What is the weathering process by which softer less weather resistant rocks are worn away leaving more weather resistant rocks exposed?
The term erosion could be applied to the weathering of the surface of the earth. As water and the particulate matter it carries sweep over rocks, the softer ones will be worn away, will erode, more quickly than the harder ones. In the event of violent flooding when a massive increase in water flow churns river beds, rocks can be picked up and slammed together. Again it will be the softer materials that will be broken up more than the harder ones.
Can a harder rock erode more quicker then a softer rock?
No, harder rocks generally erode more slowly than softer rocks because they are more resistant to weathering and abrasion. Soft rocks tend to be more easily worn away by wind, water, and other environmental factors.
Why do different rocks weather at different rates?
Depending on the minerals in their composition, some rocks are harder than others. Rocks that contain minerals with higher ratings on the Mohs scale are harder, and would erode more slowly than other rocks.
Could rocks be soft o squishie?
No, rocks are typically hard and rigid due to their mineral composition and the way they are formed. Rocks can vary in hardness, with some being harder than others, but they are not squishy like softer materials.
Why do large round rocks erode faster than rocks with sharp corners?
Its actually more about the composition of the rock than the shape, the rounded rocks tend to be of a softer material such as sandstone, limestone etc which erode quicker and as such form into rounded shapes were harder rocks such as granite are more resistant to erosion and therefore its the softer materials that erode and leave the sharp edges of granite.
What is differental weathering?
The process by which softer, less weather resistant rocks wear away and leave harder, more weather resistant rocks behind
Why do harder rocks last longer?
Because they are able to resist erosion by wind, water and weather much longer than softer rocks.
How pedestal rock formed?
Pedestal rocks are usually formed in desert, when wind erosion wears away softer rock under-laying a harder rock. The harder rock is eroded at a slower rate than the softer rock.

What is it called when softer rocks wear away and leave harder rock behind?
What is it called when softer rock weathers away and leaves harder rocks behind
What is it when softer rock wear away and leave harder rock behind?
What is it called when softer rock weathers away and leaves harder rocks behind
How can differential weathering help you determine weather a rock is harder or softer than the rock that surrounds it?
Differential weathering causes rocks of different hardness to weather at different rates. If a rock is softer than the surrounding rock, it will weather more quickly, resulting in differential erosion that highlights the contrast in hardness. Over time, this pattern can help in determining the relative hardness of the rocks.
What is the process by which softer less weather resistant rocks are worn away leaving more weather resistant rocks exposed?
Erosion.
What is differential weathering?
Hard rocks , such as granite, weather more slowly than softer rocks , such as limestone. Differential weathering happens when softer rocks weathers away and leaves harder, more resistant rock behind. The figures below show an example of how differential weathering can shape landscape.
Is coal harder or softer than rock?
Coal is generally softer than most rocks. It has a lower hardness level compared to most types of rocks.
Can a harder rock erode more quicker then a softer rock?
No, harder rocks generally erode more slowly than softer rocks because they are more resistant to weathering and abrasion. Soft rocks tend to be more easily worn away by wind, water, and other environmental factors.
What is the significance of the Tees Exe Line?
It divides Britain into hard and softer rock types. The softer rocks in the south-east erode faster. In the north west are older harder rocks such as granite and basalt.
