What controls the style of a volcanic eruption?

Geography

storchak [24]3 years ago

Foremost of these are magma viscosity, gas loss and external properties such as conduit geometry. Ultimately, these parameters control the speed at which magmas ascend, decompress and outgas en route to the surface, and thus determine eruptive style and evolution.

In general, which two factors determine the overall temperature of Earth’s atmosphere?
kirza4 [7]

Answer:

The two factors are-

(1) amount of incoming solar radiations

(2) amount of outgoing radiation

Explanation:

The temperature of the earth's atmosphere is directly related to the amount of solar radiation present in the atmosphere. These radiations are the harmful ultraviolet radiation emitted from the sun.

According to the earth's heat budget, out of the total amount of solar radiation, 30% of it is directly reflected back into space, and the remaining 70% is absorbed.  

Again from this 70% of radiations, about 23% is absorbed in the atmosphere and the remaining 47% is absorbed by the earth's surface.

When the amount of radiation absorbed is more than the radiation reflected than in that case, the temperature of the earth's atmosphere increases. And when the amount of radiation reflected is more than the radiation absorbed, then, in that case, the temperature of the earth's surface decreases.

Thus, the amount of incoming and outgoing radiations must be maintained for the existence of a moderate type of earth's atmospheric temperature.

a woman is three times as old as her daughter. six years ago, sum of their ages was 36. find the age of the daughter​
sattari [20]
The daughter is 16 years old. This is because to find the sum of their ages now you multiply 6 ( the amount of years that have passed) by 2 (1 year for each woman) and the answer is 12. Then you add 36+ 12 which is 48. Since the mom is three times older than her daughter you divide 48 by 3 which equals 16. I hope this helps!
