My card was two invasive plants therefore I wont have 6 pictures.
1. The first part is the Western part that is covered by limestone . The area is a rock type that is nonresistant in the humid climate. The area has been worn down into a flat escape . The second part of Eastern Ohio is owned by sandstone which is a resistant rock while is under stain by a shale to the west . The Erosion of the sandstone is accomplishes by solution of the natural cement holding the grains together by water seeping down through the rock. The water seeds down though the rock giving it resistant character. The shale is much less resistant being worn down to low plains everywhere except where it is capped by the sandstone .
2. The original horizontal sequence of sedimentary rock strata in Ohio , a thick series of limestone layers overlain by shales which were in turn overlain by sand a thick series of limestone layers overlain by shales which were overlain by sandstones which was gently titles into a form of a low arch before erosion began. The arch was part a product of those pressures which approximal 200 years ago which created the Appalachian Mountains to the east. The oldest rocks were the limestone rocks which can be found throughout wester Ohio. The nonresistance has resulted in the erosion of the part f the state down to a nearly flat plain. The farthest east away from the crest which is the youngest rock layer which is the resistant sandstones were not removed, erosion having cut deeply into the rock strata but not having completely away resulting in the sandstones hills characteristic of this area typical of the Cleveland region where the sandstone is underlain by shale are the flat topped uplands held up by sandstone alternating with deep steep sided valleys cite into the under altering with deep steep sided valley cut into the underlying shale. Most of the erosions of all time limestone western Ohio and of the shale and sandstone in the east was by the famous preglacial stream they teays river . It was present 200 million years.
3. The glaciers were slowed down by the steep sided sandstone hills of eastern Ohio so the glacial boundary there is no farther south there is no farther south than the latitude of canton . On the board limestone plains of western Ohio where there was nothing to hinder the advance of the ice it extended as far south as northern Kentucky.
4. An unsorted mixture of sand slit clay and boulders is called till. In the westerns Ohio the glacial till is rich in lime and clay , products of the glacial abrasion of the limestone bedrock. In the eastern Ohio on the other hand most of the till contains very little lime and clay although near the margins of the area of sandstone hills where the ice moved from limestone bedrock onto sandstone the till is higher in both lime and clay then it is else where in the eastern Ohio.
5.On the plains of western Ohio the most common substrate is limy clayey till which provided a relatively soil, high lime but poorly drained and inadequate aerated. On the soil water does not soak in very fast but tends to remain on the surface creating low oxygen availably during wet periods and bad drouths during dry spells . The plant nutrients is abundant the glacial till is thin the condition encountered only locally the soil on the limestone is generally very shallow very high in lime and rich where it is not too thing but very dry due to excessive drainage down through the natural solution openings in the soluble limestone. In the eastern Ohio the very permeable sandstone bedrock where it is exposed produces a very acid low nutrient substrate which is especially dry on the tops of the hills. Locally the sand stone crops out a lower elevations . It also has acid where it provides a supply of moisture that is continually both available and cool because it comes rom springs, the waters is percolated down through the permeable sandstone and emerged deep in the valleys without being sun warmed . the shale present beneath the sand stone in some areas also produces a generally acid low nutrient substrate.
6. 5 species of trees/shrubs that have a distribution generally limited to limestone is hackberry, blue ash, red bud , red cedar and hawthorn
7. The common 5 are sugar male, beech, red oak, shagbark hickory , white oak and white ash.
8. Five species are chestnut, oak, sourwood and scuba pine and pitch pine
9. The distribution of sweet buckeye in Ohio is hachured line is glacial boundary and solid line separates area of limestone to west from area of sand stone to east. The distribution of hemlock is a glacial boundary and solid line separates area of limestone to west from area of sandstone to eats and the distribution of rhododendron is solid line represents positions of trunk stream and tributaries of teays river system
