4. SPECIMEN A Forms no structure ------ SPECIMENC Forms aggregate Or lumps 5. SPECIMEN A is a Warmer Soil --------- SPECIMEN C is a Cooler Soil 6. SPECIMEN A has poor water retention --------- SPECIMEN C has water retention SPECIMEN D [PEBBLE OR SAND STONE] It is a sedimentary rock formed by settling of sediments SETTLING OF SEDIMENTS. The sediment are deposited in layers by agents like flowing water wind and Ice CHARACTERISTICS OF SPECIMEN D. 1.It Appears in layers 2.It has coarse texture 3.Presence Of Irregular fracture 4.Loosed Binding particles 5.Soft & Easily Breaked When Slight force is applied. SPECIMEN E [GRANITE] It is an igneous rock formed by molten magma. (SOLIDIFICATION ) from beneath the earth crust. It is the oldest known rock CHARACTERISTICS OF SPECIMEN E. 1.SHiny in appearance 2. Light Dark in Colour. 3. Coarsely crystalline in appearance 4.Has firmed binding particles 5.
