What are two bad things about plate tectonics?
Two bad things that can happen as a result of plate tectonics are: volcanoes and earthquakes.
What is the implication of being near a plate boundary?
If we choose to live near convergent plate boundaries, we can build buildings that can resist earthquakes, and we can evacuate areas around volcanoes when they threaten to erupt. Yes, convergent boundaries are dangerous places to live, but with preparation and watchfulness, the danger can be lessened somewhat.
What two features are commonly found at divergent boundaries?
Most divergent plate boundaries are underwater and form submarine mountain ranges called oceanic spreading ridges. While the process of forming these mountain ranges is volcanic, volcanoes and earthquakes along oceanic spreading ridges are not as violent as they are at convergent plate boundaries.
Which of the following is an example of a divergent plate boundary?
An example of a divergent boundary is the mid Atlantic Ridge (there are mid ocean ridges in the Indian, and Pacific Oceans as well). The Mid Atlantic Ridge creates volcanos where the hot magma erupts from the underlining mantle.
Are divergent boundaries An example of a subduction zone?
Divergent boundaries are areas where plates move away from each other, forming either mid-oceanic ridges or rift valleys. These are also known as constructive boundaries. This causes the oceanic plate to buckle and usually results in a new mid-ocean ridge forming and turning the obduction into subduction.
