Question

Which of the following best describes a tectonic plate?

Answer 1

B Fragments of the Earths Crust that float on the Earths Mantle

Answer 2

Answer:

B

Step-by-step explanation:  Plates at our planet's surface move because of the intense heat in the Earth's core that causes molten rock in the mantle layer to move. It moves in a pattern called a convection cell that forms when warm material rises, cools, and eventually sink down. As the cooled material sinks down, it is warmed and rises again.
