What processes found at a divergent boundary help form the following rocks?
The process of upwelling magma is found a divergent boundaries. As this magma nears the surface it decompresses, and some of it flows onto the surface of the Earth as lava. Magma that solidifies beneath the surface of the Earth hardens into gabbro while lava on the surface of the Earth hardens into basalt. Both of these are igneous rocks. Metamorphic rocks are formed from the heat flowing from the igneous rocks. Sedimentary rocks are formed from the sediments collecting in the basins created from rifting (that is, the divergent boundaries). Metamorphic and sedimentary rocks are not considered to be formed at divergent boundaries.
What is the similarities between convergent divergent and transform boundaries?
they both form volcanoes and earthquakes
Which two major rivers formed the western and southern boundaries of the northwest territory?
The Ohio and Mississippi rivers outlined the boundaries of the Western and Southern boundaries of the Northwest Territory.
What caused the Andes mountains to form?
They were formed by deposition and by convergent boundaries
What are artificial boundaries?
An artificial boundary is a boundary that is man made instead of naturally formed by nature. These boundaries include fences and dams.
Do trenches occur at divergent boundaries?
that is false
Do Trenches occur at divergent plate boundaries.?
that is false
Are divergent plate boundaries associated with folded mountains and deep sea trenches?
No. Sea floor trenches are found at convergent boundaries. divergen boundaries form mid-ocean ridges.
Ocean ridges are formed by what boundaries?
Divergent boundaries form ocean ridges.
Types of landforms formed by divergent boundaries?
Volcanoes are formed. Sorry, that's all I know
What are ocean ridges formed by?
Divergent boundaries
What features form at divergent boundaries?
Trenches, mountains, islands, volcanoes, earthquakes, tsunamis
What landform are formed at a divergent boundary?
landforms associated with divergent boundaries are known as island arc orogeny and they lead to formation of islands and volcanoes along with trenches. example would be Japanese island, aleutian island etc.
Are divergent boundaries where new crust is formed?
That is correct.
A geologic feature of divergent plate boundaries in oceanic crust is the formation of?
rift valleys
What type of igneous rock is formed at divergent boundaries?
Who are you
Where are deep oceanic trenches found?
Trenches occur at convergent boundaries when one tectonic plate which is more dense, is pushed beneath another tectonic plate that is less dense. This process is called subduction. Usually where divergent boundaries in the earth's crust are. When faults move apart, they create trenches.<-- no divergent boundaries in the ocean create mountain ridges not trenches http://upload.wikimedia.org/wikipedia/en/a/a4/SubZone.jpg
