Which of the following indicates that different rocks in the same area might weather differently? Select the two correct answers. (1 point) Responses the rock atop a newly formed mountain the rock atop a newly formed mountain rock pillars in the middle of grassy plains rock pillars in the middle of grassy plains cliffs with ridges cliffs with ridges a smooth plain
The two correct answers that indicate that different rocks in the same area might weather differently are:
1. Rock pillars in the middle of grassy plains
2. Cliffs with ridges
To determine which of the options indicate that different rocks in the same area might weather differently, we need to understand the factors that influence weathering. Weathering refers to the breaking down or disintegration of rocks and minerals on the Earth's surface.
One of the key factors in weathering is exposure to the elements, such as wind, water, and temperature changes. Therefore, rocks in different locations or with different orientations may experience varying levels of weathering.
Let's analyze each option provided:
1. The rock atop a newly formed mountain: This option suggests that the rock is exposed to different weather conditions at higher altitudes. The increased exposure to wind and temperature changes may result in differential weathering.
2. Rock pillars in the middle of grassy plains: This option indicates that the rock pillars are exposed to open terrain, which may lead to different rates of weathering compared to rocks in other surroundings.
3. Cliffs with ridges: Cliffs with ridges have variations in elevation and surface features, indicating potential differences in exposure to weathering agents and consequent weathering rates.
4. A smooth plain: A smooth plain does not suggest any variations in geological features or factors that could lead to differential weathering. It implies uniform weathering conditions across the entire area.
Based on this analysis, the two options that indicate different rocks in the same area might weather differently are:
- The rock atop a newly formed mountain
- Cliffs with ridges
The two correct answers are:
- Cliffs with ridges: Cliffs with ridges suggest that the rock layers may be composed of different materials or have different resistance to weathering, leading to differential erosion.
- A smooth plain: A smooth plain indicates that the rocks in that area have likely undergone extensive weathering and erosion, resulting in a relatively uniform landscape. This suggests that the rocks in the same area can weather differently based on their composition and susceptibility to weathering.
