What are the two main characteristics for ALL igneous rocks?

Igneous rocks form from the cooling and solidification of lava or magma.

I'm not a big fan of this question, but I think the "desired" answer is grain-size (from very  large to microcrystalline) and interlocking texture.  

(It could be tendentiously argued that tuff (also called tufa) and possibly other pyroclastic rocks, which form from volcanic ejecta, lack an interlocking texture because they are more like sediments that are welded together. I say this is tendentious because such rocks are about as much sedimentary as they are igneous, and are not typical igneous rocks if they are igneous rocks at all.)

Label the following pictures with the type of erosion that formed it
aliina [53]

Answer:

The one on the top and right is water erosion, The one on the left is caused from a rock being there for so long is starts to become thinner because of the wind. Now the middle left is a natural basin that looks like water flowed through it so again water erosion. The middle right looks like the rocks and dirt fell off a mountain from being loosened from all the water,wind,humans and others so the kind of erosion is accelerated erosion. the bottom left is strong wind erosion. and the bottom right is a landslide. Hope this helps.

Consider these three squares, 25,144 and 169 . Can a right triangle be formed using these squares
e-lub [12.9K]

Answer:

Yes, if we take the square roots of 25, 144 and 169 (5, 12, 13)

Not by using those measures as is (sides of a triangle with 25, 144 and 169).

Explanation:

A right triangle is a triangle with an angle of 90 degrees, and the side facing that angle of 90 degrees is called an hypotenuse.

The hypotenuse measurement squared is equal to the squared measurements of the other two sides:

c² = a² + b²

And those squares do verify the equation:

169 = 144 + 25

So, that's a rectangle (right) triangle, with sides measuring 5, 12 and 13.

What was the motivation behind Europe's colonization of Africa?
Irina18 [472]

The main motivation of the European colonial powers to colonize Africa was the economic interest, or to put it more specifically, exploiting the natural resources, cheap and abundant labor force, and making wealth out of it.

Africa is a continent that is very rich in natural resources. Lot of those natural resources were very expansive, in high demand, and highly appreciated outside of Africa. The Europeans saw a great opportunity to make themselves even more wealthy, as they had far superior military and weapons, so conquering would not be a problem, and the natives were not using those natural resources nor knew that they are valuable in other places of the world.

The Europeans used the suitable circumstances, and numerous colonial European countries managed to get a piece of the African land, making lot of wealth out if it until the end of the colonial period.
