Consider the diagram. A diagram is shown. A common ancestor splits into common ancestor and homo erectus. Common ancestor splits into homo neanderthalensis and homo sapiens. Which statement is supported by the diagram? Homo neanderthalensis is an ancestor of Homo sapiens. Homo erectus is an ancestor of Homo sapiens. Some ancestors can be on several branches in the hominids. Some ancestors of Homo sapiens have not yet been identified.

that would be called plucking : )

explanation:

''plucking, also referred to as quarrying, is a glacial phenomenon that is responsible for the erosion and transportation of individual pieces of bedrock, especially large "joint blocks". as a glacier moves down a valley, friction causes the basal ice of the glacier to melt and infiltrate joints (cracks) in the bedrock."

the correct answer is 4) heat and pressure

metamorphic rocks arise from transformation of existing rocks types, in a process called metamorphism. during metamorphism the original rock(prolith) change into metamorphic rock by heating (150-200c) and pressure of more than 1000 bar. the original rock can be sedimentary, igneous, or existing metamorphic rock.

the answer is c because it is most logical.
