Answer:1. answer: The law of superposition states that rock strata (layers) farthest from the ground surface are the oldest (formed first) and rock strata (layers) closest to the ground surface are the youngest (formed most recently).2. answer: So recently formed igneous rock is the youngest form of rock in most circumstances. Another major classification of rock, sedimentary rock, also forms from older rock and is younger as a result.3. answer: Fault J is cut by unconformity K so is older than K. Unconformity K is cut by intrusion G so is older than G, and intrusion G is cut by fault H so is older than H. Hence, fault H is the youngest.4. amswer: The principle of cross-cutting relationships states that a fault or intrusion is younger than the rocks that it cuts through. The fault cuts through all three sedimentary rock layers (A, B, and C) and also the intrusion.5. answer: Cracks in the soil in a river bank. Clumps of grass in the river. The top part of the river bank overhangs. Brown or coloured water.6. answer:
