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.
Answer:
I think that there are certain times in which it is a yes and a no. When you are looking at the family situation you really have to take into consideration what position everyone is in. I think that 16 is a good age to work, but that doesn't mean that they have to deprive their life. If everyone is really working together than that is a total yes. If on the other hand that parents aren't put a hand in it is never going to be the childs responsibility to provide for them. When you look at the situation for the kids sometime it is nice for them to learn the cost of money and real life. <3
The fourth event took place in the "Grand Canyon's" geologic history was "Dox Sandstone is deposited in a beach environment".
Option: B
<u>Explanation</u>:
The geological history of Grand Canyon located in Arizona, USA and involve full-sequenced rock studies on Earth. This arrangement is studied in the form of “ Unkar Group”, involve a layer of sedimentary rock named as “Stratum” from Proterozoic age which is branched into five geologic formations. This process is arranged in the following increasing order: Bass formation > Hakatai Shale > Shinumo Quartzite > Dox Formation > Cardenas Basalt. Here Dox formation is 4th portion which took place in Grand Canyon’s origination, which is a sandstone from Mesoproterozoic rock.
Fossil compaction is not a process which forms metallic ore whereas the other three ie placer processes, hydrothermal fluids and igneous processes all can help to form metallic ores. Placer does it by stream transport and separation of the heavy gold, and the fluids can carry metals and deposit them in the fractures in the solid rock and igneous processes like fractional crystallization can form a concentration of metallic ores also.
