Above the tropopause is the stratosphere. This layer extends from an average altitude of 11 to 50 kilometers above the Earth's surface. This stratosphere contains about 19.9% of the total mass found in the atmosphere. Very little weather occurs in the stratosphere.
Cutting slate slabs does not have to be complicated; with standard tools and a suitable type of blade, you should be able to manage without a problem. Step 1 - Mark the Cutting Line and Mount the Slate Slab. Find the location on the slate slab that you want to cut and use a marker pen or pencil to draw a line across it.ou can also place it on top of two other slate slabs â anything to create a stable surface will do. The area of the slate slab marked by the pencil line should be places in the center between the two wooden or slate blocks. Step 2 - Cutting the Slate Slab. Get the circular saw and place a suitable blade in it.
The exposed surface of the cut slate is usually much longer that the lap of the ridge over the head of the slate so, in most instances, the slate will lever up the ridge tile and break or crack the mortar bedding. Even with dry-fix ridge systems, the ridge may not come off but can be levered over to one side.he batten that is located under the top edge of the slate is positioned about 25mm down from the top edge of the top of the slate so that it can only be seen in the V-shaped spaces between the slates. The top course of slates should now be cut such that the top edge finishes flush with the top of the slate below.
