Does the temperature increase during melting?
Explain why

Melting is the process where the atoms of a rigid solid Crystal lattice held by strong bonds, are broken down which increases the degree of locomotion of these atoms which characterises the liquid state.

The energy that breaks these bonds is heat energy ( latent heat of fusion ), hence temperature increases

explanation:

plate tectonics and volcanic euptions

over time, plate tectonic processes cause continents to move to different positions on the globe.

for example, britain was near to the equator 300 million years ago, and therefore was hotter than it is today. for further details look at our climate through time poster or online map.

the movement of the plates also causes volcanoes and mountains to form and these too can contribute to a change in climate.

mountain ranges formed by plate tectonics. large mountain chains can influence the circulation of air around the globe, and consequently influence the climate.   warm air might be deflected somewhere cooler by the mountains.
