Gegraphy; Geologic HISTORY, Techtonic Plates, and Boundaries Flashcards
How many major geological eras are there?
Three: Paleozoic, Mesozoic, and Cenozoic
True or False: The Mesozoic Era is known as the ‘Age of Reptiles’.
True
Fill in the blank: The __________ is the supercontinent that existed during the late Paleozoic and early Mesozoic eras.
Pangaea
What are the three main types of rocks in the rock cycle?
Igneous, sedimentary, and metamorphic
Which geological era is known for the dominance of dinosaurs?
Mesozoic Era
What process describes the transformation of rocks through heat and pressure?
Metamorphism
True or False: The Cenozoic Era is often referred to as the ‘Age of Mammals’.
True
What evidence supports the existence of Pangaea?
Fossil distribution, geological formations, and climatic evidence
What type of rock is formed from cooled lava?
Igneous rock
Multiple Choice: Which era follows the Paleozoic Era? (A) Mesozoic (B) Cenozoic (C) Archean
A) Mesozoic
Fill in the blank: The process of __________ involves the breaking down of rocks into smaller particles.
Weathering
What is the term for the boundary where two tectonic plates meet?
Plate boundary
True or False: Pangaea began to break apart during the Mesozoic Era.
True
What is the main driving force of the rock cycle?
Plate tectonics and Earth’s internal heat
What type of evidence includes matching fossils found on different continents?
Biogeographical evidence
Multiple Choice: Which rock type is formed from the accumulation of sediment? (A) Igneous (B) Metamorphic (C) Sedimentary
C) Sedimentary
What is the primary agent of erosion?
Water
Fill in the blank: The __________ Era is characterized by the emergence of mammals and birds.
Cenozoic
What geological feature is created by tectonic plate movement?
Mountains, valleys, and earthquakes
True or False: The concept of Pangaea was first proposed by Alfred Wegener.
True
What is the significance of the fossil Glossopteris in supporting Pangaea?
It was found on multiple continents, indicating they were once connected.
Multiple Choice: The process of __________ involves the transport of sediments by wind, water, or ice. (A) Erosion (B) Deposition (C) Weathering
A) Erosion
Where does the main force(heat) that drives the rock cycle come from?
pressure, friction, and adioactive decay
What is the difference between Igneous and metamorphic rocks?
Igneous: Uses heat to form crystals
Metamorphic: Uses heat AND pressure to create or form bigger crystals
