Describe the asthenosphere?
Another name for the lower mantle is called the asthenosphere.
Most basaltic magmas are believed to form by partial melting of granite in the lower crust and upper mantle?
This statement would be considered incorrect. Basaltic magmas originate from the melting of mantle rock or oceanic crust.
What are the earths plates made of?

Is silica and forms of granite found in upper mantle?
Silica is found in the upper mantle, but not granite. Most of the minerals in the mantle are silicates, meaning they contain silica. Granite is found in the crust, primarily conditnental crust, as it forms from high-silica magma. The upper mantle is composed mostly of a lower-silica rock called peridotite.

What is thought to be common in the Earth's mantle but rare in the crust?
Peridotite is thought to be the dominant rock in the upper portions of the mantle. It's ultramafic, meaning it contains less than 45% silica.
Which of the Earth's layers is located just below the mantle?
Upper Mantlemantle
Is the second layer of the earth the upper mantle or the lower mantle?
upper mantle
Most basaltic magmas are believed to form by partial melting of granite in the lower crust and upper mantle?

What are the part of the mantle?
The upper mantle and the lower mantle.
