Rough - textured rocks have grains?
yes rough textured rocks do have grains.
Do lava rocks usually have large grains?
No. They are usually fine grained.No, lava rocks do not have large grains they have very small grains.
Which two rocks are made from rounded grains?
Rocks that are composed of rounded grains or fragments are usually sedimentary rocks. Two of these are sandstone and conglomerate rocks.
What are tiny rocks as small as grains of salt called?
Tiny rocks the size of salt grains are generally called, "Sand".
Are sedimentary rocks easily eroded?
YES! Sedimentary rocks, like sandstone, limestone and chalk can easily be eroded. This is because the grains in them (different to particles) are further apart to the grains in rocks like igneous rocks. This means that the grains can easily be crumbled off, and you get left with sand.
How are rocks and grains different?
rocks are formed from grains and grains are small and the rocks are big. Sedimentary rocks are formed when grains or sediments are compacted together.
Rough - textured rocks have grains?

Rough texture rocks have grains and fine textured rocks have grains?
Yes m that it true, other than glasses all rocks have grains.
Do lava rocks usually have large grains?
No. They are usually fine grained.No, lava rocks do not have large grains they have very small grains.

Where did the small grains of rocks come from?
Older rocks.
What kind of grains do rough textured rocks have?
large grains
Why are grains on the beach so small?
because sand was once rocks and the rocks got smashed to tiny grains of sand

Why do sedimentary rocks erode 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.
