Because some sedimentary rocks are made from different kinds of sediments.
No, pebbles are small, rounded fragments of rock that can be found within sedimentary rocks, but they are not considered sedimentary rocks themselves. Sedimentary rocks are formed from the accumulation and solidification of sediments over time.

Sedimentary rocks are made out of sediments.
Conglomerate and sandstone are rocks made from rounded grains. Conglomerate consists of larger, rounded gravel-sized particles cemented together, while sandstone is composed of smaller, rounded sand-sized grains cemented together.
Not necessarily. There is a special class of sedmentary rocks, called sandstones, which are dominated by sand-sized grains. Other sedimentary rocks, such as shale, contain much finer grains.
No, conglomerate is a sedimentary rock composed of rounded rock fragments cemented together. Clastic rocks are composed of individual grains or fragments of minerals or rocks that have been compacted and cemented together.
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.

Research has shown that it is not always very easy to identify sedimentary rocks with the naked eye. It has been stated that sedimentary rocks are porous and may contain small holes. Also, if one is to rub the rock and small grains tend to come off it might also be sedimentary.
Sedimentary rocks. and metamorphic rocks made form sedimentary rocks.
Look for signs of banding or layering that would be evidence of sedimentary strata. Banding also occurs in metamorphic rocks, but the bands may be very distinct in color from one another. If the rock scratches with a knife, it may be sedimentary. High silica content in some igneous rocks may prevent scratching with a knife blade.

Sedimentary rocks that formed organically typically contain calcite. Fossils are most likely to be found in sedimentary rocks.
