MEASURING THE ADJUSTED DRAW LENGTH OF A BOW. The proper length for your arrow will depend upon several factors: the draw length of the bow, the type of bow you have, and the type & position of your arrow rest. Before we dive into this issue, we should briefly discuss how the draw length of a bow is measured.
The crust is the outermost layer of the Earth. It is the familiar landscape on which we live: rocks, soil, and seabed. It ranges from about five miles (eight kilometers) thick beneath the oceans to an average of 25 miles (40 kilometers) thick beneath the continents.ore Â». The Earth's interior is composed of four layers, three solid and one liquidânot magma but molten metal, nearly as hot as the surface of the sun. The deepest layer is a solid iron ball, about 1,500 miles (2,400 kilometers) in diameter.
Lesson 1 The Earth's Layers. 1  Crust -The outer layer of the Earth. 2  Oceanic Crust -Made of dense basaltic rock. 3  Continental Crust -Made of light granitic rock.  Mantle -Largest layer of the Earth located directly under the crust.
