Detailed explanation-1: -A rock is composed of several large, rounded pebbles and sand grains cemented together.
Detailed explanation-2: -Conglomerate is a clastic sedimentary rock that forms the cementing of rounded cobble and pebble sized rock fragments. Conglomerate is formed by river movement or ocean wave action. The cementing agents that fill the spaces to form the solid rock conglomerate are silica, calcite, or iron oxides.
Detailed explanation-3: -Conglomerate is a sedimentary rock made of rounded pebbles and sand that is usually held together (cemented) by silica, calcite or iron oxide. It is a stone similar to sandstone but the rock particles are rounded or angular gravel rather than sand.
Detailed explanation-4: -Conglomerates. Conglomerates are clastic sedimentary rock that contains mostly pebble-size rounded clasts. The spaces between the clasts are generally filled with smaller particles and/or chemical cement that then binds and formed the rock matrices together.
Detailed explanation-5: -Conglomerate is made up of rounded pebbles (>2mm) cemented together. They are formed from sediment deposited by fast-flowing rivers or by waves on beaches.
