, the world was made up of a single continent through most of geologic
time. That continent eventually separated and drifted apart, forming
into the seven continents we have today. The first comprehensive theory
of continental drift was suggested by the German meteorologist Alfred Wegener
in 1912. The hypothesis asserts that the continents consist of lighter
rocks that rest on heavier crustal material—similar to the manner in
which icebergs float on water. Wegener contended that the relative
positions of the continents are not rigidly fixed but are slowly
moving—at a rate of about one yard per century.
It allows the grass and plants time to replace themselves when the animals migrate.
Answer:
The Pampas region has a big economic impact as it is the agricultural heart of Latin America.
Explanation:
The Pampas is a region that is mostly comprised of lowlands. Naturally, it is a biome where grasses dominate. The soil is highly fertile and the region as it is is relatively large. Humans have easily seen the potential of the Pampas and spend no time converting it in an agricultural landscape.
Latin America is a region that heavily relies on agriculture, both farming and raising cattle. Large, relatively flat land with fertile soil is excellent for farming, so the Pampas has been heavily exploited for the large-scale production of agricultural goods. Also, raising cattle is among the highest in the world in Latin America and it is constantly growing as a sector, and grasslands are needed to sustain the cattle, so the Pampas again is the place to exploit for it. While this has a big and positive economic impact, the effects on the flora and fauna of the Pampas have been devastating, to say the least.
