Why is the distance from the UK and America increasing?
New crust is forming at the Mid-Atlantic Ridge, causing the Atlantic ocean to grow wider at a rate of about 3 centimeters per year.
The Atlantic Ocean has been widening at the rate of about?
The same rate as your fingernails are getting longer each year!
Why are the magnetic strips in the pacific ocean wider than the ones in the Atlantic ocean?
The Pacific seafloor formed at a faster spreading rate than the Atlantic seafloor.
How the sea floor changes over time has given scientists information about the -?
formation rate of the ocean crust
At what rate does the water in the north atlantic ocean sink?
5 billion gallons per sec.
Determining how the sea floor changes over time has given scientists information about the?
formation rate of the ocean crust
Determining how the sea floor changes over time has given scientists information about the -?
formation rate of the ocean crust
Does the Earth's crust move through the oceans?
In a sense, yes. The oceans lay on top of the crust. As the crust moves on top of the mantle at a speed roughly equivalent to the rate of fingernail growth, the ocean gets out of the way.
What is happening to the width of the Atlantic ocean?
Scientific studies have shown that the width of the Atlantic Ocean is expanding. Researchers have stated that this has to do with the effects of global warming and explains why the Pacific Ocean is decreasing in size. ++== YES - the Atlantic Ocean is widening, at a mean rate of 25mm/yr. The Pacific Ocean is closing. + NO _ Research has NOT shown it has anything to do with climate change! It has nothing whatsoever to do with climate. + The changes are due to Continental Drift,. = The Atlantic floor is widening from the Mid-Atlantic Ridge constructive-plate margin with only limited subduction to absorb the growth in oceanic plate. The Pacific is closing by subduction around most of its coasts, more rapidly than its own spreading-ridges can compensate. + The Continental Drifts associated with these are of the American continent swinging North-Westwards, and the European Plates moving NE.
Which of the mid ocean ridges has the fastest spreading rate?
The Pacific region spreads 80-120 mm/yr, while the north Atlantic Ocean is just ~ 25 mm/yr.
Is the Atlantic Ocean a tropical ocean?
The short answer to your question is that it depends where you are. Here is the long answer The Atlantic Ocean is one of the largest oceans and, it extends from North America to South America. In the extreme northern and southern reaches it is referred to as a temperate ocean, this is due to the cooler sea temperatures and seasonality this area is one of the most productive areas of any ocean. Most large animals, such as whales, seals and the like are found in the temperate regions due to the massive proliferation of algal growth in the summer months, which fuels a massive food chain. However between the tropic of cancer and capricorn the Atlantic is considered tropical with much less if any seasonal change and higher temperatures, it is in this region that you will find coral reefs. You might be interested to know that the Atlantic is the youngest of the great oceans, and is expanding at the rate of ~3cm/ year.
At what rate do continents move apart?
sea floor spreadingThe continents of South America and Africa started to spread apart when the mid-Atlantic ocean ridge started creating new oceanic crust which pushed the continents apart.
