4.
Many Processes on earth occur at or near tectonic plate boundaries. Which geological events are most common along tectonic plate boundries?
A. erosion and deposition***
B. hurricanes and tornadoes
C. earthquakes and volcanoes
D. tidal waves and sedimentation

Any way you can help me with them? I am not guessing,as you say.

0-0

4 is c

To determine the correct answer for question 3, we need to understand the given scenario. In this case, flood water is pounding against a canyon wall and wearing it down. This process describes the gradual removal or wearing away of materials, which is known as erosion (Option A). Therefore, the correct answer is A. Erosion.

For question 4, we are asked about the geological events most common along tectonic plate boundaries. To find the answer, we need to consider the processes that occur at plate boundaries. Tectonic plate boundaries are areas where two or more plates of the Earth's crust meet. These boundaries are associated with high levels of geological activity.

Among the given options, only earthquakes and volcanoes (Option C) are directly associated with plate boundaries. Earthquakes occur when there is a release of energy due to the movement of plates, while volcanoes are formed when molten rock (magma) from the Earth's mantle rises to the surface through plate boundaries. Therefore, the correct answer for question 4 is C. Earthquakes and volcanoes.

Both wrong. Stop guessing.
