets to notice is so enriching to entice one to stay there forever. The glaciers are one of the many natural wonders our world has to offer. Formed because of the accumulation of the snow year after year, these glaciers are present in many sizes. Besides, the movement of the glaciers, such as the glacial erosion and deposition leads to the formation of many other attractive features, such as the corries, pyramidal peaks, truncated spurs, and hanging valleys. You must definitely visit these places to give your soul this exciting experience.
