Consider the following statements regarding 'Beaches': 1. They are characteristic of shorelines dominated by deposition. 2. Most of the sediment making up beaches comes from land carried by streams and rivers. 3. Beaches are permanent features that do not change with seasons. Which of the statements given above is/are correct?

The correct option is 1 and 2 only. Explanation Beaches are depositional landforms found along coastlines. They are formed by the accumulation of loose sediments, such as sand, gravel, and pebbles, primarily through the action of waves and currents. Statement-wise Analysis: - Statement 1 is Correct: Beaches are characteristic features of shorelines dominated by deposition. While they can occur as isolated patches along rugged, erosional shores, extensive beaches are formed where the accumulation of sediment exceeds the rate of erosion. - Statement 2 is Correct: The primary source of sediment for most beaches is terrestrial. Streams and rivers transport sediments from the land to the ocean, where waves redistribute them along the shore. Sediments also originate from the erosion of coastal cliffs. - Statement 3 is Incorrect: Beaches are temporary and dynamic features, not permanent ones. Their profile and composition change significantly with seasons. For example, high-energy storm waves in winter often erode sand, leaving behind coarser pebbles, while calmer summer waves deposit sand back onto the beach. Key Takeaway: Beaches are dynamic depositional landforms formed primarily from land-derived sediments transported by rivers; they undergo significant seasonal changes due to varying wave energy.

Solution

The correct option is 1 and 2 only.

Explanation

Beaches are depositional landforms found along coastlines. They are formed by the accumulation of loose sediments, such as sand, gravel, and pebbles, primarily through the action of waves and currents.

Statement-wise Analysis:

Statement 1 is Correct: Beaches are characteristic features of shorelines dominated by deposition. While they can occur as isolated patches along rugged, erosional shores, extensive beaches are formed where the accumulation of sediment exceeds the rate of erosion.
Statement 2 is Correct: The primary source of sediment for most beaches is terrestrial. Streams and rivers transport sediments from the land to the ocean, where waves redistribute them along the shore. Sediments also originate from the erosion of coastal cliffs.
Statement 3 is Incorrect: Beaches are temporary and dynamic features, not permanent ones. Their profile and composition change significantly with seasons. For example, high-energy storm waves in winter often erode sand, leaving behind coarser pebbles, while calmer summer waves deposit sand back onto the beach.

Key Takeaway:

Beaches are dynamic depositional landforms formed primarily from land-derived sediments transported by rivers; they undergo significant seasonal changes due to varying wave energy.

With reference to the stages of landscape development by running water, consider the following statements: 1. In the youth stage, streams are few with poor integration and flow over original slopes. 2. In the mature stage, waterfalls and rapids dominate the landscape. 3. In the old stage, divides are sharp and steep. Which of the statements given above is/are correct?

Consider the following statements regarding the erosional landforms of running water: 1. A gorge is a deep valley with very steep to straight sides and is almost equal in width at its top and bottom. 2. A canyon is characterized by vertical walls and is equal in width at its top and bottom. 3. Canyons commonly form in horizontal bedded sedimentary rocks, while gorges form in hard rocks.
