During the ENSO cycle, in the Nino 3.4 monitoring region of the Equatorial Pacific, the typical sea surface temperature departure from normal is 6° C or more.
a. True
b. False
Answer:
b. False
Explanation:
During the ENSO cycle, in the Nino 3.4 monitoring region of the Equatorial Pacific, the variation in normal sea surface temperature is 3 ° C or less. This is because in the tropical pacific the surface water varies between 1 - 3ºC, which makes it impossible for the typical variation of the normal sea surface temperature to be 6 ° C or more.

20. How is a degree of longitude or latitude further subdivided? Give an example,
Answer:
Degrees of latitude and longitude can be further subdivided into minutes and
seconds (units of arc, not time): There are 60 minutes (') per degree, and 60
seconds (") per minute. For example, a coordinate might be written 65° 32' 15". ...
At the equator, it is approximately 69 miles, the same size as a degree of latitude.
For finding locations on the surface of the Earth, measurement lines called latitude and longitude are utilized. The degrees of a circle is used to express the angular measurements. The 360° that makes up a circle. 60 minutes can be divided into each degree, and 60 seconds can be divided into each minute.
What is the difference between longitude and latitude?The earth's center serves as the origin for measuring both longitude and latitude. Oriented to the east, a longitude is an angle measured from the prime meridian. Angular distance from the equator is measured by latitude (latitudes to the south are negative).
Locating locations on the surface of the Earth requires the use of measuring lines called latitude and longitude. They are angular measurements that are quantified in terms of circle degrees. A complete circle has 360°. There are 60 minutes in each degree, and there are 60 seconds in each minute.
Thus, Since latitude and longitude are angular distances, they are expressed in degrees (°). 60 minutes (') and 60 seconds (') are further separated into each degree.

Bioplastics made from corn grown using industrialized agricultural methods would have a smaller ecological footprint that bioplastics made from native prairie switchgrass.
A. True
B. False
Answer:
A this is true
Explanation:
i had to answer this question and i got it right
Bioplastics made from corn grown using industrialized agricultural methods would have a smaller ecological footprint that bioplastics made from native prairie switchgrass.
Thus, the correct option A.
What are Bioplastics?Plastics made from renewable biomass sources, such as plant fats and oils, maize starch, straw, woodchips, sawdust, and recovered food waste, are known as bioplastics.
Some bioplastics are made by processing polysaccharides (such as starch, cellulose, chitosan, and alginate) and proteins (such as soy protein, gluten, and gelatin) directly from natural biopolymers.
Other bioplastics are made chemically from sugar derivatives (such as lactic acid) and lipids (such as oils and fats) from either plants or animals, or biologically by fermentation of sugars or lipids.
Contrarily, conventional plastics like fossil-fuel plastics, often known as petro-based polymers, are made from natural gas or petroleum.
Bioplastics have the advantage of not requiring fossil fuel as a raw material, which is a limited and unevenly distributed resource with political and environmental implications.

why should be people living in developed countries be as concerned as people living in developing countries about climate change
Answer:
Developed countries have contributed 80% of the global warming as compared to the developing nations.
Explanation:
Climate and global warming are a global phenomenon and affect each and every nation differently, the rise of the surface temperature and rose of the sea levels all around the world impacts the settlements along the coasts. The increase of the greenhouse effects has led to the increase of the oceans becoming a carbon sink. The impact of climate change is felt in developed nations in the form of heatwaves, extreme weather patterns, and submergence of the coastland lands. Every year billions of dollars are wasted on food and water supplies. As of 2030 estimated global warming is expected to kill 250,000 people form malnutrition, malaria, diarrhea, and heat stress.Coal was created through the decomposition of ancient ___________.

Which depositional landform is created at the ultimate base level (or terminus!) of a stream, where sediment is deposited into the sea?
Answer:
Peneplain.
Explanation:
The base level is the lower limit of the erosional process and the ultimate base level is the plains that result from the projection of sea level under the landmass. This process of erosion creates a peneplain. The base level is dynamic and changes according to the following factors as sea-level changes, tectonic factors, river captures, and sedimentation. Peneplinasare low featureless deposits that are created by the terminus of the dream where the sediments are merged with the sea.What is solar system
After it experiences a "helium flash" a star like the Sun will have a brief period of stability, fusing helium into carbon (and sometimes oxygen). During this brief stable stage, the star:_________a. Increases tremendously in luminosity.b. Gets to be even larger in diameter than it was as a red giant.c. Returns to the position on the H-R diagram that the star had in its main-sequence stage.d. Is able to fuse many of the heaviest elements (such as iron and gold) in its superhot core.e. None of the answers provided is the correct answer
Answer:
a. Increases tremendously in luminosity
Explanation:
The helium flash is a thermal nuclear fusion with large quantities of helium gas into carbon. During the red giant phase, the sun is predicted to have a flash 1.2 billion after it leaves the main sequence and this helium fusion cannot be produced by the low mass stars. The sun in this stage will burn out or run out of its fuel and eventually will lead to gravitational collapse. The star being to shrink in size and core starts to collapse.New Faces, New Places: Mastery Test

Based on the population density maps above, what can be inferred about Britain’s migration patterns? A. The population of Britain was greater in 1701 than in 1911. B. Britain was more densely populated in 1911 than in 1701. C. Fewer people lived in urban areas in 1911 than in 1701. D. The northern part of the island was more densely populated than the southern part in 1701.
Answer: B. Britain was more densely populated in 1911 than in 1701.
Explanation:
In the map below, the darker colors are used to denote a heavier population density. Looking the map you will notice that there are more darker colors in 1911 then in 1701 which would mean that Britain as a whole was more densely populated in 1911 than in 1701.
This was down to Britain becoming a World Military and Economic power. These two factors meant that more prosperity was due to Britain which enabled it to reduce the mortality rate of its people in the so called Mortality Revolution.

In the case of Germany, you can make out the valley of the Rhine River, the industrial heart of Europe.
Answer:
Population.
Explanation:
U.S., India, and China, are the areas of heavy emissions of carbondioxide gas due to areas of dense population. These three countries have about half of the world population i. e. approx. 3 billions of people so vehicles and industries are high in number which releases the greenhouse gases such as carbondioxide and carbonmonoxide while heavy emissions of carbondioxide gas occurs from Germany because there is huge number of industries are there so that's why it is called the industrial heart of Europe.
The Ural Mountains exhibit a north–south orientation through Eurasia . How does the theory of plate tectonics explain the existence of this mountain belt in the interior of an expansive landmass?
Answer:
Ural Mountains have been formed by the collusion of plates during formation of Laurasia supercontinent.
Explanation:
The plate tectonic theory explains the origin of the different landmasses and the variation in different physical relief features over the globe. The Ural mountain ranges are those physical features that run north to south through the western Russia and they form a convection boundary between Europe and Asia. The form an extension of 2,500 km and are approx 1,895 in elevation. Their orology has been formed due to the collusion of the eastern edge of the Laurasia supercontinent with the continent of Kazakhstan and the intervening of the island arcs. This took place in the late Carboniferous period.What character motivation advances the plot?
