Spheroidal weathering and differential weathering are
sedimentary processes that sculpted the rock at Joshua
Tree after it formed. The primary rock
type at Joshua Tree is granite. What does the presence of
granite at Joshua Tree tell us about the geologic history of that
area? To earn full credit, you must demonstrate your
understanding of how granite forms by including the answers to the
following questions in your response:

How does an intrusive igneous rock, such as granite, form?
At what type of plate boundaries can granite
form? Hint: consider what type of plate boundaries might
create the conditions necessary for an intrusive igneous rock, such
as granite, to form.
