The spatial layout of Indo-European is very large, traditionally occupying most of the area from Western Europe to India, nowadays being even more spread out around the world.
Explanation:
The term Indo-European can refer to and ethno-racial group of people, or to the linguistics of a group of people. Anyways, this is the most wide-spread group of people in the world. The Indo-Europeans have their roots in the Aryan people from Central Asia, which managed to spread out anywhere from Spain and Britain in the west, to India in the east. The easternmost this group of people managed to get was in northwestern China, represented by the Tocharians.
- With the spread of the Indo-Europeans, their culture was spreading with them as well, thus their language with it.
- Most of Europe, Anatolia, Iran, and big portion of South Asia became dominated by these people and their languages.
- The people constantly migrate though, so lot of changes have happened, so the Indo-Europeans lost some areas in the Old World, but on the other hand, they spread out on three new continents, and soon became dominant on them.
- At present, this group of people and languages spatial layout is in most of Europe, Iran, big portion of South Asia, Northern Asia, North and South America, Australia, and smaller enclaves here and there scattered around the world.

Acid Rain is the natural cause which causes volcanic eruptions and emissions from vegetation.
<u>Explanation:
</u>
The volcanic eruption is a natural phenomenon that is caused due to the liberation of the lava from the heap of the earth along with the gases. The volcanic eruption results in causing major damages to the vegetation lying above the erupted crater of the volcano.
This results in the immense release of gases such as “carbon dioxide, carbon monoxide, sulphur dioxide, hydrogen chloride, hydrogen fluoride, methane and ammonia” and these gases are major pollutants of the air. When these gases react with water vapour that are present in the atmosphere, they condense in the form of acid rain.
