Answer:
The root of a huge tree causes cracks in a rocky surface.---> biological Weathering.
Part of a cliff breaks and falls due to waves.----> mechanical weathering
Acid rain reacts with calcite present in limestone---> chemical weathering
Explanation:
The root of a huge tree causes cracks in a rocky surface is the example of biological Weathering because in this weathering living organism is involved. Part of a cliff breaks and falls due to waves of water is the example of mechanical weathering because water enters the small pores of rocks and formed cracks when expands. Acid rain reacts with calcite present in limestone is a chemical weathering because acid present in rain water is responsible for the degradation and breakdown of rocks.
Here's the matching of the scenarios with the types of weathering:
1. The root of a huge tree causes cracks in a rocky surface - Biological Weathering
2. Part of a cliff breaks and falls due to waves - Mechanical Weathering
3. Acid rain reacts with calcite present in limestone - Chemical Weathering
Biological Weathering: In this scenario, the root of a huge tree causes cracks in a rocky surface. Biological weathering refers to the breakdown of rocks caused by the activities of living organisms. The roots of the tree can exert pressure on the rocky surface as they grow, causing cracks and eventually breaking apart the rock.
Mechanical Weathering: Part of a cliff breaks and falls due to waves. Mechanical weathering involves the physical breakdown of rocks into smaller fragments without changing their chemical composition. In this case, the force of the waves pounding against the cliff causes pieces of the rock to break off and fall.
Chemical Weathering: Acid rain reacts with calcite present in limestone. Chemical weathering involves the breakdown of rocks through chemical reactions. Acid rain, which is rainwater with a low pH due to the presence of acidic compounds, reacts with the calcite (a mineral in limestone) and causes it to dissolve, leading to the erosion and weakening of the limestone.
Each type of weathering plays a role in shaping the Earth's surface over time, and they often work together to break down rocks and minerals into smaller particles.

Answer:
One of the reason the countries wanted colonies due to industrial revolution was because of the natural resources this colonies could provide.
Explanation:
Industrial Revolution was a period in time between the 1700s and 1800s when there was a great turnaround in Industrialization in Great Britain first then it spread around the world. Industries started producing goods on a large scale.
There was a great advancement in Agriculture, Textile manufacturing and Electrical advancements as well.
Due to the Industrial Revolution, the industries in Great Britain start to expand and the economy was growing but there was shortage of raw materials. This made countries such as Great Britain to go in search of colonies because the colonies had an abundance of raw materials in form natural resources such as Cotton, Cocoa, Gold, Timber, Rubber which the industries needed in order to thrive well.
This led to the colonisation of countries like Africa, Asia and India.
