Explain the "physical features" of the earth and give two examples. State any three activities that destroys mountain mountains.

Here are the answers to your questions:

1. Physical features of the Earth are the natural landforms and water bodies that make up the Earth's surface. They are formed by natural processes over long periods. Two examples of physical features are:

• Mountains: Large natural elevations of the Earth's surface rising abruptly from the surrounding level.
• Rivers: Natural flowing watercourses, usually freshwater, flowing towards an ocean, sea, lake, or another river.

2. Three activities that destroy mountains are:

• Mining: The extraction of valuable minerals or other geological materials from the Earth, which often involves removing large sections of mountains.
• Deforestation: The clearing of forests on mountain slopes for logging, agriculture, or development, leading to soil erosion and landslides that degrade the mountain structure.
• Construction of infrastructure: Building roads, dams, and settlements in mountainous regions often requires blasting and leveling parts of the mountains, altering their natural form.
