Answer: A mafic lava cooling at earth's surface
Explanation: Basalt is the mafic igneous rock formed by the cooling of the magnesium rich and iron rich lava exposed area rapidly.It is mostly crushed for the purpose of using in construction projects. So,when mafic lava cools down on the surface of the Earth it forms basalt or basaltic lava . It is usually found in the form of columns on the Earth's surface.
Answer: The order are D-B-C-A-E
Explanation:
According to research of the Giant-impact hypothesis, Moon was formed by a giant Theia impact also called the Big Splash about 4.5 billion years ago and this started from the ejection resultant when a proto-Earth and a planetesima object of about the size of mars collided.
The formation of the moon are in this order below
---Earth undergoes differentiation--D
- A Mars-sized object collides with earth--B
- Debris collects in a ring around earth- C
- The debris collides to form single object--A
- The surface of the moon is smoothed out under its own gravity----E
I believe that the perpendicular equation would be the opposite sign and the reciprocal of the original slope. Then you just plug in the x and y coordinate to y=mx+b and solve for b.
y=4x+b
3=4(-4)+b
3=-16+b
b=19
y=4x+19
