Explanation

• When tectonic plates slide past each other, they form faults or fault lines.
• This type of plate boundary is called a transform boundary.
• Movement along fault lines can cause earthquakes.
• A famous example is the San Andreas Fault in California, USA.

Explanation

• A horst is an uplifted block of the Earth's crust formed between two parallel normal faults.
• It is created by tectonic forces during crustal extension.
• The adjacent blocks move downward, making the horst appear elevated.

Additional information:

• Graben: Down-faulted block between two normal faults
• Normal fault: Forms due to tensional forces
• Reverse fault: Forms due to compressional forces
• Strike-slip fault: Forms due to horizontal shearing forces

• Lahore's smog is mainly caused by pollutants from vehicles reacting with sunlight.
• Nitrogen oxides (NOₓ) and volatile organic compounds (VOCs) form ground-level ozone and fine particles.
• Industrial emissions, crop residue burning, and brick kilns also worsen smog.
• Smog is most severe during the winter season (October–January).
