Which type of rock appear to be the least resistant to weathering and erosion?
Sedimentary rocks like sandstone and limestone tend to be less resistant to weathering and erosion compared to igneous or metamorphic rocks. Their softer composition and structure make them more susceptible to the effects of these processes.
What are examples of rocks that are easily weathered and rocks re resistant to weathering?
Examples of rocks that are easily weathered include limestone, sandstone, and shale, which are sedimentary rocks. Rocks that are resistant to weathering include granite, basalt, and quartzite, which are igneous and metamorphic rocks that have a more crystalline structure and are less prone to chemical breakdown from weathering processes.
What rocks do not weather or erode?
Rocks that are resistant to weathering and erosion include igneous rocks such as granite and basalt, as well as metamorphic rocks like marble and quartzite. These rocks are composed of hard and durable minerals that are less susceptible to breaking down when exposed to the elements.
Which to rock units appear to be most resistant to weathering erosion?
Metamorphic rocks such as quartzite and marble tend to be most resistant to weathering and erosion due to their highly compacted and recrystallized nature. These rocks have undergone intense heat and pressure, which makes them more durable and less prone to breaking down compared to sedimentary or igneous rocks.
Why can intrusive igneous rocks be left behind when surrounding rocks are worn away?
Intrusive igneous rocks are formed from magma that cools and solidifies beneath the Earth's surface. They are more resistant to weathering and erosion compared to surrounding rocks, which are often sedimentary or metamorphic in nature. Therefore, when the less resistant rocks are worn away, the intrusive igneous rocks are exposed at the surface.
What is the process by which softer less weather resistant rocks are worn away leaving more weather resistant rocks exposed?
Erosion.
What is differental weathering?
The process by which softer, less weather resistant rocks wear away and leave harder, more weather resistant rocks behind
What type of weathering is a process by which softer less weather resistant rocks are worn away leaving more weather resistant rocks exposed?
Differential weathering
How get a waterfall?
The formation of waterfallsThe waterfalls are always formed at upper courses. The structure of rocks may be different, some are less resistant rocks, and some are resistant rocks.At the upper courses, no. of tributaries are few, the discharg is small and erosion is the main work at this. (espevially downcutting and headward erosion)Water does not erode the hard and resistant rocks, but the soft rock does. The less resistant rocks eroded at a faster rate. Strong hydraulic action and abrasion undercut the base of waterfalls, waterfalls formed.

How can you tell which rocks are the hardest when you look at a landscape from a distance?
The hardest rocks show the least effects from erosion and weathering and may cap a less resistant rock.
What are the main thing about rocks?
Sedimentary rocks are; 1. Stratified. 2. Composed of Fossils.. 3. Non-crystalline. 4. Generally less resistant to weathering.

Why are igneous rocks generally resistant to erosion?
They are resistant to erosion because they are more hard. They are like a piece of cement or trying to sand down the concrete floor it just wont happen.Thank You for asking wiki :)
