Chromium Ore Chromium is an important metal used to make strong alloys with other metals like nickel, cobalt, and copper. It is also used in various industries, including metallurgy and chemicals. Chromium makes these alloys stronger, harder, and tougher. Chromite...

Non-Metallic Minerals, Examples, Uses, Properties, Distribution Map

Non-Metallic Minerals Non-metallic minerals are minerals that do not have any metal elements. Since they lack metals, they are usually found in sedimentary rocks and younger folded mountains. Read More: Cobalt Ore Non-Metallic Minerals Examples Here are some examples of...

Tropical Climate & Tropical Monsoon Climate, Distribution, Map & Conditions

Tropical Climate The Tropical Region is located between the Tropics of Cancer and Capricorn. The northern limit of the region is formed by the Tropic of Cancer at 23.5°N latitude, and the southern limit is formed by the Tropic of...

Types of Winds, Planetary, Trade, Periodic, Westerlies & Diagrams

Types of Winds The Earth's surface heats unevenly because land warms up faster than water. This causes the air above the hot land to rise, creating a low-pressure area. Cold air from high-pressure areas then moves in to fill the...

Atmospheric Circulation, Definition, Factors, Three Model Cells

Atmospheric Circulation Solar radiation reaches the Earth and passes through the atmosphere, where it is absorbed or reflected. Most of this heat is absorbed by the Earth's surface warming the land and water. A small amount of heat from the...

Physical Weathering Definition, Types, Process, Examples & Diagram

Physical Weathering Physical or mechanical weathering is when rocks break into smaller pieces without changing their chemical makeup. This happens through processes like freezing and thawing, salt buildup, and heat causing cracks. The forces that break the rocks can come...

Biological Weathering Definition, Examples, Types, Causes, Agents

Biological Weathering Biological weathering is caused by living organisms. This type of weathering shows both physical and Chemical Weathering. For example, plant roots penetrate cracks in the rock and slowly break the rock mechanically. The plant roots secrete certain chemicals...

Chemical Weathering Process, Examples, Types & Diagram

Chemical Weathering Chemical weathering breaks down rocks through reactions between minerals and the environment. Here are some examples: Water: Water is the main cause of chemical weathering. It reacts with minerals like feldspar to form clay. Acids: Water contains weak...
