Scientific Study of Fossils and Plate Tectonics

Scientific Study of Fossils

• Paleontology is the study of fossils, the preserved remains of ancient organisms.
• This helps understand Earth's history.

Fill in the Blanks

• Subduction: The process of one lithospheric plate moving under another.
• Half-life: The time it takes for half of a radioactive substance to decay.
• Renewable resources: Resources that are naturally replaced and not depleted by use.
• Mohs scale: A scale used to measure mineral hardness.
• Plate tectonics: The theory describing the movement of Earth's lithosphere.
• Geology: The study of Earth's physical structure and substance.
• Solar energy: Energy resources derived from constantly replenished natural processes.
• Igneous rock: Rock formed from cooling and solidifying magma or lava.
• Permian-Triassic extinction: The largest mass extinction event in Earth’s history.

Plate Tectonics and Mountain Formation

• Mountains form at convergent plate boundaries when plates collide.
• The collision forces the Earth's crust upward, creating mountain ranges.
• An example is the Himalayas.

Importance of Conserving Nonrenewable Resources

• Nonrenewable resources (coal, oil) take millions of years to form and are limited.
• Conservation ensures future access and reduces environmental impact from overuse.

Mass Extinctions and Evolution

• Mass extinctions eliminate many species; the Permian-Triassic extinction was the largest.
• These events create opportunities for new life forms to evolve and thrive.
• The extinction of dinosaurs, for example, allowed mammals to become dominant.
