Answer 1

Answer:

C.

Explanation:

Answer 2
Answer:

Geothermal renewable energy has declined in recent years.

Explanation:

Geothermal energy is generated by the high temperatures within the earth's core. Though it has been used as an energy source for a long time, it has declined in recent years due to the increase of other use of renewable and non-renewable energy.

The efficiency of geothermal energy supply is also not reliable and there are cost implications to think about. The geothermal reserve in most location is in places that are far from people, therefore, transportation costs become high. There are also pumping costs, high electricity cost per megawatt, etc.

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

Answers

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.

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.

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

Answers

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.

An observer in canada sees a third quarter moon on a particular day. What will an observer in australia see on the same day?

Answers

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.

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 .

Answers

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."

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?

Answers

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.

Answers

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.
Final answer:

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.

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?

Answers

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.

New Zealand must desalinate seawater to have freshwater like Australia.

Answers

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.
