Have advances in agriculture improved the human condition, or have the benefits of the Green Revolution been limited to a few geographic regions?
Answer:
Yes, the benefits of the Green Revolution have been limited to a few geographic regions only.
Explanation:
In countries like the United States, Argentina, India, etc., the Green Revolution changed the picture of how agriculture yielded output by multiplying it owing to the advances in the methods of doing farming. Mechanized farming, hybridization of seeds, chemical fertilizers, etc., made farming more profitable in some parts of the world. On the other hand, the phenomena of the Green Revolution failed to work in most African and West Asian countries.Final answer:
The Green Revolution significantly increased global food production and reduced famine by introducing high-yield crop varieties and advanced farming techniques. However, it also led to environmental damage, social inequalities, and a dependency on unsustainable agricultural inputs. Critics emphasize the importance of smallholder farmers and call for a shift towards more sustainable practices.
Explanation:
Have advances in agriculture improved the human condition, or have the benefits of the Green Revolution been limited to a few geographic regions? Advances in agriculture, particularly those stemming from the Green Revolution, have had a profound impact on global food production, leading to significant increases in crop yields through the development of high-response varieties (HRV) of essential crops, expanded irrigation infrastructure, and the use of artificial fertilizers and pesticides. While these innovations have undoubtedly contributed to the reduction of famine and helped regions like China and India achieve self-sufficiency in basic foods, they have also led to several unintended consequences.
Increased reliance on chemical inputs and high-yield varieties has contributed to environmental degradation, loss of agricultural biodiversity, and has exacerbated social inequalities, particularly in developing regions. The rapid adoption of western, capital-intensive farming methods has favored large-scale operators and agribusinesses, leading to a widening gap between rich landlords and landless peasants, and escalating farmer debts in countries like India. Critics argue that the real backbone of global food security remains in the hands of smallholder and subsistence farmers, who are said to feed the majority of the world's population despite the focus on industrialized agriculture.

What is one form from which a rock can change and one form into which it can change?
Metamorphic rocks form from heat and pressure changing the original or parent rock into a completely new rock.
The parent rock can be either sedimentary, igneous, or even another metamorphic rock. The word "metamorphic" comes from Greek and means "To Change Form"
One form that a rock can change from is igneous rock to sedimentary rock.
How can rocks change ?Igneous rocks are formed from molten rock that cools and solidifies. Sedimentary rocks are formed from the accumulation of sediments, which are pieces of rocks, minerals, and other materials.
Another form that a rock can change from is sedimentary rock to metamorphic rock. Metamorphic rocks are formed when sedimentary rocks are subjected to heat and pressure.
Igneous rock can also change to metamorphic rock without going through the sedimentary rock stage. This can happen when igneous rock is subjected to heat and pressure.

Which are ways in which heat energy leaves the surface of land masses? Select the three correct answers.(2 points)
evaporation
glacial motion
animal activity
conduction to air, which then rises in convection
plant growth
radiation of infrared energy
Evaporation
Conduction to air, which then rises in convection
Radiation of infrared energy
Explanation:
Evaporation is a method where the water changes from the liquid stage to the gas stage. The liquid molecules will collide with each other when they are changing their phase. During this change, there will be a little energy transformation happening from one molecule to another. Conduction is the process at which the electricity or the heat transmitted through the medium when the difference in temperature occurs. In this process, the material is not moving. Convection movement will happen in gases and liquids because of their tendency to get hotter. Less dense molecules will go up and the denser molecule will come down which eventually transfer heat. Radiation is the energy emission in form of subatomic particles, electromagnetic waves and other high energy particles.The correct statement regarding the ways in which the heat energy so produced leaves the surface of land masses are by the ways of evaporation, conduction to air later rising in convection and radiation of infrared energy.
So, the correct options that match with the statements quoted above are A, D and G. These are the ways in which heat energy can be converted.
Heat Energy. Heat energy can only be transferred from one form to another, and it can never be created or destroyed. Evaporation refers to conversion of water or liquid bodies to the gaseous state.Conduction to air can be referred with an example that Sodium metal starts catching fire, which is a form of heat at normal room temperature. Radiation in the form of infrared energy refers to the transfer of heat energy due to waves that are passed through an object.Hence, the correct options are A, D and G that the heat energy leaves the surface of land masses by the ways of evaporation, infrared radiation and conduction to air.

List and explain four human activities that contribute to soil erosion
Answer:
1. Deforestation 2. Overgrazing 3. Overcropping 4.Construction
Explanation:
Soil erosion is exacerbated by human activities like construction, logging, agricultural practices including overgrazing and leaving fields bare, and recreational interests such as hiking and off-road vehicle use. These activities remove vegetation cover, making soil more prone to erosion by water and wind.
Soil erosion is a significant environmental issue exacerbated by various human activities. Four main human actions that contribute to this include:
Construction: This activity often involves stripping the land of vegetation, which increases the vulnerability of soil to erosion by water and wind.Logging: Trees stabilize the soil with their root systems. When trees are removed during logging, the soil is more susceptible to being carried away by erosive agents.Agricultural Practices: Methods such as overgrazing by livestock and leaving fields bare without cover crops result in the loss of natural vegetation that protects soil from erosion.Recreation: Recreational activities like hiking and off-road vehicle use can damage soil and vegetation cover, leading to increased soil erosion.It is crucial to adopt practices that minimize soil erosion, such as terracing, strip cropping, and replanting vegetation, to maintain soil health and prevent further degradation.
When did the build up of three oxygen create our ozone layer
Answer:
The build-up of three oxygen created our ozone layer around two billion years ago.
Explanation:
The ozone layer is a part of the stratosphere which is located right after the troposphere in the atmosphere of the Earth. The ozone gas is made up of the abundance of three oxygen molecules combining with the ultraviolet radiation emitted by the Sun. The development of the ozone layer happened around two billion years ago when the oxygen concentration levels on the planet began to rise slowly and gradually.y = X + 4 Y = -2x -2
The answer is x = -2 and y = 2.
Explanation:
The first equation can be written as x - y = -4The second equation can be written as 2x + y = -2step 1 :
Solving by elimination method to find the value of x and y,
x - y = -4
2x + y = -2
3x = -6
step 2 :
x = -6/3 = -2
The value of x is x = -2
step 3 :
Substitute x = -2 in any of the given equations.
⇒ y = x + 4
⇒ y = -2 + 4
⇒ y = 2
Which of the following igneous rock textures is most likely to have formed below Earth's surface?
glassy
aphanitic
phaneritic
Phaneritic
Explanation:
Igneous rock textures most likely to have formed below the earth's surface are termed phaneritic textures.
A rock texture is the arrangement of minerals in a mass of rock body.
During crystallization of melt, different texture attributes can be used to delineate the environment where a rock forms.
Rocks that cools beneath the earth crust are called intrusive igneous rocks. They allow for enough time for mineral grains to grow due to little nucleation centers forming at the same time.
Big grains of minerals gives the rock mass a coarse texture said to be phaneritic.
Extrusive and volcanic rocks usually forms glassy and aphanitic textures.
