Consider the following statements:1. All natural earthquakes take plac...
Explanation:
Statement 1:
- The lithosphere is the outermost layer of Earth's surface that consists of the crust and upper mantle.
- Earthquakes occur due to the movement of tectonic plates in the lithosphere, leading to the release of energy in the form of seismic waves.
- Therefore, it is correct to say that all natural earthquakes take place in the lithosphere.
Statement 2:
- Earthquake waves are classified into three main types based on their propagation through the Earth: body waves, core waves, and surface waves.
- Body waves include P-waves (primary waves) and S-waves (secondary waves) that travel through the interior of the Earth.
- Core waves are also known as compressional or pressure waves and travel through the Earth's core.
- Surface waves are the slowest and most destructive waves that travel along the Earth's surface.
- Hence, it is correct to say that earthquake waves are basically of three types: body waves, core waves, and surface waves.
Therefore, the correct answer is Option C) Only 1, as both statements are correct.

Statement 1 is correct: Yes, all natural earthquakes take place in the lithosphere. The lithosphere is the outermost solid layer of the Earth, and includes the Earth's crust and the rigid upper part of the mantle.
Statement 2 is incorrect: Earthquake waves are basically of two types — body waves and surface waves. Body waves are generated due to the release of energy at the focus and move in all directions travelling through the body of the earth. There is no specific category called "core waves."
