Final answer:
The mantle is the earth's layer which comprises the largest percentage in volume, accounting for about 84% of the Earth's volume. It lies beneath the crust and extends up to 2,900 kilometres beneath the surface.
Step-by-step explanation:
The layer of the Earth that comprises the largest percentage in volume is the mantle. The Earth is divided into 3 main layers: the crust, mantle, and core (which itself is composed of the outer and inner core). The mantle is the layer that lies beneath the crust and it accounts for about 84% of Earth's volume. This earth's layer also extends up to approximately 2,900 kilometres beneath the Earth's surface. Inside this layer, temperatures can reach up to 4,000°C making it a dynamic and vital component of our planet.
