Answer:
The two rock can be confused with each other as both appear rough to touch and both are found in shades of black & brown and dark themes, also shades of grey sometimes prevail.
They differ in the mode of formation as Quartzite is Metamorphic Rock while Basalt is the Igneous rock formed from the Volcanoes
Explanation:
The two rock can be confused with each other as both appear rough to touch and both are found in shades of black & brown and dark themes, also shades of grey sometimes prevail. They do have similarities in the hardness on some scale as Quartzite is hard while basalt is intermediate in hardness.
Major difference between them are:
They differ in the mode of formation as Quartzite is Metamorphic Rock while Basalt is the Igneous rock formed from the Volcanoes. Quartzite have medium grain size and foliated, granular structure while Basalt is fine grained and glassy in texture.
<span>What you describe is called devolution. This is when power is transferred to lower levels. When devolution occurs, autonomous regions occur and things like federations are created because numerous autonomous regions work together under federative rule, but still retain a great degree of independence.</span>
Answer: convergent plate boundary
Explanation: when a plate capped by oceanic crust is subducted under a continental lithosphere an accretionary wedge and fore-arc basin forms an active continental margin between the trench and the continent .the magma that is created by ocean-continent convergence forms a magmatic arc the surface expression of a magmatic arc is either a line of andesitic island such as Aleutian island .
S waves (surface waves)
