Sedimentary rocks tend to erode easily compared to other types of rocks as the grains within them are farther apart than the "grains" in, let's say, igneous rocks. As a result of this, the "grains" can be easily crumble. An example of this is sand.

Is sedimentary rock made from solidified lava?
Rock that is formed from volcanoes are igneous rocks. Sedimentary rocks are formed from other layers of grains that are heaving and over millions of years have enough weight squish the grains into a proper rock. This is why the newest rocks are found at the top of layers.
What features of sedimentary rocks are unlikely to be found in metamorphic rocks what features of metamorphic rocks do not occur in sedimentary rocks?

What is the or-gin of sedimentary rocks?
weathering of preexisting rocks form clastic sedimentary rocks, Oversaturated water basins form chemical sedimentary rocks after the water evaporates and dead sea organisms settle at the bottom forming biochemical sedimentary rocks.
Are sedimentary rocks chemically weathered?
Sedimentary rocks can be both chemically and mechanically weathered.
Is sedimentary rocks formed the same way normal rocks are?
No, because a sedimentary rock is formed from pieces of other rocks.
Why do sedimentary rocks wear away faster than others?
Sedimentary rocks tend to erode easily compared to other types of rocks as the grains within them are farther apart than the "grains" in, let's say, igneous rocks. As a result of this, the "grains" can be easily crumble. An example of this is sand.
What type of rocks weather and erode to form sedimentary rocks?
all of them
Why do rocks erode at different rates?
Some rocks are harder than others like sandstone which is very soft. Other times rock can have different conditions under which they will erode faster such as limestone.
Rocks that erodes to expose layering is?
Rock that erodes to expose layering is known as sedimentary rock.
Does granite erode?
Yes, granite can erode, albeit very slowly, as it is a very srong, hard rock. All naturally occurring rocks will erode, given time
Why are some rocks more permeable than others?
Some rocks are softer and more sedimentary than others. This allows water to weather them faster, thus causing higher permeability.
What happens if water flows across rocks steadily for years?
The rocks erode and cause sedimentary rocks, such as shale. The river will most likely cut across the rock.
Can salt erode rocks faster?
Yes, because the ion chloride (Cl-) is corrosive.
Rocks formed from weathered debris from preexisisting rocks are called?
They are called clastic sedimentary rocks.
What is the process whereby softer sedimentary rocks erode more quickly than harder rock shaping the surface of the landscape?
Weathering and erosion.
Are sedimentary rocks classified tofoliated sedimentary rocks?
Metamorphic rocks are classified by foliation or lack there of, not sedimentary rocks. They are classified into Clastic Sedimentary, and Chemical Sedimentary.
When rocks are metamorphosed how do they change afterwards?
Metamorphic rocks can undergo further metamorphism through additional heat and pressure. They can also be melted, then cooled, and become igneous rock. They can also erode and become components of sedimentary rocks.
