This fault is produced when tensional stresses result in the subsidence of a block of rock. On a large scale these features are known as Rift Valleys . Graded Stream A stream that has a long profile that is in equilbrium with the general slope of the landscape. A graded profile is concave and smooth. Stream's maintain their grade through a balance between erosion , transportation , and deposition .
Erosion removes material from bumps in the profile and deposition fills in dips.
Gradient Wind Horizontal wind in the upper atmosphere that moves parallel to curved isobars . Results from a balance between pressure gradient force , Coriolis force , and centripetal force . Granite Medium to coarse grained acidic igneous rock that is rich in quartz and potassium feldspar . Derived from felsic magma . Granitic Magma Felsic magma that generates mainly granitic rocks .
