Hard rock is rock that doesn't wear away easily (resistent rock), therefore, soft rock is rock that does wear away easily.
i.e. that is way the coast is so uneven, because it hasn't got resistent levels of rock being continously hit by destructive waves.

Is sedimentary rock hard or soft?

Sedimentary rocks can be hard or soft. In the hard way it is
shaped as a crystal structure. Sandstones are hard though. SO its
hard and soft.
Further answer
Actually, sandstone may be hard or soft, depending on how it
came about. And none are crystalline apart from the small sand
crystals that are bound together to form the rock. Some sandstones
are so hard they are good for building. But some are so soft you
can wear them away with your finger. Although the sand particles
that got deposited are themselves hard, they are glued together by
different chemicals, some of which are very tenacious and make the
resulting rock hard. But some are not and the rock is soft. Same
with limestone, some is hard but some is very soft
Asked in Coastlines
What is a soft coastline?

Made up of clay and sands. Erodes quicker than hard rock which
is limestone or chalk. Not resistant to weathering and erosion.
Eroded quicker than hard rock which creates a bay and the hard rock
is called a headland. When you have hard rock then soft rock
alternating it is called a discordant coastline.

How waterfalls are formed?

The flowing water falls on the soft rock below, it wears it
away and hard rock from the top of the water fall falls on the soft
rock, as the hard rock falls from the top, it leaves a dent and the
water wears this away, then pushing the waterfall back, wooop
woop
A waterfall is formed when there is a layer of hard rock and a
layer of soft rock. The soft rock is eroded away first, so that the
harder rock just hangs over, creating a waterfall.
