Exogenic Process Flashcards
It is the process which occur on Earth’s surface due to the influence of exogenic forces.
Exogenic process
True or False: Exogenic processes are primarily influenced by internal Earth processes.
False
The main agents of exogenic processes.
wind, water, ice
It is the mechanical and chemical hammer that breaks down and sculpts rocks.
Weathering
Multiple Choice: Which of the following is NOT an exogenic process? A) Erosion B) Volcanism C) Weathering D) Sedimentation
B) Volcanism
Involves the movement of the weathered rock from their site of weathering
Erosion
True or False: Sedimentation is the process of depositing eroded materials.
True
What are the two main types of weathering?
Physical weathering and chemical weathering.
Fill in the blank: _____ weathering involves the breakdown of rocks without changing their chemical composition.
Physical
Multiple Choice: Which type of weathering involves chemical changes in the minerals of a rock? A) Physical B) Chemical C) Biological D) All of the above
B) Chemical
True or False: Exogenic processes can lead to the formation of sedimentary rocks.
True
Wind continuously blows away loose particles of rocks and soil from place to place.
Transport by wind
Rain water is the most important agent of erosion
Transport by water
Also known as mechanical weathering. It refers to the break down of rocks without change in its composition.
Physical weathering
True or False: Exogenic processes can shape landscapes over long periods.
True
What is the primary force driving exogenic processes?
Solar energy
Is the decomposition of rocks due to chemical reactions occurring between the minerals and rocks and the environment.
Chemical weathering
Multiple Choice: Which of the following is a result of erosion? A) Formation of mountains B) Creation of valleys C) Building of volcanoes D) None of the above
B) Creation of valleys
What is the role of vegetation in exogenic processes?
Vegetation helps to stabilize soil and reduce erosion, while also contributing to weathering through root growth.
True or False: Landslides are a type of mass wasting event.
True
_____ makes erosion complete because it involves the movement of the eroded materials and sediments.
Transport
Multiple Choice: Which of the following factors does NOT affect the rate of weathering? A) Climate B) Rock type C) Human activity D) Time
C) Human activity
What is the significance of soil in exogenic processes?
Soil is crucial as it supports plant life, retains moisture, and is involved in nutrient cycling.
True or False: Exogenic processes can lead to the creation of natural resources.
True
True or False: Exogenic processes are only relevant in certain geographical locations.
False
It is the chemical reactions caused by water.
Hydration/Hydrolysis
Multiple Choice: Which of the following best describes the term ‘sediment’? A) Solid rock B) Particles of organic matter C) Particles of weathered rock D) None of the above
C) Particles of weathered rock
It is the mixing of water and carbon dioxide to make carbonic.
Carbonation
True or False: Exogenic processes can be influenced by human activities such as agriculture and urbanization.
True
Also known as rusting.
Oxidation
The process whereby the rock minerals lose one or more ions or atoms in the presence of oxygen.
Oxidation
Changes in temperature and contribute to expansion and contraction of rocks
Thermal and pressure change
Tiny grains of sands are picked up and carried off by the wind which are then blasted on the surface of rocks is smoothening them.
Wind and waves
Trees and other plants can wear away rocks when their roots penetrate into the cracks in the rocks
Organic activity
