What is the difference between fjord and a sound

In some places the trenches and valleys they left became lakes, including lakes Te Anau and Manapouri. In Milford Sound they created a fiord: a sheer, narrow valley opening out to the sea, with high cliffs on either side. You can see the passage of the glaciers over time in the shape and height of the cliffs that rise out of the sea.

As years went by and the glaciers melted the thickness of the ice changed, resulting in the ridged walls and U-shaped glacial valleys you can see today.

As the glaciers started to retreat back towards the mountains, they left behind huge deposits of the rock and debris they had brought with them down the mountains. This sill forms a barrier which stops big ocean swells from coming in, keeping the waters inside relatively calm. The most common rock types in Milford Sound are gneiss in many areas containing large garnet crystals and diorite, with some granite.

There is also pounamu or greenstone around Milford Sound, also known as nephrite or jade. This was formed by the recrystallisation of minerals within rocks deep below the surface of the earth, due to the enormous heat and pressure caused by tectonic shifts hundreds of millions of years ago. It's either in or near Acadia National Park, I can't remember which. In the ocean running under a bridge at the base of some large rocks, we saw a powerful and fascinating swirl of water which we were told was the only true fjord on the East Coast.

My friends have recently returned for this summer, and I just received an email saying that, although it looks the same to them, the fjord had been "downgraded" to a fjard. What's the difference between the two, and why would the fjard be considered a "downgrade" in status? Somes Sound is a large and deep body of water located in the lower mid-section of Mount Desert Island, Maine, whose cavity was formed from past glacier activity.

The tide was out so the pictures we took weren't as dramatic as what we actually saw last year. Hopefully they're good enough to give you an idea. Click on them for larger view. I think Wikipedia article on Fjard has a very good explanation:. Although fjards and fjords are similar in that they are a glacially-formed topography, they still differ in some key ways. Fjords are characterized by steep high relief cliffs carved by glacial activity and often have split or branching channels.

Fjards are a glacial depression or valley that has much lower relief than a fjord. Fjards fill with eroded local materials which assists "filling" along with rising sea level since the last ice age contributing as well. Other low relief landforms that are only associated with fjards such as mud flats, salt marshes, and flood plains further characterize the difference between fjords and fjards. The landforms feature prominently in different places of the world and are unique to their environments.

Bays, bights, fjords, and sounds support a variety of commercial and recreational activities. A fjord is commonly found in regions where the present or past glaciations are below current sea level.

A fjord appears as a narrow steep-sided valley filled with seawater. It is formed by a glacier which washes away the bedrock of an area as it tumbles down. The fjord is primarily formed through glacial activity in the context of other geographical processes such as fluvial erosion and tectonism.

Fjords are surrounded by outstanding mountain scenery and are popular with sightseers as a result. Its mouth, where it opens to the sea, is often shallow. The deepest part of a fjord is found inland since glacial forces were strongest at that point. Fjords also have other features which include skerries and coral reefs. The fjord located in the western part of the country forms the Fjord of Norway where a series of them create a stunning landscape.

These fjords are home to abundant wildlife and small communities and settlements populate their sides. The Scoresby Sound takes the crown of the largest fjord system in the world.

Sound, as a slang adjective, can mean "excellent. Is Milford Sound a lake? Glaciers in Milford Sound In some places the trenches and valleys they left became lakes, including lakes Te Anau and Manapouri.

There is a terminal moraine deposit or 'sill' at the mouth of Milford Sound, leaving the floor of the fiord just 27m deep at this point compared with over m deep on either side.

What does a river sound like? A stream burbles as it travels along its bed, bubbling over rocks and branches. You could also say that a brook or stream or river babbles or ripples or even trickles. The word burble was first used in the 's, and it probably comes from an imitation of the sound a rippling, bubbling brook makes. Why is Puget Sound called a sound? This name later came to be used for the waters north of Tacoma Narrows as well.

Why is a fjord important? These regions serve as important transition areas between the land and sea environments and provide habitat not only for humans e. Scientists love to study fjords as model systems. Are there sharks in fjords? However, fjords can be found in some areas south of the equator that are near coastal mountain ranges, most notably New Zealand and Chile.
