Which statement explains the relationship between the density of a material and its movement in Earth’s interior? Cooler materials move from Earth’s mantle to the lithosphere. Cooler materials are highly dense, causing them to sink to the outer core. Warmer materials sink to the mantle because their density slowly decreases. Warmer materials have a high density, causing them to rise to Earth’s surface.

In a vacuum, light travels at 670,616,629 mph (1,079,252,849 km/h). To find the distance of a light-year, you multiply this speed by the number of hours in a year (8,766). The result: One light-year equals 5,878,625,370,000 miles (9.5 trillion km).
