Answer:
C. Airborne ash and rocks from a volcanic eruption remain suspended in the air for a long time before eventually settling to the ground in a new location far from the volcano.
Explanation:
Tephra deposits take many forms and shape, and their composition doesn't really matter either. The only thing that defines a tephra really is that it was ejected from the mouth of a volcano and fell on the ground where it remained intact (not merged with something else).
So, forms of tephra could be big boulders landing on the volcano's side or ashes that travel around the globe to land on the other side of the planet.
Chile uhmm... I’d love to help but this is kinda difficult
Answer:
B. Melting polar ice caps
Explanation:
The global climate change is one of the most popular themes in the past few decades. It is a natural process that has been constantly happening on Earth, with periods of cooling down, or periods of warming up. In more recent times, the humans also started to contribute slightly to this process with the emissions of the greenhouse gasses, which are making the atmosphere warmer.
With the temperatures gradually rising on global level, there are numerous changes occurring. One of the most noticeable changes is the melting of the polar ice caps. Little by little, the polar ice caps and the glaciers are melting, thus decreasing the area occupied by frozen surface on the planet.
While it is almost impossible for the entirety of the ice caps to melt down until there is a large land mass on the poles, or one of them, it is most certain that the ice caps will reduce significantly. If the trend continues it will probably be only the interior of Antarctica that will preserve an ice cap.
