Electromagntic wave, such as an X-ray.
Explanation:
- Electromagnetic wave does not require any medium to travel. These waves propagate outwards from the source.
- They can travel even through the vacuum of outer space.
- The major source is the sun which emits radiation in the form of the Electromagnetic spectrum.
- These waves travel through oscillating electrical and magnetic fields generated by the oscillating charged particles.
- These waves oscillate in the perpendicular direction of planes concerning each other and are in form.
- Electromagnetic waves travel at speed of light.
The basic theory of plate tectonics is that along seafloor spreading zones, the continents are separating from one another. As they spread apart, magma comes to the surface and becomes new continental crust. As the tectonic plates move away from spreading zones, they collide with one another.
Sandra is actually looking at the borders of the countries. The correct option among all the options that are given in the question is the first option or option "A". The dark lines separating each of the countries on the map of Europe are actually the borders of the countries in Europe. I hope the answer helps you.
Answer:
False

Hope this helps!
I might be wrong but I think the answer is
Continental deflection
