A. the creation of a new nation
B. the creation of a new state
C. a drastic boundary change
D. a small boundary change
Answer: He is witnessing a small Boundary Change.
A boundary change in geography is a change in a real or imaginary line or location.
The River was flowing towards the United States initially then changed towards Mexico. This is classified as a small change because he was tracking only a particular area of the
river.
Answer:
Tropospheric ozone is harmful, damaging plants and human health while ozone at the stratophere level screens out mutagenic ultraviolet radiation.
Explanation:
Ozone is dangerous and harmful in the lowest layer of the Earth's atmosphere. This layer is called troposphere. The reason why it causes damage to plants and human health it is because ozone is a reactive gas that affects plant synthesis and causes smog (a form of air pollution that is particularly dangerous to sensitive respiratory diseases such as asthma). However, ozone is helpful in the second layer of the Earth's atmosphere: the stratosphere. It prevents and blocks dangerous ultraviolet radiation.
Answer: 131
Explanation:
According to the Human Development Index, which is presented by the United Nations Development Programme (UNDP) every year, on 2020 India ranked 131 out of 189 countries. With an HDI value of 0.645, India fell in the medium human development category. Although India’s HDI is more than that of the South Asian region average (0.641) and is also above the average value of 0.631 among the medium HDI category countries, the HDI doesn´t include the inequality in the distribution of human development across all the people of India.
The folding of the Earth's crust could change the plant species that can survive in a location.
Explanation:
The movement of the tectonic plates is one of the primary factors that influence the creation and destruction of habitats. This is because this motion is able to change the landscape, create new crust, destroy old crust, lift or lower and area etc. When two plates collide, one feature that always occurs are the mountains, or highlands in general.
If an area was a lowland, and it gradually became a mountainous area, that will have big affect on the biosphere. The climate will be changed, the elevation too, the steepness of the terrain, the insulation and albedo etc. All of this will result in either adaptation of the plants to live in the changed conditions or spreading of plants that are already adapted for those kind of conditions. With the change of the plants there will be change of the species of animals, so over time the biosphere will be totally changed.
