1 Answer.
Factors related to deforestation
can lead to desertification in presence of natural drought.
Which of the following factors can lead to desertification?
Human activities that contribute to desertification include the
expansion and intensive use of agricultural lands, poor irrigation practices, deforestation, and overgrazing
. These unsustainable land uses place enormous pressure on the land by altering its soil chemistry and hydrology.
How is the environment affected by a large scale oil spill quizlet?
Large-scale oil spills are
damaging to water quality, aquatic life, and bird populations
. … Large-scale oil spills can lead to an increase in sea levels through glacial melting. C. Dryland planting can benefit the environment by reducing the need for tillage.
How can the practice of tillage be harmful to the overall?
However, tillage has all along been contributing negatively to soil quality. Since tillage fractures the soil, it disrupts soil structure,
accelerating surface runoff and soil erosion
. Tillage also reduces crop residue, which help cushion the force of pounding raindrops.
Which two layers of the atmosphere are responsible for the majority?
The majority of the mass of the entire atmosphere is contained in
the troposphere
—between approximately 75 and 80 percent. Most of the water vapor in the atmosphere, along with dust and ash particles, are found in the troposphere—explaining why most of Earth’s clouds are located in this layer.
Which is most likely long term effect of deforestation quizlet?
Continued deforestation will likely cause
the loss of plant and animals species
, resulting in an increase in the number of endangered, extinct, and threatened species.
What are 3 causes of desertification?
- Overgrazing. …
- Deforestation. …
- Farming Practices. …
- Excessive Use of Fertilizers and Pesticides. …
- Overdrafting of groundwater. …
- Urbanization and Other Types of Land Development. …
- Climate Change. …
- Stripping the Land of Resources.
What are the 3 main causes of desertification?
- Population growth – the population in some desert areas is increasing. …
- Removal of wood – in developing countries, people use wood for cooking. …
- Overgrazing – an increasing population results in larger desert areas being farmed.
What is the reason for desertification?
‘Climatic variations’ and ‘Human activities’ can be regarded as the two main causes of desertification.
removal of the natural vegetation cover(by taking too much fuel wood)
, agricultural activities in the vulnerable ecosystems of arid and semi-arid areas, which are thus strained beyond their capacity.
What could be one possible effect on human health due to an oil spill?
Studies of biomarkers have uncovered irreparable harm to humans exposed to oil and gas from spills. These effects can be grouped into
respiratory damage, liver damage, decreased immunity
, increased cancer risk, reproductive damage and higher levels of some toxics (hydrocarbons and heavy metals).
How is the production of mercury from burning coal an environmental hazard quizlet?
How is the production of mercury from burning coal an environmental hazard?
Mercury in water systems is transformed through biological processes into a substance that is toxic to animals.
Can large scale fires can lead to a decrease in atmospheric carbon dioxide?
Large-scale fires can lead to a decrease in atmospheric carbon dioxide. Environmental catastrophes can cause changes to the Earth’s surface.
What is the important of tillage?
Tillage has many roles in
crop production
, including seedbed preparation, seed placement, incorporation of nutrients and other amendments, and management of water and pests. Tillage also affects a variety of biophysical processes that impact the environment.
What is the advantage of tillage?
Tillage
loosens and aerates the soil
, which allows for the deeper penetration of roots. It controls weeds and mixes organic matter, fertilizer and manure with the soil.
What is the purpose of tillage?
Tillage is the mechanical manipulation of the soil with the purpose of:
Managing crop residue
.
Incorporating amendments
.
Preparing a seedbed
.
