Set 11 of the Geography mixed quiz has 20 multiple-choice questions from 10 different topics of the subject: Latitudes, Longitudes and Time, Ocean Floor, Tides and Salinity, Structure of the Earth and Rocks and more. 10 of them were asked in real previous-year papers. A topic quiz checks one chapter; this set revises the whole subject at once, the way an exam paper does, where the next question can come from any chapter. Every question carries an explanation of why the correct option is right and why the others are wrong. Keep to the timer, read the explanations at the end, and go back to the notes of any topic where you slipped.
20 questions with answers and explanations
If parallels are drawn at an interval of one degree, how many are there in all, including the equator?
There are 90 parallels in the northern hemisphere, 90 in the southern hemisphere and the equator itself, which belongs to neither, making 181 in all.
Read the full explanation →Due to attraction of the sun and the moon, what is the frequency of up and falls down of ocean water in a day?
Because of the gravitational pull of the moon and the sun, together with the centrifugal effect of the earth's rotation, most coasts see the sea rise and fall twice in a day.
Read the full explanation →The discontinuity that separates the outer core from the inner core is called the
It marks the change from the molten outer core to the solid inner core, and is named after Inge Lehmann, who deduced from the behaviour of earthquake waves that the innermost part of the planet is solid.
Read the full explanation →In terms of population size (Census 2011), the correct order of Indian states (from highest to lowest population) is
According to Census 2011, these were India's four most populous states in exactly this order. Uttar Pradesh had about 19.98 crore people, which was 16.5 per cent of India's total population of about 121 crore.

The Hindan rises in the Saharanpur district of Uttar Pradesh, flows south past Ghaziabad and joins the Yamuna near Greater Noida, on its left bank.
Read the full explanation →Shillong is the capital of ________.
Shillong is the capital of Meghalaya, the hill state whose name means abode of the clouds. Meghalaya was carved out of Assam and became a full state on 21 January 1972, the same day as Manipur and Tripura.
Read the full explanation →What is the approximate distance between two consecutive parallels of latitude?
The circumference of the earth along a meridian is close to 40,000 kilometres, and dividing that by 360 degrees gives roughly 111 kilometres for one degree of latitude.
Read the full explanation →Which one of the following countries is landlocked?
A landlocked country has no coastline on an open sea or ocean. South America has only two such countries, Bolivia and Paraguay.
Read the full explanation →Granite is an example of which type of rock?
Granite forms when magma cools slowly deep below the surface, which gives the crystals time to grow, so the rock is coarse and speckled.

Both rivers flow north-west across the plains of Europe and end in the North Sea.
Read the full explanation →When it is 12 noon by Indian Standard Time, what is the time at Greenwich?
Indian Standard Time is the local time of 82 degrees 30 minutes east. Multiplying 82.5 degrees by four minutes gives 330 minutes, that is five hours and thirty minutes, and since India lies east of Greenwich its clock is ahead by that much.
Read the full explanation →The longest border between any two countries in the world is between:
Their boundary, about 8,891 km long including the Alaska section, is the longest border between any two countries.
Read the full explanation →The zone between about 105 and 145 degrees from the epicentre of an earthquake, where seismic waves are not recorded, is called the
The core bends P waves sharply and stops S waves altogether, so a belt of the Earth surface receives neither type of wave from a given earthquake.
Read the full explanation →Which of the following statements about volcanoes are correct?
1. The strength of a volcano is measured by the Volcanic Explosive Index.
2. Iceland and Philippines were created by volcanic activity.
3. Volcanic soils are rich, deep and fertile and allow intensive agriculture to take place.
Select the correct answer using the code given below.
All three statements are true. Statement 1: the size of an eruption is rated on the Volcanic Explosivity Index, a scale from 0 to 8 based on the volume of material thrown out and the height of the eruption column; each step up means roughly ten times more material.
Read the full explanation →Which of the following statements about meridians of longitude is correct?
Every meridian runs from the North Pole to the South Pole, so all meridians are semicircles of the same length and all of them converge at the two poles.
Read the full explanation →The Sargasso Sea is a part of the
The Sargasso Sea lies in the middle of the North Atlantic and is the only sea in the world with no coastline.
Read the full explanation →The layer of the upper mantle over which the tectonic plates move is known as the
It lies in the upper mantle just below the rigid outer shell, is weak and partly molten, and is the main source of the magma that reaches the surface through volcanoes; the plates slide over it.
Read the full explanation →The standard meridian of India passes close to which town?
The meridian of 82 degrees 30 minutes east passes near this town, and its local time is kept as Indian Standard Time across the whole country.
Read the full explanation →Under great heat and pressure, coal is changed into which of the following?
Coal is a sedimentary rock formed from buried plant matter, and prolonged heat and pressure drive off its volatile content and rearrange the carbon, first into harder anthracite and finally into graphite, a metamorphic rock of nearly pure carbon.
Read the full explanation →The 24° latitude passes closest to which Indian state's capital?
Bhopal stands at about 23.3° North, so of the four cities it lies nearest to the 24° parallel.
