Rock Cycle
What is the process by which sedimentary rock can become metamorphic rock?
Heat and pressure
Describe how the movement of Earth's crustal plates can lead to earthquakes
Crustal plates build up stress and release it suddenly, causing earthquakes
Which layer of the Earth is primarily composed of solid iron and nickel?
inner core
How does the fossil record provide evidence for the theory of evolution?
It demonstrates a progression of species from simple to more complex forms
A well-tested explanation that unifies a broad range of observations
Theory
What type of rock is created when small pieces of rocks and organic material cement and press together?
Sedimentary rock
The thick part of the Earth's crust that forms the large landmasses. It is generally older and more complex than the oceanic crust.
Continental crust
Which of the following best describes the law of superposition?
What evidence supports the theory that Earth has evolved over geologic time?
The discovery of ancient rock formations and fossils
Explain how the inability of a species to adapt to a changing environment might lead to its extinction?
The species may not survive if it cannot adapt to new conditions
What type of rock is created when the texture, shape, or chemical structure is changed by heat and pressure
metamorphic rock
What is the primary cause of tectonic plate movement?
Heat flow within the Earth
how does radioactive dating help determine the age of Earth?
By analyzing the decay of radioactive isotopes
How do fossils provide evidence for the theory of evolution?
They reveal changes in species over time
What is a possible consequence for a species that cannot adapt to environmental changes?
The species may face extinction
How does heat flow within the Earth affect geological processes?
It drives the movement of plate tectonics
Describe how plate tectonics can lead to the formation of mountains
Plates colliding and pushing upwards
As you travel from the crust to the core, how would temperature, pressure, and density of the material change?
They would all increase
What does the theory of evolution suggest?
Species change over time
Describe the process of natural selection
The process by which individual with beneficial traits produce more offspring
What processes describes the action of breaking down rocks into smaller pieces and moving them?
Weathering and erosion
What type of evidence supports the theory of plate tectonics?
Similar fossils found on different continents
They transport heat and material, driving plate movements
Fossils are commonly found in a _________ in sedimentary rock. The _______ contain the older fossils. The layers nearer to the ______ are more recent. Fossils are used as one piece of evidence that supports the theory of _________.
Layers
Lower layers

Evolution
What is the term for a feature that allows an organism to survive better in its environment?
Adaptation
