Explanation:
the air we breathe : the oceans produces over half of the world's oxygen or absorbs 50 times more carbon dioxide than our atmosphere. climate regulation : covering. 70% of the earth surface, the ocean transports heat from the equator to the poles,
regulating or climate and weather patterns.
earth quakes are usually caused when rock underground suddenly breaks a long a fault. this sudden release of energy causes seismec waves that make the ground shake. when two blocks of rock or two plates or rubbing against each other, they stick a little.... when the rocks break earth quakes occurs.
volcanoes erupt when molten rock called magma rises to the surface. magma is formed when the earth's mantle melts. melting may happen where tectonic plates or pulling apart or where on plate is pushed down under another. magna is lighter than rock so rises towards the earth surface.
