its effects would be worldwide. Such a giant eruption would have regional effects such as falling ash and short-term (years to decades) changes to global climate. Those parts of the surrounding states of Montana, Idaho, and Wyoming that are closest to Yellowstone would be affected by pyroclastic flows, while other places in the United States would be impacted by falling ash (the amount of ash would decrease with distance from the eruption site). Such eruptions usually form calderas, broad volcanic depressions created as the ground surface collapses as a result of withdrawal of partially molten rock (magma) below. Fortunately, the chances of this sort of eruption at Yellowstone are exceedingly small in the next few thousands of years.

I’m pretty sure the mature river is the bottom one, the old river is the middle and the young is the top. Hope I’m helpful..
Answer: From Earth POV, the new moon will appear to be completely dark, while the full moon, it will appear completely lit up
Explanation: In the new moon phase, the moon is in between sun and earth, the new moon phase is lit on the side of the moon thats facing the sun, while dark on the side facing the earth, in the full moon phase, the side of the moon facing the sun is also facing earth, making it visible completely.
Answer:
They are found near the equator
The temperature does not vary much
The animals often depend on camouflage for survival.
Explanation:
The bulk of the rainforest of the world straddles between 10 degrees north and south of the equator.
When you compare the temperature changes during a day in the tropics, it does not change too much. In some other climate, diurnal temperature changes is very wide e.g deserts.
Most organisms in the tropics relies on camouflaging as a means of survival. The biodiversity in the tropics is very high and a number of organisms coexists. In order for weaker and smaller organisms mostly the prey to survive, they have to camouflage and blend with the environment. Also, some predators also camouflage to deceive their prey.
Answer:
Option (3)
Explanation:
During the winter solstice in the northern hemisphere, the orientation of the earth axis is that it is tilted in the direction opposite to the sun. This means that during this time, the north pole is at the farthest distance from the sun which represents the darkest day of the year. It can occur on any of this dates, such as 20th, 21st, 22nd or 23rd of December every year.
The subpolar point is defined as the location on earth where the sun is directly overhead. This means that the light emitted from the sun strikes on earth exactly at 90°.
Thus, during this winter solstice, the sun is directly overhead in the tropic of capricorn.
Hence, the correct answer is option (3).
