Explain the following geographical terms:

1. Rainforest
2. Intermontane plateau
3. Landlocked countries
4. Pacific Ring of Fire

1. Rainforest — Rainforest is a luxuriant, dense forest of hardwood evergreen trees found typically in tropical areas especially equatorial areas with consistently heavy rainfall throughout the year. They are renowned for their rich biodiversity.

2. Intermontane Plateau — Intermontane plateaus are surrounded by high mountains on all sides. The Andes consist of two or three parallel ranges with several intermontane plateaus lying between them. Notable among them is the Bolivian Plateau. It is the most extensive area of high plateau in the world after the Tibetan Plateau of Asia.

3. Landlocked countries — Landlocked countries are those countries that are entirely enclosed by land without any sea or ocean bordering them.

4. Pacific Ring of Fire — The Pacific Ring of Fire is a horseshoe-shaped zone around the edges of the Pacific Ocean known for its high volcanic and earthquake activity. It includes several tectonic plate boundaries where plates are colliding, sliding past, or moving apart, causing frequent earthquakes and volcanic activities surrounding the Pacific Ocean. Several peaks of the Andes are part of the Pacific Ring of Fire.
