- Zeugen: These are tabular masses with a layer of soft rocks lying beneath a surface layer of more resistant rocks. The sculpting effects of wind abrasion wear them into a weird-looking 'ridge and furrow landscape.
- Mechanical weathering initiates their formation by opening up joints of the surface rocks. Wind abrasion further eats' into the under Irving softer layer so that deep furrows are developed.
- The hard rocks then stand above the furrows as ridges or Eugen and many even overhang. Such tabular blocks of zeugen may stand 10 to 100 feet above the sunken furrows. Continuous abrasion by wind gradually lowers the zeugen and widens the furrows.

Consider the following statements about Zeugen. 1. These are tabular ...
Zeugen are tabular masses found in certain landscapes. Let's analyze each statement to determine which ones are correct.
1. These are tabular masses which have a layer of soft rocks lying beneath a surface layer of more resistant rocks.
This statement is correct. Zeugen are composed of layers of rocks, with a layer of soft rocks beneath a surface layer of more resistant rocks. The differential weathering of these layers contributes to the formation of distinct tabular masses.
2. The sculpting effects of wind abrasion wear them into a weird-looking 'ridge and furrow landscape.
This statement is correct. The sculpting effects of wind abrasion play a significant role in shaping the appearance of Zeugen. Over time, the wind erodes the softer rocks more rapidly, creating ridges and furrows in the landscape.
3. Mechanical weathering initiates their formation by opening up joints of the surface rocks.
This statement is correct. Mechanical weathering, such as the opening up of joints in the surface rocks, initiates the formation of Zeugen. As water seeps into the joints and freezes, it exerts pressure on the rocks, causing them to crack and break apart. This process contributes to the formation of the distinct tabular masses.
Therefore, all three statements are correct, making option D the correct answer.
In summary:
- Zeugen are tabular masses with a layer of soft rocks beneath a surface layer of more resistant rocks.
- The sculpting effects of wind abrasion create a ridge and furrow landscape in Zeugen.
- Mechanical weathering, specifically the opening up of joints in the surface rocks, initiates the formation of Zeugen.
