Answer:
it has formed a parallel line
Explanation:
Parallel lines never intersect. Perpendicular lines are lines that intersect at a right (90 degrees) angle.
They both mean the same thing
So the answer is true

Regional volcanism is associated with mountain building.
Answer: Option D
<u>Explanation:</u>
Mountain building which is also known as the orogeny is the geological process such as movement of tectonic plates and volcanic activities because of which the mountains are formed by the pressure on the earth's crust when the plates collide.
So the occurring of volcanoes in a particular region along the plate boundaries where there is some movement in the tectonic plates might result in the formation of a mountain.
Answer:
It ranges from 2 to 13 km/s depends upon composition.
Explanation:
The velocity of seismic waves are different throughout the earth because of different composition of the layers inside the earth. Velocity of seismic waves increases with depth and it is approximately 2 to 8 km/s in the Earth's crust whereas, 13 km/s in the deep mantle so it means the velocity of seismic waves is higher in the mantle as compared to earth's crust due to different composition of layers between the mantle and earth crust.
