6. Europe
7. Australia

Oceans:
1. Pacific Ocean
2. Atlantic Ocean
3. Indian Ocean
4. Southern Ocean (Antarctic Ocean)
5. Arctic Ocean
In simple words: The Earth has seven major landmasses called continents and five vast water bodies called oceans.

Exam Tip: Memorize the continents in order of size (largest to smallest) and remember that Australia is both a country and a continent.

II. Fill in the blanks

Question 1. An imaginary line that divides the earth into two equal halves is called ___________.
Answer: Equator
In simple words: The Equator is the zero-degree latitude line that splits the Earth into the Northern and Southern Hemispheres.

Exam Tip: Always capitalize Equator when referring to the primary line of latitude.

Question 2. The portion of the earth above the equator is called ___________.
Answer: Northern Hemisphere
In simple words: The half of the Earth that lies north of the Equator is the Northern Hemisphere.

Question 3. Lines of Longitude are also called as ___________.
Answer: Meridians
In simple words: Longitudes run from the North Pole to the South Pole and are known as meridians of longitude.

Exam Tip: Meridian comes from Latin roots meaning midday, as all points on the same meridian experience noon at the same time.

Question 4. There are ___________ number of latitudes drawn on the globe.
Answer: 181 (or 179 if excluding the poles)
In simple words: There are 90 latitudes in the Northern Hemisphere, 90 in the Southern Hemisphere, and the Equator itself, making 181 in total.

Exam Tip: Note that standard school textbooks generally accept 181 as the total number of latitude lines drawn at 1-degree intervals.

Question 5. The starting line to number the meridians is the ___________.
Answer: Prime Meridian
In simple words: The Prime Meridian, passing through Greenwich, London, is marked as \(0^\circ\) longitude and serves as the starting reference point.

Exam Tip: Do not confuse the Prime Meridian (\(0^\circ\) longitude) with the Equator (\(0^\circ\) latitude).

III. True or False.

Question 1. All the longitudes are of equal length.          ( True )
Answer: True
In simple words: Unlike latitudes which get smaller toward the poles, all meridian lines stretch from pole to pole and are equal in length.

Exam Tip: Longitudes form complete semi-circles of equal size.

Question 2. Lines of latitude are also called as meridians.          ( False )
Answer: False
In simple words: Lines of latitude are called parallels, while longitudes are called meridians.

Exam Tip: Read carefully - meridians are longitudes, parallels are latitudes.

Question 3. The north pole is marked as 90 S.          ( False )
Answer: False
In simple words: The North Pole is located in the Northern Hemisphere and is marked as \(90^\circ\text{N}\).

Exam Tip: South Pole is \(90^\circ\text{S}\); North Pole is \(90^\circ\text{N}\).

Question 4. Equator is taken as the starting line to number the parallels.          ( True )
Answer: True
In simple words: The Equator is designated as \(0^\circ\) latitude, from which all other parallel lines are numbered north and south.

Exam Tip: Equator is the reference baseline for latitude measurement.

Question 5. All Parallels are equal in length.          ( False )
Answer: False
In simple words: Parallels decrease in length as you move away from the Equator toward the poles, where they become points.

Exam Tip: The Equator is the longest parallel circle.

IV. Give reason.

Question 1. The shape of the earth is like an orange.
Answer: The Earth is not a true sphere; it bulges slightly at the Equator and is slightly flattened at the North and South poles, which gives it a shape very similar to an orange (or an oblate spheroid).
In simple words: The Earth bulges in the middle and is flat at the top and bottom due to its rotation.

Exam Tip: Use the scientific term 'oblate spheroid' in your answer for full marks.

Question 2. The parallels are not equal in length.
Answer: Because the Earth curves inward and narrows as it extends from the wide equatorial region toward the northern and southern poles, the circles of latitude drawn around it become progressively smaller in circumference.
In simple words: Parallels near the poles circle a smaller diameter of the Earth than the Equator.

Exam Tip: Remember that latitude circles shrink from maximum length at the Equator to zero at the poles.

V. Choose the correct option.

Question 1. Total number of longitudes drawn on the globe
a) 180
b) 340
c) 360
Answer: (c) 360
In simple words: There are 360 degrees in a circle, so 360 longitude lines are drawn at 1-degree intervals around the globe.

Exam Tip: Longitudes measure complete circular degrees around the Earth's axis (\(360^\circ\)).

Question 2. The longest 0 latitude is
a) Equator
b) Prime meridian
c) north pole
Answer: (a) Equator
In simple words: The Equator is the \(0^\circ\) latitude line and represents the widest circumference of the Earth.

Question 3. At \(23\frac{1}{2}^\circ\text{S}\) lies the
a) Tropic of cancer
b) Arctic circle
c) Tropic of Capricorn
Answer: (c) Tropic of Capricorn
In simple words: The Tropic of Capricorn is located in the Southern Hemisphere at \(23\frac{1}{2}^\circ\text{S}\).

Exam Tip: Cancer is North (\(23\frac{1}{2}^\circ\text{N}\)), Capricorn is South (\(23\frac{1}{2}^\circ\text{S}\)).

Question 4. At \(66\frac{1}{2}^\circ\text{N}\) lies the
a) South pole
b) Arctic circle
c) Antarctic circle
Answer: (b) Arctic circle
In simple words: The Arctic Circle is situated in the Northern Hemisphere at \(66\frac{1}{2}^\circ\text{N}\).

Exam Tip: Arctic is North, Antarctic is South.

VI. Using the atlas, Find the latitudes and longitudes between which Saudi Arabia and India lies.
Answer:

In simple words: Atlas coordinates help pinpoint the exact geographical boundaries of countries on Earth.

Exam Tip: Always include direction letters (\(\text{N}, \text{S}, \text{E}, \text{W}\)) when writing geographic coordinates.

VII. Using the atlas, Name the states in India through which Tropic of Cancer passes.
Answer: The Tropic of Cancer (\(23\frac{1}{2}^\circ\text{N}\) latitude) passes through 8 states in India:
1. Gujarat
2. Rajasthan
3. Madhya Pradesh
4. Chhattisgarh
5. Jharkhand
6. West Bengal
7. Tripura
8. Mizoram
In simple words: An imaginary line divides India almost into two equal halves from west to east across these eight states.

Exam Tip: Remember the mnemonic or sequence from west to east (Gujarat to Mizoram) to easily recall all 8 states.
