What is geomorphology?
Geomorphology is the scientific study of landforms and the processes that shape them.
True or False: Geomorphology only studies landforms on Earth.
False
Fill in the blank: The two main types of geomorphology are __________ and __________.
physical, historical
What is the focus of physical geomorphology?
Physical geomorphology focuses on the processes that create and modify landforms.
What does historical geomorphology study?
Historical geomorphology studies the evolution of landforms over time.
Which process is responsible for the formation of valleys?
Erosion
What is a landform?
A landform is a natural feature of the Earth’s surface.
Multiple Choice: Which of the following is NOT a type of landform? A) Mountain B) River C) Cloud D) Plateau
C) Cloud
What is the primary agent of erosion?
Water
True or False: Tectonic activity can create new landforms.
True
What role do glaciers play in geomorphology?
Glaciers erode land and shape landscapes through processes like plucking and abrasion.
Fill in the blank: __________ is the process by which rocks break down into smaller pieces.
Weathering
What is the term for the study of landforms and their relationships to the underlying geological structures?
Structural geomorphology
Multiple Choice: Which of the following landforms is formed by volcanic activity? A) Canyon B) Delta C) Volcano D) Plateau
C) Volcano
What is a delta?
A delta is a landform created by sediment deposition at the mouth of a river.
True or False: The Grand Canyon is an example of a landform created by river erosion.
True
What is the significance of the water cycle in geomorphology?
The water cycle is crucial as it drives erosion, sediment transport, and deposition.
Fill in the blank: __________ landforms are formed primarily by wind action.
Aeolian
What is the term for the process of landform change due to human activities?
Anthropogenic geomorphology
Multiple Choice: Which of the following is a process of mass wasting? A) Erosion B) Landslide C) Weathering D) Sedimentation
B) Landslide
What is a sinkhole?
A sinkhole is a depression or hole in the ground caused by the collapse of a surface layer.
True or False: Coastal geomorphology studies the processes affecting shorelines.
True
What is the difference between a river and a stream?
A river is generally larger and flows longer distances than a stream.
Fill in the blank: __________ is the process of transporting sediment by water.
Fluvial transport
