Two processes categorized as sudden movementsQuestion 11AnswerA.Earthquake and volcanicityB.Erosion and depositionC.Compression and tensional

The two processes categorized as sudden movements are Earthquake and volcanicity. These are both geological events that occur suddenly, causing significant changes to the Earth's surface.

Step 1: Understand the question - The question is asking for two processes that are categorized as sudden movements.

Step 2: Identify the options - The options given are Earthquake and volcanicity, Erosion and deposition, and Compression and tensional.

Step 3: Evaluate the options - Erosion and deposition are slow processes that occur over a long period of time, so they are not categorized as sudden movements. Compression and tensional are types of stress that can lead to geological events, but they are not events themselves.

Step 4: Choose the correct answer - Therefore, the correct answer is Earthquake and volcanicity. These are both sudden movements that cause significant changes to the Earth's surface.
