A treeless area between the icecap and the tree line of Arctic regions, having permanently frozen subsoil and supporting low growing vegetation such as lichens mosses and stunted shrubs
We exist because we all have a purpose, sometimes in life humans face challenges that contemplates past decisions and their future; they contemplate life. we exist to fulfill our dreams, without a dream, without a goal we can’t fulfill it. we exist from our mother womb, and born into a world of life. so to say “why do we exist” we exist to create dreams and goals. to fulfill them, to experience life.
Answer:
Options (2), (3), (4), and (7)
Explanation:
The factors that affects the number of deaths and the amount of damage caused by an earthquake depends upon the following things-
(1) Magnitude- The magnitude of an earthquake controls the amount of damage and loss of people. A high magnitude earthquake can cause greater damage in comparison to a low magnitude earthquake.
(2) Distance- The distance also plays an important role. When the distance from an earthquake is short, then the places nearby, at a certain radius gets affected very badly. Whereas, the places that are at a far distance, are not affected much by the earthquake.
(3) Depth- The depth of an earthquake depicts the epicenter distance. Shallow depth earthquakes are responsible for massive destruction. But, the deep focus earthquakes does not affect much unless it has a much stronger magnitude.
(4) Material that is used for construction of buildings- The type of materials that is used for construction purpose also is important. Weaker materials are easily broken down resulting in the collapsing of building. So, hard and resistant rock must be selected in order to maintain the stability of the buildings.
Thus, the correct answers are options (2), (3), (4), and (7).
Answer:
44,000,000 year
Explanation:
given data
modern rate = 2mm / 10 year
we consider here
himalayas elevation = 8.8 km
solution
we convert km into mm
8.8 km = 8800,000 mm
so
time for erosion will be
time = 8800,000 × 
time = 44,000,000 year
Answer:
B
. Areas near the equator get more direct sunlight so the temperatures are higher.
Explanation:
At equator, the sun is always over head and hits the surface directly. The surface is no at an angle to the sun.
The insolation here is very great and they received more direct sunlight.
- Due to the high insolation, the temperature is higher than most part of the earth.
- Rainfall levels are also high as rain cloud easily forms here.
- In most equatorial region, both temperature and rainfall is high all year round.
