Answer:
A. It take up 71% of the earth's crust.
Explanation:
The oceanic crust makes about more than 70 percent of the oceanic landmass, having a thickness of 25 to 70 kilometers thick. Its the oldest of the crust on earth. Having an average density of 2,7 g/cm, primarily being composed of denser rocks like basalt and gabbro from below. Mostly it's basaltic, from here all sorts of rocks are recycled to the outer land surface of the earth. Accounting for nearly 60% of the global slab of plates. Apart from this, the seafloor is covered with volcanic necks, trenches and deep-seated volcanoes that produce magma and the oceanic floor is composed of layers of rocks that date back to the various epi, meso, bathy, and abyssopelagic divisions.Which location shows signs of having spread the fastest during the period 60–70 m.y.a. (million years ago), and how many kilometers of new crust were formed during that period?
Answer:
North america
Explanation:
By 65 million years ago ie. the end of the cretaceous era and beginning of the Cenozoic era, the water still covered the landmasses and India and Australia was still not separated. Spreading up of plates and the opening of land boundaries was massive at this time hence the crust formed at this time was the fastest and continued to from as the mountain began to appear and the shrinking up of the oceans. Movement of Asia and break up of the pacific ocean created, which were accompanied by the climatic and changes in weather patterns.Canada and Australia are (mainly) English-speaking countries with populations that are not too different in size (Canada's is 60 percent larger). But Canadian trade is twice as large, relative to GDP, as Australia's.
Why should this be the case?
Answer:
Canada and Australia being located on both other ends, thus have a wide travel duration. Canada is richer than usa.
Explanation:
Canada is currently the second-largest goods trading partner of the U.S, China, and the U.K in terms of export and imports with a total trade of $617.2 billion. The goods export trades totaled to $298.7 billion, while goods imported totaled to $318.5 billion. Canada is n the northernmost part of the world experience high trade volumes and this is mostly due to the nearby countries as Australian country is located far south it does not have a large trading partner so the amount of the trade participation is less. Time taken for the goods to get delivered and deposited is also more as compared to the American and Canadian standards.The first European settlements along the coast of sub‑Saharan Africa included St. Louis, Luanda, and Lourenço Marques (now Maputo). From what country did the settlers come?
Answer:
Portugal
Explanation:
The earliest European settlements along the coast of Sub-Saharan Africa Settlers and explorers where from Portugal for the exploration of oceanic routes and island groups around Africa. The 15th century marks the age and exploration of Sub Saharan Africa, under Henry the Navigator who went to St. Louis, Sunanda, and Lourenco, etc. After which came the Dutch to colonize Africa. The cape code remained under the dutch rule till 1803, after which the Britishers took over from 1806. All these came from European countries and tried to settle in Africa as it was wide and full of resources.All of the following provide evidence or clues to the composition of Earth's interior except for ________. a. comets b. diamond-bearing rocks c. meteorites slivers of crustal and d. mantle rocks now exposed at Earth's surface
Answer:
The answer would be A.
Explanation:
It would be a because comets orbit around the sun and has a very small chance at crashing into the Earth.
All of the following provide evidence or clues to the composition of Earth's interior except for comets
Answer: Option A
Explanation:
Comets are the celestial bodies which comprise of four components: a nucleus, a dust tail, a coma and an ion tail. Comets are also known as dirty snowballs or cosmic snowballs.These bodies orbit around the sun in elliptical paths just like the other planets of the solar system. Since they orbit around the sun, there are very few chances that they will be a part of the earth's interior.
Diamond-bearing rocks and mantle rocks are volcanic rocks that start somewhere down in the Earth and are emitted onto the surface. Numerous meteorites are little and alluring enough to be utilized as pearls in a similar condition in which they tumbled from the sky.

Answer:
is suffering from dehydration
Explanation:
When the environmental temperatures, the human body needs more water because the rate at which it looses water is faster in comparison with winter days.
Water is the most basic liquid that our body needs to work efficiently. There are different effects of the water lost like headaches, dry mouth, dry skin, etc.
Headaches is one symptom, since the brain is covered practically with water, when doesn´t have enough liquid it starts to receive the signal and in response pain is release.

Light elements like hydrogen and helium form a large percentage of the outer planets and Sun is made up primarily of hydrogen. Why are these elements nearly absent from the inner planets?
Answer:
Instead of Helium and Hydrogen there are heavier elements in inner planets like Nitrogen and oxygen.
Explanation:
As the inner planets like Mercury, Venus and Mars and earth have a solid surface which is separated by the Sharpe atmosphere, and their gravity is too low to hold these light gases. Uranus is primarily composed of gases and ice of which 83% is hydrogen and 15% helium and rest are trace gases. As in the early composition of the atmosphere, the inner planets like the earth had a solid atmosphere composed of solid silicates elements like magnesium, iron, calcium, and potassium. As the earth has a highly unstable atmosphere only carbon, nitrogen and oxygen combined in lightning occur. And planet mercury has no atmosphere thus gravity is too low to hold any gas.The mysterious Dark Energy is slowing the expansion of the universe. is believed to be the dominant form of energy in the universe. is attributed to the gravitational force of black holes. was suggested by the unexpected rotation speeds of galaxies
Answer:
The dark matter is a dominant form of, energy often associated with black holes
Explanation:
Dark matter or dark energy constitutes about 85% of the universe and about a quarter of its energy density. Its ai called so as it does not tend to interact with observed electromagnetic radiation, such as light and thus invisible to the spectrum. Gravitational lensing is a technique defined to prove the existence of the dark matter in the universe, in a black hole generally the entire star mass collapses and forms finite amounts of time. The evidence got from the rotational curves shows that dark matter in the center dominant position rotating galaxies like the spiral galaxies. Which the passage of time these galaxies speed of formation has slowed down and as galaxies spread and widen the rate of spread of dark matter also slows the rotation of galaxies.How many degrees of longitude are there in one hemisphere

A. lumpy accumulations on the seafloor.
B. precipitates from groundwater that have dissolved lead and zinc at depth, then transported them to the surface.
C. alternate beds of gray iron oxide and red lenses of jasper.
D. residual mineral deposits in soil that have everything leached out but the aluminum.
Answer:
The correct option is: D. residual mineral deposits in soil that have everything leached out but the aluminum
Explanation:
Bauxite is a type of sedimentary rock that is rich in aluminium. Bauxite is known as the world's primary ore for aluminium and main source of gallium, which is a rare metal.
Bauxite is produced majorly in Australia and China. It is formed from laterite soil and is commonly found in subtropical or tropical regions.
Because we live in an expanding universe, distant galaxies are farther away from us today than they were when the light we see from them started on its journey to us. So what do we mean when we say that a galaxy is 7 billion light-years away?
Answer:
There light has taken 7 billion years to reach us.
Final answer:
A galaxy said to be 7 billion light-years away from us is a measurement of the time light has traveled to reach Earth, showing us the galaxy as it was 7 billion years in the past due to the constant speed of light.
Explanation:
When we say a galaxy is 7 billion light-years away, we are describing the distance light has traveled from that galaxy to reach us. As light travels at a constant speed of over 186,000 miles per second, one light-year refers to the distance light can travel in a year.
Thus, the light from a galaxy that is 7 billion light-years away has been on its journey for 7 billion years.
This means we are observing the galaxy as it was 7 billion years ago; since the universe is expanding, the galaxy is likely at a greater distance now. When we look at distant galaxies, we are essentially looking back in time and can observe changes that have occurred over billions of years, such as galaxy mergers or the evolution of stars.
The Andromeda galaxy, for instance, is 2 million light-years away, which allows us to see it as it was 2 million years ago.
Observing galaxies billions of light-years away gives us a glimpse into the universe's past and allows us to study its evolution. Yet, this comes with challenges due to the great uncertainties in our data and makes cosmology a field with both many questions and some significant discoveries, characteristic of a golden age of exploration.

What causes two distinct pressure zones between the equator and the poles? . . A. The troposphere interacts with the mesophere. B. The ozone layer. C. The fact that nitrogen is heavier than oxygen . D. Earth's rotation .
Answer:
D. Earth's rotation
Explanation:
The Coriolis force, cause distinct pressure zones between the equator and the poles due to the spinning of the earth on its axis. This force directs the winds on the right side in the northern hemisphere and directs them in the left side in the southern hemisphere. This force is the cause and consequence of the earth's internal inertia. Friction force causes it to be actively seen in motion. Compared to other force Coriolis force is smaller and it only deflects the pressure pattern in north and south spheres. Horizontal deflation is grater near the poles, and less away from poles. The named is given after a French mathematician and physicist Gaspard-Gustave de Coriolis.The correct answer is D. Earth's rotation, which induces the Coriolis effect, creating distinct pressure zones like the Hadley and Ferrel cells in the atmosphere.
Earth's rotation is the primary cause of the two distinct pressure zones between the equator and the poles, known as the Hadley cell and the Ferrel cell. The rotation of Earth leads to the Coriolis effect, which deflects the movement of air and water in the atmosphere and oceans. This deflection causes air to circulate in a pattern of large convection cells, creating areas of high and low pressure.
At the equator, warm air rises due to the heating of the Earth's surface by the sun. As the Earth rotates, this air moves towards the poles and cools, sinking back towards the surface at around 30 degrees latitude, creating a high-pressure zone known as the subtropical high. This circulation pattern is part of the Hadley cell.
Further from the equator, between approximately 30 and 60 degrees latitude, the Coriolis effect and the movement of air from the poles create a zone of low pressure, known as the Ferrel cell. This cell is characterized by westerly winds and is situated between the Hadley and polar cells.
The troposphere interacting with the mesophere (A) does not directly cause distinct pressure zones. The ozone layer (B) is important for absorbing harmful UV radiation but does not create pressure zones. The fact that nitrogen is heavier than oxygen (C) is irrelevant to the creation of pressure zones, as both gases are well mixed throughout the atmosphere and do not separate based on weight due to the Earth's gravitational field."

An observer in canada sees a third quarter moon on a particular day. What will an observer in australia see on the same day?
Answer:
Australian observers will see a first quarter of moon on the same day.
Explanation:
This difference arises due to the fact the moon tends to be seen in complete reversal i.e upside downwards. The moon is in the same plane as that of the earth's equator. Moon tends to be flipped in the southern hemisphere and opposite in the northern hemisphere. Clockwise In the northern hemisphere, the moon in the southeast, the moon is from left to right. In the southern hemisphere, it's anticlockwise, east on right and west on left. Thus the face of the moon will be right to left. Also, there is a time gap between both the northern and southern countries.Fact: The Arctic latitudes are warming, which has released methane (a greenhouse gas) from thawing Arctic permafrost. This has increased the rate of warming in the Arctic. Systems analysis would label this as ________.
a) an open system
b) a closed system
c) a negative feedback loop
d) a positive feedback loop
e) an equilibrium condition
Answer:
C. A negative feedback loop.
Explanation:
As we know the melting of Arctic ice caps and polar regions due to global warming impact, and the release of methane a harmful natural gas in the environment from the Arctic system has created a negative impact upon the ecological system impacting badly and hence destroying it. The occurrence of a negative feedback is a way of earth saying that its resource cannot no longer bear the pressure and hence a balance needs to be made within this system, so system analysis predicts show this negative feedback as a disturbance being created.Both Ptolemy and Copernicus incorrectly explained the motions and orbital paths of the planets by basing their models on Greek ideologies of perfect form and motion. What were the Greek ideologies forperfect form and motion? -an oval and non-uniform motion - a circle and uniform motion
-an oval and uniform motion -a circle and non-uniform motion
Answer: a circle and uniform motion
Explanation:
Ptolemy's model of the universe placed the Earth motionless in the center of a universe subject to uniform circular motion, the other planets, the Moon and the Sun describe complicated orbits around it.
As Ptolemy was a respected astronomer and geographer, this idea was accepted for a long time, until Copernicus arrived with the new model (heliocentric theory) that placed the Sun at the center wir the Earth and other planets describing circular orbits around the star. However, the heliocentric theory did not explain why planets orbit the Sun at different speeds at different times, because this model used only circular orbits in uniform motion.
All of this is due to the Greek ideologies of perfect form and motion with a perfect circle. But then, the astronomer Johannes Kepler refined the Copernicus' heliocentric theory with the introduction of elliptical orbits.

a system of ethics that deals with morals and values in human conduct
Confucianism is best described as a system of ethics that deals with morals and values in human conduct. It prioritizes family, respect, virtue, and societal harmony
Explanation:Confucianism is best described as a system of ethics that deals with morals and values in human conduct. Although it's often likened to a religion, Confucianism is more of a philosophical and ethical framework that guides social interactions and societal duties. It was propagated by Confucius, an influential Chinese philosopher of the 5th century BC. Confucianism emphasizes the importance of family, respect for elders, cultivating virtue, and societal harmony. It is not primarily concerned with concepts such as reincarnation or achieving Nirvana, which are more related to religions like Hinduism and Buddhism.

An example of a positive feedback loop ________. A) are birds migrating south in response to colder temperaturesB) are predators eating most of their prey and then declining in numbersC) is a thermostat turning on the furnace as the temperature dropsD) is a pond becoming more acidic as a result of pollutionE) is melting arctic snow exposing dark surfaces that heat up and cause further melting
Answer:
D. Pond becoming more acidic to the pollution.
Explanation:
As the universe consists of two types of loops the positive and the negative feedback loop they are thus called the reinforcing and balancing types of loops in the ecological systems. Aggravates the system The positive loop or the feedback may be that the pond reaction to the chemicals thus becoming more of acidic as a result of pollution For example, the polar ice caps form a positive loop by the increase in greenhouse gases the melt is induced due to the spread effects and that is a universal phenomenon. In order to balance or bring a balance, the pond must become neutral or basic.Melting arctic snow exposing dark surfaces that heat up and cause further melting is an example of a positive feedback loop.
Explanation:An example of a positive feedback loop is melting arctic snow exposing dark surfaces that heat up and cause further melting. This is because as the snow melts and exposes dark surfaces, such as dirt or rock, the dark surfaces absorb more heat, causing the remaining snow to melt faster and expose even more dark surfaces, which then continues the cycle. This positive feedback loop can contribute to the rapid melting of arctic ice and the effects of climate change.

Describe what water regulation adaptations might have evolved in protists in hypertonic habitats such as great salt lake or in habitats with changing salt concentration.
Answer:
The hypertonic habitats is home to saline protists which depend on salts for their survival.
Explanation:
Protists are a multicellular organism like the algae, don't from natural groups have invertebrates. They freely occupy the environment that contains liquid water. As these microorganisms cant breath in freshwaters the need the salts to sustain themselves and responsible for the production of 30% of oxygen in the water sphere. Diatoms and other oozes are some of the most beautiful protists found to date, they are also home to corals and stick to the body of seafloors. As for long, they have adapted to the same type of conditions.New Zealand must desalinate seawater to have freshwater like Australia.
The statement is not true. In fact, the truth is the other way around. New Zaeland is a country that has an abundance of freshwater reserves, and considering that its population is relatively small, it has it very well in the water supply department. Australia, on the other hand, is a country very poor with freshwater sources, especially when its size its taken into consideration. Luckily for Australia it doesn't have very large population, so the problem is still not as big, though the country is gradually engaging into desalination of seawater, as in some areas there are too many people concentrated, and the water sources can not respond to the demand. New Zealand doesn't have this problem though, as the country has lot of streams, rivers, and lakes, most of which have high quality freshwater that can be used for drinking and everything else. The country needs to be careful though as the pollution is increasing, and even though it doesn't have a problem at the moment, if the current trend continues it might end up in a bad situation in several decades.

Which type of volcanism formed the Andes in South America?
production of mantle plumes
divergence between two continental plates
convergence between a continental plate and an oceanic plate
convergence between two continental plates
The convergence between a continental plate and an oceanic plate is subduction process where the denser oceanic plate force the thinner continental plate to sink into the mantle.
Answer: Option (D)
Explanation:
The type of volcanism formed the Andean Mountains in South America is due to subduction process. It is due to the converging of Nazca Plate over Antarctic Plate due to gravity and made them to sink below the South American Plate.
This process still continues today and due to the activity, it causes volcanic eruptions and earthquakes in that region. It was reported about 150 - 160 (approx.) active volcanoes in the Volcanic Belt of Andes.
