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.

Why is igneous rock so resistant to weathering and erosion?
An igneous rock is resistant to weathering and erosion because is is is made from magma. And magma rocks are really tough.
What are igneous rocks tend to be?
Resistant to weathering
Are igneous rocks easily eroded?
It depends on the type, but quite often they are not. Granite and basalt are erosion resistant. Some rocks formed by ash deposits, however, erode fairly easily.
Igneous rocks tend to be?
full of gold
What are rocks that are resistant to erosion called?
Cap rock. Resistant cap rock will help protect softer rock below it from erosion. Any rock type that is more resistant to erosion than the rock type below it is called a cap rock. For instance, it could be basalt (igneous) overlying limestone (sedimentary), or limestone (sedimentary) over shale (also sedimentary).

Which is older igneous or sedimentary?
Neither. You can get sedimentary rocks that are older than igneous rocks, or igneous that are older the sedimentary rocks. However, igneous rocks are formed from magma within the earth's crust, or as it extrudes onto the surface, while sedimentary rocks are formed from the erosion and redeposition of existing rocks, so generally in the life cycle of a rock the igneous form would come first.
How the igneous rocks change?
Igneous rocks change to Metamorphic rocks through heat and pressure. Igneous rocks change to sedimentary rocks through weathering and erosion until the igneous rock is sediments. The sediments then compact to form sedimentary rocks.

It is composed of harder rocks that resist erosion?
Igneous rock.
Which type of rock appear to be the least resistant to weathering and erosion?
Carbonate rocks, such as limestone, tend to be the least resistant to weathering and erosion.
What process helps change metamorphic and igneous rocks into sedimentary rocks?
Weathing and erosion.
Why is igneous rock more resistant to weathering then sedimentary rocks?
cos
What is the process by which softer less weather resistant rocks are worn away leaving more weather resistant rocks exposed?
Erosion.
