How does temperature affect a catalysis

A catalyst provides an alternative pathway for the reaction, that has a lower activation energy. ... Increasing the temperature will mean there are more particles with high energy, greater than the activation energy, so a higher chance of a successful reaction.

the mantle

explanation:

earth is divided into three layers: the crust or the outermost layer on which we live; the underlying, middle layer - the mantle - and the core (the innermost layer of earth).
