Answer:
new volcanoes
Explanation:
The mid-ocean ridges occur at places where there is a divergent plate boundary between two plates, and the boundary is located on the ocean floor. At this type of boundaries, the tectonic plates are moving away from each other, and there is constant volcanic activity between them.
The volcanic activity produces lot of magma, which quickly cools off in the water and piles up, creating underwater mountain ranges known as mid-ocean ridges. This constant piling of igneous rocks from the rising magma, produces new crust, or rather creates new ocean floor.
The old ocean floor is pushed aside, and there is a general principle that the crust at the mid-ocean ridge is the youngest, and the further away a place it is from it, the older the crust is.
Along all of the mid-ocean ridge there is constant volcanic activity, and that volcanic activity creates lot of new volcanoes on the ocean floor.
The state of Washington has a very good location which benefits its economy and development a lot. The state is located in the northwestern part of the United States. It comes out on the Pacific Ocean, and it has nice coastline which is suitable for ports. Also, it is bordering Canada, and is in very close proximity to the biggest Canadian ports on the Pacific Ocean.
This results in lot of trade going through this state, be it between USA and Canada, or between USA and Asia. Also, it is a state that not only has ports, but has one of the most important ports, through which one of the largest amounts of products and goods go through. They are then distributed throughout the country, or vice versa, they are brought from all over the country.
With South Americas Rain forest , it produces 20% of the earths oxygen. Also many drugs used to treat people have come the plants of Amazon. The worlds climate would be much different because ocean currents would be different . Europe would not have the warmth of the North Atantic drift current to keep it warm. It would be more like Siberia .It is located primarily in the southern hemisphere. It is bordered by the Atlantic Ocean to the east and the Pacific Ocean to the west. The geography of South America is dominated by the Andes Mountain Range and the Amazon River (second longest river in the world).Andes Mountains. The Andean Mountains, or Andes, stretch for nearly 7,000 km across the continent, from the top to the bottom. ...
