How are valleys and trenches alike and how do they differ?
Unlike deep sea trenches which are found in areas where one tectonic plate slides beneath another undersea canyons are found along the slopes of most continental margins the submarine canyons for example tend to have steeper side slopes much higher gradients and considerably narrower floors. thats how they different
What are continental trenches?
coninental trenches are trenches that go across countries...i think
What was the reserve trenches like?
Reserve trenches
When was In the Trenches created?
In the Trenches was created on 2007-01-30.
What is a reserve trench?
Reserve trenches were used as supplies for the trenches out the front. In world war one, they had come up with a technique of hiding in trenches before they fight. To do this properly, they had made them zig-zags. The trenches on the front line were where the soldiers would fight from. Reserve trenches were used in case these people had anything happen to them and they needed to use more trenches and more men. Throughout the war, the conditions of the front line trenches became worse as the communication and reserve trenches improved. I hope that helped :)
How do active margins differ from passive margins?
Passive continental margins are not areas of convergence. There is little volcanic and earthquake activity on passive margins. Active margins are areas of convergence where one plate is descending beneath another. They are associated with volcanic and earthquake activity.
What causes submarine canyons?
passive margins
Why do only active margins have trenchs?
Trenches are caused by subduction.
What true of passive continental margins?
they have a continetal rise (
What is true about passive continental margins?
They have a continental rise
What is the difference between a passive continental margin an an active continental margin?
Passive continental margins are not areas of convergence. There is little volcanic and earthquake activity on passive margins. Active margins are areas of convergence where one plate is descending beneath another. They are associated with volcanic and earthquake activity.
Which of the following is true of passive continental margins?
they have a continental rise
Where are broad sediment covered continental shelves found in active pr passive margins?
passive margin
What are Continental margins near the edges of converging plates?
In the main along the mid oceanic ridges and along oceanic trenches.
What does a passive continental margin have which other margins lack?
A continental rise.
During which period was Laurentia completely surrounded by passive margins?
The Cambrian
What is usually found at an active margin but NOT at a passive margin?
Active and passive margins describe the various characteristics of continental margins that are a result of plate tectonics. An active margin usually has numerous volcanoes and mountains, while a passive margin typically do not have these formations.
