I do not believe that a strong nation should be able to boss around weaker nations. This is just wrong in that a nation should be free to decide what it wants to do. A strong nation can assist them in developing. How ever they should not rule them. At that point that weaker nation will be stripped by of their sovereignty. This is not that times of Empires.
Answer:
During the break-up of Pangaea, South America split off from Africa, North America split off from Eurasia and Australia split off from Antarctica and drifted north.
Explanation:
- 290 million years ago, the Pangaea pracontinent was formed surrounded by a huge ocean.
- About 250 million years ago, collisions of tectonic plates caused earthquakes on the ocean and on the ocean floor.
- The continent cracked, and then the Tethys Sea slowly split Pangaea into two continents - Laurazia and Gondwana.
- Then, 163 million years ago, Gondwana split into Africa, Antarctica, Australia and South America.
- These continents eventually separated from each other, creating the southern Atlantic Ocean and the Indian Ocean. Eventually, 60 million years ago, the northern part of the Atlantic Ocean slowly separated, eventually creating Europe and North America.
Urbanization brings noise pollution due to a larger population. This can be seen as one challenge. Another challenge is pollution such as plastic, gases, noise, etc due to the larger population. Also a big challenge is danger. You do not know the people as much in a larger town, therefore the danger to you is a lot more prominent.
Sacramento River geologic unit details are described below.
Explanation:
1.The Sacramento River is the main river of Northern California in the United States, and is the largest river in California. Rising in the Klamath Mountains, the river flows south for 400 miles (640 km) before reaching the Sacramento–San Joaquin River Delta and San Francisco Bay.
2.Sacramento River, river is rising in the Klamath Mountains, near Mount Shasta (in Siskiyou county), northern California, U.S. The river flows 382 miles (615 km) south-southwest between the Cascade and Sierra Nevada ranges, through the northern section (Sacramento Valley) of the Central Valley.
3.This river forms a common delta with the San Joaquin River before entering Suisun Bay, the northern arm of San Francisco Bay. Its principal tributaries are the Pit, McCloud, Feather, and American rivers. Total drainage area is about 27,100 square miles (70,200 square km); average annual runoff is 22 million acre-feet (27 billion cubic metres).
4. Shasta, Keswick, and Oroville dams are key features of the Central Valley and Feather River irrigation and power projects, which serve southern portions of the state. California’s largest river, the Sacramento is navigable for 256 miles (412 km) and accommodates oceangoing vessels as far as the city of Sacramento.The name Sacramento was originally given to the Feather River by Gabriel Moraga in 1808; it was later applied to the main channel (originally called Rio de San Francisco). Scene of the Gold Rush of 1849, the river flows through one of the world’s richest agricultural regions. The river harbours hundreds of species of fish, and the Sacramento River National Wildlife Refuge, in several units, protects several ecosystems.
