<span>Thermohaline circulation is driven by differences by "Density." Thermohaline circulation is a single part of the large-scale ocean circulation. It is driven by global density differences that is being created by the freshwater fluxes and as well as the surface heat.</span>
Physical evidence like fossils
and measurements like radiometry or Carbon dating
The answer is A. and B.
Let's look into the options one by one:
A. pressure and heat built up in the magma chamber
This is true as the pressure and heat built up is what cause the magma to be pushed out of the chamber through the vent. The higher temperature it is,the more it expands and the more likely it is to erupt.
B. plate tectonics and subduction
This is also true as volcanicity is caused by plate tectonics such as subduction. When the plate bends, cracks are formed which coul then be filled by magma and cause fissure eruption, afterwards forming volcanoes.
C. ground swelling and foreshocks
These are the consequences of volcanic eruption but not the causes and therefore is not true.
D. foreshocks and aftershocks
These are as well the consequences of volcanic activity like above and is not true.
Therefore the answers are A. and B.
Hope it helps!
Answer:
Explanation:
The tilt of the earth's axis.
If you put a couple of toothpicks in an orange or an apple and make them so they are at a 45 degree angle and tilt the orange so it rotates on an axis made by the toothpicks, you will see how this works.
Turn off the lights and shine the orange with a flashlight. Now rotate it using the toothpicks as an axis. Go slowly. Notice how if you tilt the top toothpick towards the flashlight, it looks different than if make the top toothpick further away from the flashlight.
What you've done is exactly what the earth would do when its axis is closer to the sun and further away from the sun.
I hope this is clear enough.
