Earth's layers
The layer of the earth on which all life is found.
What is the CRUST?
Plate boundaries that move toward each other.
What are CONVERGENT BOUNDARIES?
The type of rock formed by the cementation of sediments.
What is SEDIMENTARY ROCK?
The process by which rocks are broken down by wind, rain, ice, or roots.
What is WEATHERING?
True or False
Fossils can be remains or traces of organisms.
True
The layer of the earth made of molten iron and nickel.
What is the OUTER CORE?
Plate boundaries that move apart.
What are DIVERGENT BOUNDARIES?
The type of rock formed by heat and pressure.
What is METAMORPHIC ROCK?
The process by with sediments are moved.
What is EROSION?
Fossils are often found in this type of rock.
What is SEDIMENTARY?
The layer of the earth with the highest heat and pressure.
What is the INNER CORE?
Plate boundaries that slide past each other.
What are TRANSFORM BOUNDARIES?
The type of rock formed by melting and cooling.
What is IGNEOUS ROCK?
The process by which sediments are dropped off somewhere.
What is DEPOSITION?
The type of fossil that contains actual remains of an organism.
What is a BODY FOSSIL?
Two types of crust.
What are CONTINENTAL AND OCEANIC?
Mountain ranges such as the Alps are formed at this type of boundary.
What is a CONVERGENT BOUNDARY?
The only type of rock that is formed from an existing rock.
What is METAMORPHIC ROCK?
A glacier picking up and moving sediments is an example of which process?
What is EROSION?
What is a TRACE FOSSIL?
The type of crust that is thin and dense.
What is OCEANIC CRUST?
Mid-ocean ridges are formed at this kind of boundary.
What is a DIVERGENT BOUNDARY?
This type of rock may by shiny and glassy, or it may be rough, with crystals or air bubbles.
What is IGNEOUS ROCK?
The process by which river deltas are formed.
What is DEPOSITION?
Fossils found in deeper layers are (younger/older) than fossils found in less deep layers.
What is OLDER?
