Answer:

The volcano injected some 15 billion tons of sulfur dioxide into the stratosphere. There it reacted with water to form a layer of aerosol particles, which are primarily sulfuric acid droplets. Winds have take those aerosol particles all around the world. The stratosphere lacks rain clouds as a mechanism to wash out pollutants fast. This heavy influx of aerosol pollutants will remain in the stratosphere for years until natural chemical reactions and atmospheric circulation can filter them out.

shtirl [24]

Answer:

<u>People who </u><u>flee persecution and violence</u><u> in their own country are considered asylum seekers while the people who </u><u>decide</u><u> to move to another country in order to seek employment and better life opportunities are considered migrants.</u> Migrants can be legal, moving threw documentation. Migrants are usually people with a strong resources in order to prepare their journey and arrival in the country of the destination. They save money, they gather the information about the trip and the destination and about the potential employment there, like how mast Europians or Asians come to america. They speak to friends and family at the destination who will help them upon arrival. They may speak to travel agents, potential employers at destination or middlemen of different sorts. They may try to learn the language of the destination country. In short, migrants clearly make decisions and take up the actions in order to prepare for their migration. This does not necessarily mean their migration is voluntary. The reasons for leaving their country of origin may have to do with circumstances that are beyond their the control. Migrating is not a decision taken easily, it involves high costs. They may do this to help family

why is it important to know the source of energy in convection currents to understand plate tectonic theory​
Lera25 [3.4K]

Its important to know the source of energy in convection currents because it is what drives the movement of the plates, formation of plate boundaries, and hot spots.

Explanation:

The convection currents are currents that occur in the mantle layer. The prime reason as to why they appear is the difference of heat and pressure between the upper and lower mantle. The energy itself exist because of the core of the Earth, as it is very hot and it has extremely high pressure, so it heavily influences the mantle layer above it.

The importance of understanding the energy source of convection currents is seen in that through it we can understand why we have plate boundaries at some places and not in others, why are spreading zones occurring, and why hot spots occur in the middle of the plates, far away from the boundaries. By understanding these things, we can understand the plate tectonics theory, thus the motion of the plates on Earth's surface.
