Answer:
I'm sure it Bb
Explanation:
because heterozygous means to be having two different alleles.
Answer:
<u>Olivines an Pyroxene, and 5 to 10% of calcium oxides and aluminium oxides</u>.
Explanation:
- The upper mantle of the earth begins just 10 kilometers below the surface of the lithosphere and under the ocean about 35 km and ends to the lower mantel at 670 km.
- Here the temperature range from 200 to 900 degrees celsius, at the boundary is composed of 55% of olivines and 35% of pyroxenes, minerals such as garnet and spinal are also found.
- Lehmann discontinuity is which is an abrupt change caused by the p and s waves occurs at the depth of 220 km. In the upper mantel and lower crust, there exists a discontinuity called the Gutenberg discontinuity.
- Mantel forms the rigid liquid sphere on which the slabs move.
The answer is actually pretty simple
Answer= 7.35 cm
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).
The northern sea route takes them thru artic waters and the water often freezes creating damage and delays
