This type of plate boundary is responsible for mountain ranges, like those found in the himalayas
What are convergent (destructive) plate boundaries?
______ is the deterioration of rocks, soils and minerals through contact with water, atmospheric gases, sunlight, and biological organisms
What is weathering?

What is Earth's mantle?
_____ bands were one of the pieces of evidence used to help confirm Wegener's theory
What are fossil bands?
Transform plate boundaries usually result in this natural geologic event
What is an earthquake?
This is the name for the process by sediment is laid down by wind, flowing water, sea, or ice
The hottest and densest of Earth's layers
What is the inner core?
This is the name for the different sections of Earth's crust that move as a result of convection
What are tectonic plates?
The name of the plate boundary that is sometimes responsible for the formation of volcanoes and is also called a constructive plate boundary
What are divergent plate boundaries?
____ is the action of surface processes that removes soil, rock, or dissolved material from one location on the Earth's crust and then transports it to another location
What is erosion?
This layer of Earth is responsible for its magnetic fields
What is the outer core?
Wegener's theory is also known as the theory of _______ ____
What is continental drift?
This is the name for the geologic process in which a more dense tectonic plate descends into Earth's mantle
What is subduction?
