Answer:
direct surface temperature measurements. changes in rainfall and weather patterns. an increase in the frequency of extreme weather events. loss of Arctic sea ice.
Answer:
Option (A)
Explanation:
A population density map is used to define as a map that shows the presence of a number of the population existing in any particular area. It directly reflects the dispersion of people that are mainly affected by environmental factors. This includes the variable amount of natural resources present in that area, the type of climate prevailing, the topography of the area and the availability of water resources.
The places which are rich in resources and low lying areas, with plenty of water resources and moderate type of climate are comprised of high-density population. On the other hand, the places which are highly elevated, lack of resources and extreme cold and hot climate are comprised of a lesser population.
Thus, the correct answer is option (A).
Answer:
True
Explanation:
Note the eye at the center.Skies are often clear above the eye and wind are relatively light.It is actually the calmest section of any hurricane.The eye is so calm because the now strong surface winds that converge toward the center never reach it.
Answer:
Explanation:
1 ) Humans are essentially tropical animals. A person will start feeling cold if temperature drops below 25 degree Celsius. Normal core body temperature of 37 degree Celsius above which they develop uncomfortable feeling which on higher scale can be life threatening. Humans do possess an efficient internal temperature regulating system which maintain optimum body temperature during extreme climates (hot and cold).
2 ) Human body readily adapts to the change in environmental conditions and can acclimatize to both hot and cold climate. Such extremities of condition like cold or hot induce adaptive behavior in humans. Such an adaptive behavior can be through change in genetic pattern of an individual, developmental adjustment, acclimatization and unique cultural practice. Example of two such behaviors that allows us to inhospitable climate is as follows,
(a) Cold Climate response: People dwelling in cold conditions traditionally consume more of alcohol which helps them to keep increased blood flow to the body extremities or vital organs, thereby providing warmth. Additionally they use insulating cloth, home and fires. Such conditions also induces biological responses like increased metabolic rate, fat insulation of vital organs and long term change in blood flow pattern.
(b) Hot climate response: Adapting to the hot climate is as complex to that of cold climate. During hot weather, physiological response such as sweating and its evaporation due to humidity helps body to cool down. Sweating is the only mechanism that effectively helps in cooling the body temperature. Yet another adaptive change that is frequently observed among the people residing in hotter climate is their body structures, which are generally leaner or thin.
The ground zone containing grasses is not a characteristic of the zones of a deciduous forest. The correct option among all the options that are given in the question is option "d". There is definitely a ground zone in the deciduous forest, but it consists of mostly true mosses, club mosses and lichens. The soil of these forests are very fertile in nature.
