Answer:
the rocket average speed is 12 kilometers per second
Explanation:
Given that
The distance is 1140 km
And, the time is 95 seconds
We need to determine the average speed in kilometers per second (km/s)
So as we know that
Speed = distance ÷ time
= 1,140 km ÷ 95 seconds
= 12 kilometers per second
hence, the rocket average speed is 12 kilometers per second
The most appropriate answer would be magma. Lava is a magma that reaches the Earth's surface, which is technically it is also a magma, and magma is located below the Earth's surface.
Lava at Earth's surface or magma below Earth's surface cools and harden to form mineral crystals.
their relative densities
Explanation:
The relative densities of the earth's materials can be inferred by the arrangement of the earth layers.
Compositionally, the earth is made up of three distinct layers; core, mantle and the crust.
- The crust is the thin outermost layer of the earth.
- The mantle straddles the zone between the core and crust.
- The core is the innermost layer of the earth.
During the formation of the earth, materials differentiated into different layers based on density.
The densest materials settled in the core and they are made up of iron and nickel metals.
The lightest materials of silicate affinity partitioned to the crust.
The mantle contained materials whose density straddles between the crust and core.
