October 26th Static Quiz Geography Origin and Evolution Part 2

Ans;- b) Origin of universe- The Big Bang theory

Explanation;-

Statement a and c are reversed.

In 1950, Otto Schmidt and Carl Weizascar gave the ‘nebular hypothesis’, that the sun was surrounded by solar nebula containing mostly the hydrogen and helium along with what may be termed as dust.

The friction and collision of particles led to formation of a disk-shaped cloud and the planets were formed through the process of accretion.

The most popular argument regarding the origin of the universe is the Big Bang Theory. It is also called expanding universe hypothesis.

Edwin Hubble, in 1920, provided evidence that the universe is expanding.

It is generally believed that the formation of moon, as a satellite of the earth, is an outcome of ‘giant impact’ or what is described as “the big splat”.

Ans:- d) All of the above
Explanation:-
The present composition of earth’s atmosphere is chiefly contributed by nitrogen and oxygen.
The first stage is marked by the loss of primordial atmosphere. In the second stage, the hot interior of the earth contributed to the evolution of the atmosphere. Finally, the composition of the atmosphere was modified by the living world through the process of photosynthesis.
The early atmosphere, with hydrogen and helium, is supposed to have been stripped off as a result of the solar winds. During the cooling of the earth, gases and water vapour were released from the interior solid earth. The process through which the gases were outpoured from the interior is called degassing.
Continuous volcanic eruptions contributed water vapour and gases to the atmosphere.

Ans:- b) Planets between the sun and the belt of asteroids.
Explanation:-
Our Solar system consists of eight planets.
Our solar system consists of the sun (the star), 8 planets, 63 moons, millions of smaller bodies like asteroids and comets and huge quantity of dust-grains and gases.
Out of the eight planets, Mercury, Venus, Earth and Mars are called as the inner planets as they lie between the sun and the belt of asteroids the other four planets are called the outer planets.
Alternatively, the first four are called Terrestrial, meaning earth-like as they are made up of rock and metals, and have relatively high densities. The rest four are called Jovian or Gas Giant planets. Jovian means Jupiter-like.

Ans;- b) Every country has only one Standard Meridian Time.
Explanation:-
As question asked to choose not correct , statement b is not correct
The number of time zones a country practices mostly depends on the size of the country .
For example, it’s impossible for a country as huge as Russia with the area of 17.1 million km² to process on only one time zone –this might create a problem of day-night difference within the same country .
So Russia has 11 time zones and USA has 6 time zones.
However there are certain exceptions like china which works on only one time zone despite its size.
Indian Standard Time is calculated on the basis of 82.58° E longitude and its uniform all around the country.

Ans:- d) All of the above
Explanation:-
The International Date Line is an imaginary line of longitude on the Earth’s surface located at about 180 degrees east (or west) of the Greenwich Meridian and marks the divide where the date changes by one day.
It makes some deviations from the 180-degree meridian to avoid dividing countries in two, especially in the Polynesia region.
The time difference between either sides of the International Date Line is not always exactly 24 hours because of local time zone variations.
If you travel around the world, changing standard time by one hour each time you enter a new time zone, then a complete circuit would mean that you adjusted your clock or watch time by 24 hours.
This would lead to a difference of one day between the date on your clock and the real calendar date.
To avoid this, countries are on either side of the International Date Line which runs down the middle of the Pacific Ocean. If you cross the date line moving east, you subtract a day, whereas if you are moving west you add a day.

Ans;- b) Bering Strait

Explanation;-

Bering Strait is nearest to the International Date line, because the international Date line runs equidistant between the American continents, on its East and Asia, Australia, and Europe on its west.

Ans:- a) 5:30 P.M
Explanation:-
As we know Earth rotates 360 ° in 24 hours,
Per hour earth will cover (360/24 ) 15°degrees.
Therefore,
15 degree= 1 hour and
1 degree = 4 minutes

Now according to the given problem , we know while moving east from Greenwich the time increases .
So difference between GMT and IST(82.5 degree)= 82.5-0 is 82.5 degrees
And 1 degree =1/15 hours
So 82.5 degree= 1/15 X 82.5=5.5
That is 5 and a half hour ahead
So, 5:30 P.M

Ans:- b) Earth’s revolution around the sun in an elliptical manner
Explanations;-
The earth’s revolution in the inclined position in the elliptical orbit leads to variation in the length of day and nights all over the globe.
As the earth axis makes an angle of 66 1/2 degrees with the plane of elliptic, during the month of June when it is summer over the northern hemisphere, the sun rays directly fall on the tropic of cancer.
So this leads to longer days and shorter nights in the northern hemisphere area leading to increase in the day light as well. Length of day and night does vary according to the season and latitudinal position. At the equator the day and night are mostly of same lengths all round the year.

Ans:- c) Both 1 and 2
Explanation:-
Both the statements are reversed
Latitude of a place is measured as the angular distance of the place from the equator. All latitudes also called as parallels are concentric circles.
Equator is the largest latitude of earth dividing the earth in two equal halves.
Longitude of a place is measured as the angular distance of the place from the prime meridian .
Longitudes also known as meridians play a significant role in measuring the time zone of an area. 0 degree longitude is Greenwich in UK and 180 degree is the International Date Line.

Ans;- d) 1, 2, 3, 4, 5 and 6

Explanation;-
