Natural Wonders Around the World
Introduction
Our planet is full of amazing places that look like they belong in a storybook. These Natural Wonders are created by Earth’s forces—like wind, water, and fire—and they teach us how the planet works. Let’s explore four spectacular wonders, learn new words, and even try a simple experiment you can do at home!
1. Majestic Mountains
What They Are: Huge landforms that rise high above the surrounding land.
How They Form: Most mountains are built by Plate Tectonics (the slow movement of giant slabs of Earth’s crust). When two plates push together, the crust crumples and lifts up, creating peaks such as the Himalayas.
Cause & Effect:
- Cause: The Indian Plate collides with the Eurasian Plate.
- Effect: The land is forced upward, forming the world’s tallest mountains and creating new habitats for animals like snow leopards.
Did You Know? The tallest mountain measured from sea level is Mount Everest (8,848 m), but if you measure from the ocean floor, Mauna Kea in Hawaii is taller!
New Vocab:
- Craton – a stable, ancient part of the Earth’s crust.
- Glacier – a slow‑moving river of ice that can carve valleys in mountains.
2. Deep Blue Oceans
What They Are: Vast bodies of salty water covering about 71 % of Earth’s surface.
How They Shape The World: Ocean currents act like a global conveyor belt, moving warm water toward the poles and cold water toward the equator. This Thermohaline Circulation (temperature‑driven water movement) regulates climate.
Cause & Effect:
- Cause: Sunlight heats water at the equator, making it lighter.
- Effect: The warm water flows toward the poles, cools, becomes denser, and sinks, driving deep‑sea currents that affect weather worldwide.
Did You Know? The Great Barrier Reef in Australia is the largest living structure on Earth and can be seen from space!
New Vocab:
- Salinity – the amount of salt dissolved in water.
- Biodiversity – the variety
