Plate Tectonics Flashcards
What is an endogenic process?
An endogenic process is a geological process that originates from within the Earth.
True or False: Endogenic processes include volcanic eruptions and tectonic movements.
True
Fill in the blank: Endogenic processes primarily involve ________ forces.
internal
What are the two main types of endogenic processes?
Volcanism and tectonism.
Multiple Choice: Which of the following is NOT an endogenic process? A) Earthquake B) Erosion C) Volcanism D) Mountain Building
B) Erosion
__________ are responsible for the movement of the Earth’s lithospheric plates, leading to earthquakes and volcanic activity.
Plate tectonics
True or False: Endogenic processes can lead to the formation of new landforms.
True
Name one example of a volcanic endogenic process.
Magma intrusions.
What is the primary energy source driving endogenic processes?
The heat from the Earth’s interior.
Multiple Choice: Which process is responsible for mountain formation? A) Erosion B) Weathering C) Tectonism D) Sedimentation
C) Tectonism
Fill in the blank: The movement of tectonic plates can cause ________ along fault lines.
earthquakes
What is the difference between endogenic and exogenic processes?
Endogenic processes originate from within the Earth, while exogenic processes occur on the Earth’s surface due to external forces.
True or False: All volcanic activity is considered an endogenic process.
True
A _________ is a location where magma from deep within the mantle rises to the surface, often creating volcanoes.
Hotspot
Multiple Choice: Which of the following is a result of tectonic plate convergence? A) Ocean ridges B) Rift valleys C) Mountain ranges D) All of the above
C) Mountain ranges
What is the role of magma in endogenic processes?
Magma is the molten rock that can create new landforms through volcanic eruptions.
What are the three types of tectonic plate boundaries?
Divergent, Convergent, and Transform fault boundaries.
True or False: Endogenic processes can contribute to the rock cycle.
True
What is subsidence in the context of endogenic processes?
Subsidence is the sinking of the Earth’s surface due to geological processes.
Multiple Choice: Which of the following phenomena is caused by endogenic processes? A) Landslides B) Tsunamis C) Earthquakes D) Floods
C) Earthquakes
What is an example of a geological feature formed by endogenic processes?
Volcanoes.
Fill in the blank: The theory of ________ explains the movement of the Earth’s lithosphere.
plate tectonics
What is the significance of magma chambers in volcanic activity?
Magma chambers store magma beneath the surface, and their pressure can lead to volcanic eruptions.
True or False: Endogenic processes can have a significant impact on the Earth’s climate.
True
What is the primary cause of volcanic eruptions?
The pressure buildup of magma in the Earth’s crust.
Deepest area in the ocean
Trenches
What type of endogenic process occur to make mountain ranges?
Continental to continental
What type of endogenic process occur to make a trench?
Oceanic to continental
What type of endogenic process occur to make island arc?
Oceanic to oceanic
Plates slide horizontally
Transform fault boundary
The plates move away from each other
Divergent plate boundary
Molten material from the mantle rises to the crust towards cracks in the ocean floor
Seafloor spreading
Old oceanic crust melts as it sinks back into the mantle
Seafloor spreading
Who discovered the seafloor spreading?
Harry hess
Hypothesized that new ocean floor was created at the ridge
Harry hess
Why did the plates move?
Caused by the convection current
