If 8 of the picks are orange, 6 of the picks are green.
Answer:
D)
Explanation:
Divergent plate boundaries occur when two tectonic plates are moving apart, such as the Eurasian Plate and the North American Plate. As the plate move apart energy, can be released as an earthquake. In the place of the lithosphere that is being dragged apart, magma can seep through as a volcanic eruption. In some cases the new volcanoes can for mountains along the middle of the Atlantic Ocean, dividing the tectonic plates. It can also cause a rift valley.
Answer:
slab pull
Explanation:
Slab pull convection model suggest that cold oceanic lithosphere sinkd to great depths (the asthenosphere) and that as they sink, they pull trialing plates along.
Answer:
Extreme weather conditions
Polar ice melting
Acidification of oceans
Explanation:
Global warming is a phenomenon that refers to increase in temperature of the earth surface as a result of the concentration in the amount of greenhouse gases in the atmosphere. Greenhouse gases like carbon dioxide, methane, water vapour in their normal amount helps to trap some part of solar radiation which is useful for all life on earth. If the proportion of these gases increase beyond normal, more radiation will be trapped and a surge in surface temperature results. This increase in temperature leads to:
- Extreme weather conditions: Hurricanes, tornadoes becomes more prevalent as there is more heat in the atmosphere.
- Polar ice begins to melt as a result of increase in the temperature of the earth surface.
- Due to surge in the amount of carbon dioxide on the earth, the ocean dissolves the gases and this leads to the formation of weak carbonic acid.
