The movement of tectonic plates causes a variety of geological changes, the most obvious of which would be earthquakes. These plates are pretty big, and when they scrape along the top of the earth, they can cause quite the seismological tremors.
Also, they can generate either trenches or mountain ranges along faults (the cracks between two plates).
Hope that helped =)

Answer:
Methods are given below.
Explanation:
1. Direct Imaging: Its directly seeing the planet itself, it's potential has increased dramatically over the past few years due to advancements in our technology.
2. Astrometry: Study of precise positioning of stars in the sky. The star is always much more massive than the planet, so the center of mass is much closer to the star, and thus the star's orbit is very tiny while the planet's orbit is much more pronounced.
3. Doppler Shift (also known as the radial velocity method) this method is based on the theorem that planet orbiting the stars have the same weight. The changes in the star spectrum and wavelength shows the brightness coming from the orbiting star.
4. Pulsar Timing: This Is a time-bound approach to finding the planets that orbit the stars through the beam of light that the old star emits.
