Zoom in and look at Sample F in detail. This igneous rock contains at least 50% of a dark greenish grey mineral that has been identified as calcium rich plagioclase. There is also about an equal amount of a dark greenish black mineral that forms a texture of interlocking crystals with the plagioclase.

Answer 1

Answer:

a. pyroxene (augite)

Explanation:

Pyroxene is a mineral which is found in igneous and metamorphic rocks of the earth crust. They are dark green in color. their formation needs high degree of temperature and high pressure. Pyroxene is made up of silicon as a major element but some elements also present in it such as Ca, Na, Mg, Fe, Al and Ti. Its chemical formula is (Ca,Na)(Mg,Fe,Al,Ti)(Si,Al)2O6.

Discuss any five effective mechanism you will employ in ensuring sustainability sustainability of soil fertility in an area​

Answers

Answer:

Sustainability of soil fertility includes maintaining the nutrient's concentration in soil. Some of the effective mechanism to ensure sustainability of soil fertility in an area​ are as following:

Maintaining the process of crop rotation to ensure the fertility of the soil.Growing legumes for nitrogen fixation of soil rather than chemicals.Performing leaching in the crop rooting zone that will maintain flow of water and nutrients and minimize nutrient loss.Use of nitrogen-15 isotopic technique that determines the amount of nitrogen fixed in the soil and provides data on how much more nitrogen is required.The carbon-13 isotope technique is used to measure the contribution of different types of crops in the fertility of soil.

Hence, by taking the above measures soil sustainability can be maintained.

Answers

Answer:

It estimates the total energy released from an earthquake

Explanation:

The Richter scale was developed in the early half of the 1930s but seismologists from the US, namely, Charles Richter and Beno Gutenburg. The scale is essentially a logarithmic scale that calculates/estimates the largest peak of energy released during an earthquake. This peak is than proscribed a number from 1 to 10 on the scale with each number denoting the strength of an earthquake as 10 times the strength of the number below it. It accounts for movenent along the fault length (since that is essentially an earthquake) and the the Richter magnitude is calculated using a seismograph. Therefore, an earthquake that cannot be located on a seismograph cannot be incorporated on the Richter scale. There is no such directly proportionality between magnitude and amount of damage since a small earthquake in a densely populated area can cause way more damage than a strong earthquake is a desserted region. Furthermore, Richter scale determines the magnitude which impacts damage. Its not the other way round

Answer: a

4. Can you find two ways that carbon can get from the ocean to the lithosphere?
5. Describe at least two ways that carbon can get from seashells to the atmosphere.

Answers

Answer:

See it in the explanation

Explanation:

1) Carbon moves from atmosphere to hydrosphere and biosphere in the process of photosynthesis and to lithosphere by deposition of dead bodies while from hydrosphere and biosphere, carbon can be move in the process of respiration by animals.

2) During respiration process which takes place in plants in which carbondioxide is released and by eating carbon containing food by animals. By decomposing the food, carbon is releases in the form of carbondioxide.

3) Carbon can be used by the marine plants in the process of photosynthesis and during the process of diffusion, carbon is also dissolve in water bodies.

4) When the plants and animals die, the carbon which is present inside their body is buried in the soil present at the bottom of the ocean and the shells and corels of some animals also contain carbon which is soon be the part of the lithosphere when they die.

5) After the decomposition of seashell, carbondioxide is produced because shells are made up of calcium carbonate.

The carbon cycle refers to the movement of carbon throughout all spheres in the environment.

The carbon cycle is one of the biogeochemical cycles in nature. Biogeochemical cycles are cycles in which essential elements move through the different spheres of the environment.

Carbon enters the atmosphere through respiration of animals. Generally plants trap carbon dioxide from the atmosphere via photosynthesis. This is how carbon enters the biosphere. In the hydrosphere, oceans dissolve carbon dioxide as bicarbonate ions which serve as buffer in the oceans. This is how carbon enters the hydrosphere. Also rain drops dissolve carbon dioxide as it falls. Carbon enters the geosphere through decomposition of biomass.

Carbon gets to the land plants to the atmosphere when the plant dies, decays and carbon dioxide is produced. When plants are burn, carbon dioxide is also released to the atmosphere.

Carbon can move from the land to the atmosphere through combustion of matter and respiration of animals. Carbon can get from the atmosphere to the hydrosphere by dissolving directly into oceans or through rain water.

Carbon gets from the ocean to the lithosphere through the carbonaceous shells of some marine organisms and through fossil fuels and rocks that form in oceans.

Carbon can get from seashell to the atmosphere when the shells are burnt or the organism dies, decay and CO2 is returned to the atmosphere.
