Today the Atlantic Ocean is about 5,700 km wide at the latitude of Boston. At one time, however, there was no Atlantic Ocean because the east coast of the United States and the northwest coast of Africa were joined in a huge supercontinent. The Atlantic Ocean started to form "only" 185 million years ago, as modern North America split from Africa and the two continents slowly drifted apart in a process called seafloor spreading. Assuming that the rate of seafloor spreading has been constant, at what rate has North America been moving away from Africa? Give your answer in millimeters and kilometers.

Answers

Answer 1

Answer:

5700 / 18,500,00,00 = 30.8 mm/yr;  or 30.8 km/Myr

Explanation:

North America and the African plates moved away from each other due to the spreading of the Atlantic ocean and the opening of the mid-Atlantic ridge. That develops a diversion motion and separated the plateau in the west and eastern direction. This also leads to the splitting of the south American plate away from the African continent.

Answer:

Biomes on Earth have exhibited changes throughout history that have been caused by a variety of factors. Over the past 50 years, the amount of tropical rainforest acreage found throughout the world has decreased from 14.8 billion acres to 8.6 billion acres due to deforestation.

What factor is likely most responsible for the changes observed in the world’s rainforests?

b. human activity

Especially in tropical forests, there are changes made by human activities through incessant deforestation (legal or illegal), deforestation and land use for agriculture or housing.

Over the past 50 years, tropical rainforest acreage has decreased massively as a result of b. human activity

Tropical rainforests have seen a massive decrease as a result of humans cutting down trees because:

They use the trees in the logging business They use the land for farming and settlement

As the human population grows, the rainforest continues to shrink as people continually claim land from the forests for settlement and farming as well as business activities. This has led to the massive drop in rainforest acreage.

In conclusion, human activity is to blame for the loss of rainforests.
