How do volcanoes change the earth's surface?

Answer 1

Well they can destroy earths surface or it can build more habitats by changing earths land form and make a hole new habitat it can do many things some good some bad it can destroy and it can help earths surface

Answer 2

Volcanoes are structural upwellings of the planet's fiery interior through cracks in the rock crust and they ARE a change to earth's surface. Lava frequently flows from volcanoes and has played a part in changing the earth's surface by filling in lowlands and increasing the exterior size of the volcano itself. Some volcanoes are so violent that magma can explode from their openings and alter the surrounding topography for miles around with its fallout.

You have read that lava erupts from valcanoes on land. However, not all lava flows on land. Recall that the land masses that make up North America and Europe began to separate 200 million years ago when a divergent plate boundary formed between them. What happened in the area between these land masses as it became larger?

Answer 3

Not all volcanoes give out the same kind of emissions. Usually the most common gas is water vapour, followed by carbon dioxide and sulphur dioxide. Other gases include hydrogen sulphide, hydrogen chloride and hydrogen fluoride. These gases can add to the greenhouse gases, contributing to global warming. They can also cause acid rain. Ash from volcanoes is often a danger to jet aircraft and large eruptions of ash can alter the climate, often cooling it.
