. What is the importance of magma composition?

Most of the mantle and crust are solid, so the presence of magma is crucial to understanding the geology and morphology of the mantle. Differences in temperature, pressure, and structural formations in the mantle and crust cause magma to form in different ways.

How magma is formed?

Magma forms from partial melting of mantle rocks. As the rocks move upward (or have water added to them), they start to melt a little bit.As they rise, gas molecules in the magma come out of solution and form bubbles and as the bubbles rise they expand.

Answer:

Magma is extremely hot liquid and semi-liquid rock located under Earth’s surface. Earth has a layered structure that consists of the inner core, outer core, mantle, and crust. Much of the planet’s mantle consists of magma. This magma can push through holes or cracks in the crust, causing a volcanic eruption. When magma flows or erupts onto Earth’s surface, it is called lava.

The product of two consecutive numbers is 14 less than 10 times the smaller number. find each number
Helen [10]
The consecutive numbers are either 2 and 3, or 7 and 8..

x(x+1) = x^2 + x 
x^2 + x = 10x-14

quadratic form of x^2 + x = 10x-14:
x^2 - 9x + 14 = 0

(x-2)(x-7) = 0

x = 2, 7

so 2 and 3, or 7 and 8 are the answers

Step-by-step explanation:
The undefined terms in geometry are points, lines and planes.
A point's location on the coordinate plane is indicated by an ordered pair, (x, y). TRUE. In R², the ordered pairs (x,y) is used to defined the location of a point.
The second statement is false because a point has no dimension.
The third statement is also false because a line has only one dimension which is length.
The fourth statement is not true because distance between two points must have a beginning and an end.
A plane consists of an infinite set of points. TRUE .The plane is a home of infinitely many points.
