Answer:
<u>Changes taking place in the environment of earth are measured through the climatic data of decades however the rate of depletion of natural resources with onset of man on earth, hense</u><u> 1.5 earths</u><u> are required to sustain the planet.</u>
Explanation:
- Various changes and disturbance caused in the earth history and environment that influences natural ecological processes, which not only encompasses physical changes but also the invasion of species and the catastrophic depletion of the environment.
- Taken as a whole the earth's sustainability over the years has fallen and due to massive growth in population size and driver of change is plate tectonics and volcanism, and solar radiation.
- Physical evidence can be seen in the form of greenhouse gases and depletion of freshwater resources use of artificial technology in agricultural practices.
- Some other impacts are ocean acidification, ozone depletion, species extension and rise in global temperatures.
This would be the legend!
The legend of a map tells you for example that a square means a capital city.
A scale shows you how big things presented on the map are in real life and the compass helps you orient the map with respect to the North.
A title helps you understand what the map focuses on (for example: " A Political map of Italy").
Answer: The name of the biome is Tundra.
Explanation:
Tundra is the coldest of all the biomes. Tundra comes from the Finnish word tunturi, meaning treeless plain. It is noted for its frost-molded landscapes, extremely low temperatures, little precipitation, poor nutrients, and short growing seasons. Dead organic material functions as a nutrient pool. The two major nutrients are nitrogen and phosphorus. Nitrogen is created by biological fixation, and phosphorus is created by precipitation.
Characteristics of tundra include:
Extremely cold climate
Low biotic diversity
Simple vegetation structure
Limitation of drainage
Short season of growth and reproduction
Energy and nutrients in the form of dead organic material
Large population oscillations.
Definition of Term:
Biome -
What is a biome? Biomes are very large ecological areas on the earth's surface, with fauna and flora (animals and plants) adapting to their environment. Biomes are often defined by abiotic factors such as temperature, climate, relief, geology, soils and vegetation.
Probably in the border nations just in case there was a war of some kind, if people needed to leave their country right away, they'll have enough time to get out of there.
