Answer:
surfaces of uniform composition
Explanation:
- Air Mass is a volume of air characterized by temperature and water vapor content and stretched for 100 kilometers.
- Classified according to the latitude and the source regions, like cold air mass found in cooler polar regions and warm masses form over the hotter and drier regions of continents and maritime air mass are found at the seas and oceanic masses.
- As air mass differs based on there densities they have humid and temperature conditions and can be modified in various ways, an increase or decrease of temperature is also affected by the large scale environmental conditions.
Answer:
A. 3
Explanation:
A cone is a three dimensional shape with a flat base and curved surface. A right circular cone is a cone where the axis of the cone is the line meeting the vertex to the midpoint of the circular base.
The volume of a right circular cone = πr²h/3; where r is the radius of the cone and h is the height of the cone.
Let us assume the cone has a height of h, and radius of r. Hence:
Volume (V₁) = πr²h/3
If the radius remains fixed and the height is multiplied by 3. Hence:
V₂ = πr²(3h)/3 = πr²h = 3V₁
The volume would be multiplied by 3
Igneous rock derives it's name from the Latin word ignis which means fire. It is formed when the magma after volcanic eruption gets cool and solidified either on the surface of earth crust or inside the earth crust. These rocks are characterized by their hardness. These rocks undergoes no chemical weathering but exhibit very low mechanical or physical weathering may occur. Therefore, hardness is the property which can be used to identify the origin of an igneous rock.
The answer is A extreme proverty
Sub-Saharan Africa Relative to Other, Less Developed Regions
Sub-Saharan Africa is, by far, the region of the world with the highest level of mortality. Overall life expectancy at birth is 46 years, whereas in Asia, the region with the second lowest life expectancy, it is 67.
