Earthquake Wave Identification
Earthquakes generate different types of waves, known as seismic waves. Identifying these waves is key to understanding seismic activity.
Understanding Seismic Waves
Seismic waves are vibrations that travel through the Earth, typically as a result of an earthquake, volcanic eruption, or other explosion. The primary waves generated are:
- P-Wave (Primary Wave): These are the fastest seismic waves and can travel through solids, liquids, and gases. They cause compression and expansion of the material they pass through.
- S-Wave (Secondary Wave): These waves are slower than P-waves and can only travel through solids. They move material perpendicular to the direction of wave motion.
Given the options, the P-Wave is a fundamental type of wave generated during an earthquake.
Correct Option Analysis
- P-Wave: This is a correct classification of a seismic wave generated during an earthquake.
- N-Wave, O-Wave, Q-Wave: These are not standard classifications for seismic waves generated by earthquakes.
Therefore, the P-Wave is the correct answer.
Important Questions from Basics of Environment
The Wild Life (Protection) Amendment Act, 2022 seeks to implement the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES). Which of the following statements is correct about CITES?
1. CITES is an agreement between governments to ensure that international trade in the specimens of wild animals and plants does not threaten the survival of the species.
2. Under CITES, plant and animal specimens are classified into five categories based on the threat to their extinction.
3. The Convention requires countries to regulate the trade of all listed specimens through permits.
4. It also seeks to regulate the possession of live animal specimens.
