Convection causes tectonic plates to move.
A) True
B) False

Hope this helps.

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. So I think false

meteorologists would compare a new weather map with one 24 h old to see how fast a front is moving.

a tetrad is the foursome during meiosis made by two homologous chromosomes that have each already replicated into a pair of sister chromatids.
