Identify the type of physical weathering occurring in this image.

Question

Describe what caused this type of weathering to occur in this rock

Answer 1

Since I cannot view images, I can provide you with general types of physical weathering and their causes. You can identify the specific type of physical weathering occurring in your image based on these descriptions:

1. Frost Wedging: This occurs when water seeps into cracks in rocks and freezes. When water freezes, it expands, exerting pressure on the surrounding rock. This can cause the rock to crack or break apart.

2. Thermal Expansion: Rocks expand when heated and contract when cooled. This process can lead to fracturing over time, especially in environments with significant temperature variations between day and night.

3. Exfoliation: This occurs in rocks that form under high pressure deep within the Earth. When these rocks are exposed at the surface, the reduction in pressure can cause them to expand and peel away in layers, similar to peeling an onion.

4. Abrasion: This occurs when rocks and sediment collide with each other, usually due to wind, water or ice movement. This can wear away rock surfaces over time.

5. Root Wedging: This type of physical weathering happens when plant roots grow into the cracks of rocks. As the roots grow, they exert pressure on the rocks, causing them to split or break apart.

To identify the specific type of physical weathering in your image, consider the characteristics of the rock and the surrounding environment. Each type has distinct features and processes that lead to rock alteration. If you can describe the rock and the conditions in the image, I can help you narrow it down further!

Answer 3

Continental mountains primarily form at convergent plate boundaries, where two continental plates collide.

Type of Plate Boundary:

• Convergent Plate Boundary (specifically "Continental-Continental Convergence")

Description of Plate Movement:

1. Collision of Continental Plates: When two continental plates converge, they push against each other because both plates are relatively buoyant and thick. Unlike oceanic crust, which can sink into the mantle due to its higher density, continental crust cannot easily subduct beneath another continental plate.

2. Crustal Thickening and Folding: As the plates collide, the immense pressure causes the crust to buckle, fold, and thicken. This can result in the formation of significant mountain ranges. The continual collision and compression can also generate faulting and uplift, contributing to the overall elevation of the mountains over long geological time scales.

This process is responsible for many of the world’s major mountain ranges, such as the Himalayas, which formed from the collision of the Indian Plate and the Eurasian Plate.

Answer 5

The process being demonstrated in the mantle is convection currents.

Explanation:

Convection currents in the mantle involve the movement of molten rock due to temperature differences. Hotter, less dense material rises toward the surface, while cooler, denser material sinks. This cyclical movement helps drive the movement of tectonic plates on the Earth's surface.

Answer 7

The correct statement that compares physical weathering and chemical weathering is:

Chemical weathering forms new substances while physical weathering does not.

Explanation:

• Chemical Weathering involves chemical changes that alter the mineral composition of rocks, leading to the formation of new substances (e.g., the formation of clay from feldspar).
• Physical Weathering (or mechanical weathering) involves the physical breakdown of rocks into smaller pieces without changing their chemical composition (e.g., freezing and thawing, abrasion).

Answer 9

Here’s how to categorize each process in terms of weathering type:

1. Exfoliation: Physical Weathering

   • Exfoliation occurs when layers of rock peel away due to pressure release or temperature changes, leading to mechanical fracturing.

2. Carbonation: Chemical Weathering

   • Carbonation involves the chemical reaction of carbon dioxide with minerals, leading to the dissolution of rocks, especially limestone.

3. Oxidation: Chemical Weathering

   • Oxidation occurs when minerals, particularly those containing iron, react with oxygen, leading to the formation of oxides and weakening the rock structure.

4. Frost Wedging: Physical Weathering

   • Frost wedging occurs when water seeps into cracks in rocks, freezes, and expands, causing the rock to break apart physically.
