Why do harder rocks last longer?
Because they are able to resist erosion by wind, water and weather much longer than softer rocks.
Why are some rocks smooth and other are not?
Rocks become smooth through the process of weathering, which includes abrasion from wind, water, or ice over time. Rocks that are not smooth may have experienced less weathering or may be composed of harder materials that resist erosion. The smoothness of a rock can also depend on its location, as rocks in a riverbed or along a coastline are more likely to become smooth.
Is a hill of rock that resist weathering and erosion by a river?
A rock that resists weathering and erosion from a river is likely composed of durable rock types like granite or quartzite. These rocks can withstand the abrasive forces of the river's flow, leading to the formation of a hill or outcrop. Over time, the resistance of these rocks to erosion can create prominent features in the landscape, such as waterfalls or ridges.
A plateau has taken on its unique characteristics compared to the surrounding land mainly because?
of the geological processes that have occurred over millions of years, such as erosion, uplift, and tectonic activity. These processes have shaped the plateau's topography, making it different from the surrounding areas.
What are rock composed of weathered rocks called?
Weathered rocks that are composed of smaller fragments and grains are referred to as sedimentary rocks. These rocks are formed through the process of erosion, transportation, deposition, and lithification of the weathered materials.
Erosion can wear away which type of rocks?
Erosion can wear away all types of rocks, but it is more effective on softer rocks such as sandstone and limestone compared to harder rocks like granite and basalt. The rate of erosion depends on the rock's hardness, composition, and resistance to weathering.
What the definition of differential erosion?
Differential erosion occurs when a geologic area was formed of both soft and weak rocks rocks, are harder, more resistant, rocks, weak rocks wear away first leaving behind knobs and cliffs of more resistant rocks.
What is one factor which makes rocks more or less vulnerable to erosion?
One factor that can make rocks more vulnerable to erosion is their hardness. Softer rocks tend to erode more easily than harder rocks due to their weaker structure. This is because softer rocks are more easily broken down by the forces of weathering and erosion.
What are less resistant rocks?
Less resistant rocks include sandstone, chalk, and limestone. These rocks are more susceptible to weathering and erosion compared to harder rocks like granite and basalt.
What is a calcarenite?
A calcarenite is a form of limestone composed of sand-sized grains derived from the erosion of other rocks.

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
