Question. Why are plains heavily populated?
Answer: Plains offer flat land, fertile soil, and easy transport, supporting intensive agriculture and large settlements.
Explanation: It's easy to build roads, houses, and farms on flat ground, so many people choose to live there.

Question. How do mountains influence climate?
Answer: Mountains cause orographic rainfall on windward slopes and create cooler temperatures at higher elevations.
Explanation: Mountains push clouds up so they rain, and their high peaks stay nice and cool.

Question. What is a vertical rock face or cliff?
Answer: A cliff is a steep or vertical rock face, often found along coasts or mountainous regions.
Explanation: A cliff is a tall wall of rock that drops straight down into the sea or a valley.

Question. What is glacial erosion?
Answer: Glacial erosion is the wearing away of land by moving glaciers, forming U-shaped valleys and fjords.
Explanation: Heavy, creeping rivers of ice scrape against rocks and carve smooth, deep valleys.

Question. How does an isolated volcanic island form?
Answer: A volcanic island forms when underwater volcanoes erupt and build up enough material to rise above sea level.
Explanation: Underwater volcanoes shoot out lava over many years until the rock peaks out of the sea.

Question. In what way do streams shape land?
Answer: Rivers erode, transport, and deposit sediments, carving valleys and forming floodplains and deltas.
Explanation: Rivers carve pathways through rocks and drop mud to build smooth, flat plains.

Question. How do landforms impact transport?
Answer: Flat plains allow easy roads and railways, while mountains require tunnels and passes, making transport harder and costlier.
Explanation: Building train tracks on flat plains is easy, but making roads across rocky mountains takes lots of tunnels.

Question. What is a river meander?
Answer: A meander is a broad bend in a river formed by erosion and deposition on alternating banks.

Question. How do landforms guide disaster planning?
Answer: Knowing landforms helps identify flood-prone plains, landslide-prone mountains, and cyclone-prone coasts so authorities can plan safe settlements and early warnings.
Explanation: Knowing the land helps us build homes in safe spots away from floods and landslides.

Question. What is a coastal plain?
Answer: A coastal plain is low-lying land next to the sea, often formed by sediment deposition and suitable for agriculture and settlements.
