Earth science enthusiasts learn the names of soil layers in this geology worksheet. Students use a word bank to correctly label the five layers of the Earth's soil: humus, topsoil, subsoil, parent material, and bedrock. This worksheet makes a great addition to a second grade unit on geology. The ODNR Division of Parks and Watercraft manages Ohio's state parks and Ohio's boating program. There are 75 state parks in Ohio. Weathering grade III zone in granite cut-slopes often has open sheet joints or exfoliation joints which “daylight”, and hence is prone to failure. This paper discusses the engineering geology of rock slopes in relation to highways and roadways, the investigation and assessment of cut-slope stability, and provides some local case studies They were formed as black muds and sands settling on the seabed about 500 million years ago. They have since been raised up and crumpled and squeezed. These rocks are found mainly in the north of the National Park and the mountains they form are mostly smooth, though many streams have cut deep gorges.
