1) The Sun has an average surface temperature of approximately 6000 K. Calculate the power per unit area released by the surface of the Sun using Stefan-Boltzmann Law and report the value below. Units are a must. (2 points)Power per unit area released by the Sun=

Answer:

Explanation:

Ecology: It is the discipline of biology. It studies the interaction between the organisms and their interaction with their non-living physical environment.  It suggests that what factors influence the distribution and abundance of organisms.

Ecosystem: It is a biotic community in which living beings interact with their non-living physical environment. In other words the ecosystem is a place where living beings (biotic factors) interact with the non-living beings (abiotic factor).

Organism: An organism is an individual which belongs to a particular species or life form. An organism perform functions necessary to survive. It exhibit features of living being. The example of organism includes the plants, animals, fungi, and others.

Population: It is a group of members of the same species which are capable of reproducing and producing viable fertile offsprings. The population may vary in functional and morphological forms.

Community: A community is a group of two or more distinct species. These species interact among themselves so as to survive and performing functional roles in the ecosystem. For example, plants provide food to animals in return the animals disperse the seeds of the animals.

Answer:

Northern hemispheres are dominated by continentality than southern hemispheres

Explanation:

• Northern Hemisphere also called s the land hemisphere, due to this reason the northern part of the earth has more of temperature as the rivers and other bodies of water are dominant more in the southern hemisphere owning to this the southern face of the earth is cooler comparatively.

• Northern part experience heats more often due yo the influx of rivers and salinity raised by the continents as compared to that of the southern counterparts, which offer more mobility, and less salinity.

• The water hemisphere has only 1/8th of landmass covering 89% of the globe. Thereby experiencing strong horizontal winds in motion and cool geosynclinal patterns.

Answer:

C. Indian Ocean

Explanation:

• The phrase best describes the term precision agriculture is advances in information technology that improve farming

• One negative effect of advances in technology on the environment is increased pollution

• Technology has affected access to natural resources through increased access to resources

Precision Agriculture is simply known as as managementstrategy in agriculture. It helps to gathers, processes and analyzes data and also with other information to supportmanagement decisions through variability estimate so as to improved resource use efficiency, productivity, quality,and profit from farming.

Technologies are new advances or innovations. They have caused pollution and the depletion of natural resources.

such as excess of carbon dioxide, carbon monoxide, nitric oxide etc. in the atmosphere.

Conclusively, precision agriculture and new innovations has helped boast agriculture production.
