that the rock was moved by flowing water.
9.2 or, if you want to indicate that it is to the nearest hundredths, 9.20
6.50
76.5 is already rounded to the nearest tenth, which is more rounded than to the nearest hundredth. If you want to indicate that the number is accurate to the nearest hundredth, then write it as 76.50 otherwise leave it as it is.
479, rounded to the nearest thousandth is 479 although, if you wish to indicate that it is accurate to the nearest thousandth, you could write it as 479.000
The number is already rounded to the nearest million so you write it just as in the question. To indicate that it is accurate to the nearest 0.1 million, you could write it as 377.0 million.

Conglomerates are dominantly composed of rounded gravel and breccias are composed of dominantly angular gravel.
Could be conglomerate or breccia, depending on whether or not the clasts are rounded or angular.
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".
Conglomerates are sedimentary rocks where a fine grained matrix contains a large number of larger rounded pebble or rock sized clasts. These clasts are frequently pebbles made up from a variety of other rock types.
Yes, conglomerate is a sedimentary rock! It's a lithified mix of clasts, generally rounded to some degree, in a finer silt or sand matrix, all formed from deposits of the weathering products of earlier, often (but not exclusively) igneous, rock. If the clasts are coarse and angular the rock is a breccia.

If the rock formed in a turbulent stream then it would probably be called a conglomerate. These have well rounded clasts because the water has worn them down, as well as a large variation in the size of the clasts which is due to the high energy environment. If the rock formed in another high energy situation, such as a landslide, it could be called a breccia. It is a similar type of sedimentary rock to a conglomerate, however, its clasts are very angular rather than rounded because they are usually fragments of other rocks which have been broken during the high energy event.
They are referred to as clasts or bio-clasts.

Clasts are rock fragments, also pieces of rock that make up the texture of some sedimentary rock (clastic sedimentary rock).
