Using the table below, classify each of the following rocks according to their mode of formation: marble, gabbro, dolomite, limestone, slate.

Here are the answers to the questions based on the image provided. i) horizon A: This is the topsoil, characterized by a high concentration of organic matter (humus), making it dark in color and rich in biological activity. ii) horizon B: This is the subsoil, where clay, iron, and aluminum compounds accumulate, leached from the A horizon. It is denser and has less organic matter than horizon A. iii) horizon C: This is the parent material, consisting of partially weathered rock or unconsolidated sediment from which the soil developed. It contains very little organic matter. iv) horizon D: This is typically the bedrock (R horizon), which is the unweathered, solid rock layer found beneath the C horizon. b) Classification of rocks by mode of formation: • Marble: Metamorphic • Gabbro: Igneous • Dolomite: Sedimentary • Limestone: Sedimentary • Slate: Metamorphic That's 2 down. 3 left today — send the next one.
