The model above shows layers of sediment on an ocean floor. Which of the following can explain how these layers can become rock over many years?
sand in the sediment melts and turns into rock
weight of the water compacts the sediment into rock
changing water temperatures turn sand in the sediment into rock
pollution caused by humans turns sediment into rock

Sedimentary rock is made of layers
Sedimentary rock is made of cemented bits of rock
Sedimentary rock is often limestone
Sedimentary rock is often common in Texas.
Which statement correctly describes the Sun's apparent movement across the sky?
