Earth quakes are commonly found along fault lines or tectonic plates.

Answer:
With the increase in depth, age of layer increases.
Explanation:
According to the law of superposition, the layer of the Earth that is present in the deep is considered as the oldest layer while on the other hand, those layer which is present on the top of all layers is considered as youngest layer of earth. When we move from the top layer towards the bottom layer, the age of layer increases or in other words, when we move upward the age of the layer decreases so label the layers of earth on the basis of this phenomenon.
Answer: The correct answer is a.
Explanation:
Electromagnetic wave is a wave in which the magnetic field and the electric field are perpendicular to each other.
Both fields are directed in the direction of the propagation of the electromagnetic wave. It travels with the speed of the light.
The motion of the electric field produces both electric field and the magnetic field.
The electromagnetic waves are produced when an electric charge vibrates or accelerates.
Therefore, the correct option is (a).
Answer:
millisecond
Explanation:
Time is measured in seconds in the SI system. The scientist will measure the time it takes to complete one flap of the wings. In the SI system the use of prefix makes it easier to describe the value. It is as follows
Here, the wings flap so fast that the millisecond should be used.
That would be false.
Straight angle= 180 degrees
Obtuse angle= Above 90, and lower than 180
Acute angle= Below 90
Hope this helps! (:
