What are clasts?
Clasts are rock fragments, also pieces of rock that make up the texture of some sedimentary rock (clastic sedimentary rock).
What is a clast?
The main ingredients for most sedimentary rocks are "clasts". Clasts are solid fragments that have been weathered and eroded from other rocks that have been
Sedimentary clasts and grains become rounded primarily during what?
transportation
What is true about the texture of all detrital sedimentary rocks?
Clastic rocks have a 'clastic texture', which means they consist of clasts. The 3D orientation of these clasts is called the fabric of the rock. Between the clasts the rock can be composed of a matrix or a cement (the latter can consist of crystals of one or more precipitated minerals). The size and form of clasts can be used to determine the velocity and direction of current in the sedimentary environment where the rock was formed; fine, calcareous mud only settles in quiet water, while gravel and larger clasts are only deposited by rapidly moving water.[10][11] The grain size of a rock is usually expressed with the Wentworth scale, though alternative scales are used sometimes. The grain size can be expressed as a diameter or a volume, and is always an average value - a rock is composed of clasts with different sizes. The statistical distribution of grain sizes is different for different rock types and is described in a property called the sorting of the rock. When all clasts are more or less of the same size, the rock is called 'well-sorted', when there is a large spread in grain size, the rock is called 'poorly sorted'

What are rock or mineral fragments called?
Clasts. An accumulation of fallen clasts at the bottom of a rock face is "scree". An accumulation of clasts generally, up to about cobble size anyway, is a "sediment".
What are the small particles or the remain of living things that make up a sedimentary rock called?
They are referred to as clasts or bio-clasts.

What is the clasts is controlled by the ablity of a carrier to move them?
Size
What do rounded clasts indicate?
that the rock was moved by flowing water.
Sedimentary clasts and grains become rounded primarily during what?
transportation
What are the small pieces that rocks are made from called?
Grains, clasts, or detritus.
Rocks that have layers or clasts were formed by what?
Is it sediment being compressed until it becomes rock
Why is it difficult to dtermine the absolute age of a sedimentary rock?
In most cases, all we have to date are the clasts in the sedimentary rock. Dating the clasts, however, would yield the age of the source rock from which they were derived rather than the current sedimentary rock.
