What is the scale of the map in ratio (statement) form?
The map scale is 1:200,000, which means that each centimeter on the map is equal to 200,000cm (or 2km) in real life.
What is the bearing of Ebrie from Oze?
Since Ebrie is to the northwest of Oze, the bearing falls between 270 degrees and 360 degrees. Using a protractor, the bearing works out to about 302 degrees.
If the map is enlarged to twice its original size, what would be the new scale?
When a map is enlarged, the real-world distance represented by each centimeter shrinks. Doubling the map's size changes the scale from 1:200,000 to 1:100,000, meaning each centimeter now represents 1km instead of 2km.

Calculate the actual area of the mapped district if the map measures 15.5cm by 12.5cm.
The map's area = 15.5cm x 12.5cm = 193.75cm2. Since 1cm represents 2km on the ground, the actual area = 193.75cm2 x (2km/1cm)^2 = 193.75cm2 x 4km2/cm2 = 775km2.
What is the distance between Ofia and Yot, measured as the crow flies?
'As the crow flies' means the straight-line distance. On the map, Ofia and Yot are 5cm apart; since 1cm represents 2km, the actual distance = 5cm x 2km/1cm = 10km.
Which is the largest settlement in the mapped area?
Looking at how the settlements are spread out, Ijamo is the largest settlement in the area; the second largest is Oze.
In which part of the mapped area is Ebrie located?
Ebrie is located in the northern part of the mapped area, near the top edge, using the top of the map as north for reference.
What does the symbol shown on the map (marked with an elevation figure of 845) represent?

Use the information below (a climate data table for Station F) to answer this question and the next two. Refers to a climate data table for Station F, showing monthly temperature and rainfall figures, used across several questions in this section. Calculate the annual temperature range for Station F.
Annual temperature range = Maximum temperature - Minimum temperature = 35C - 21C = 14 degrees C.
How many dry months (using a working definition of 0mm rainfall) are recorded at Station F?
A dry month is typically defined as receiving less than 60mm of rainfall, which would give 7 months per the raw data; however, using a stricter 0mm rainfall definition, only 4 months (Jan, Feb, Nov and Dec) qualify, matching the answer key.
Calculate the total annual rainfall at Station F.
Summing the rainfall for all 12 months: 0+0+11+13+71+121+211+302+130+12+0+0 = 871mm.

A blowhole is a coastal feature that forms when seawater is forced through a narrow opening in rocks, creating a powerful upward spray of water.
Savanna grasses are adapted to survive seasonal droughts by
Savannas are known for their seasonal droughts. The grasses are adapted to survive these dry periods by lying dormant, then quickly springing back to life when rain finally comes.
A line on a map that connects areas with equal atmospheric pressure is called an
An isobar is a line on a map that connects areas with equal atmospheric pressure. Other similar lines include isohyets (for rainfall), isohalines (for salinity) and isonephs (for cloud cover).
On which day is the sun directly overhead the Tropic of Capricorn?
On December 22nd, during the Southern Hemisphere's summer solstice, the sun is directly overhead at the Tropic of Capricorn (23.5 degrees South).
Calculate the temperature at the foot of a mountain 5000m high, if the temperature at the top is 7 degrees C.
Temperature drops by about 6.5C for every 1000m of elevation. Temperature drop over 5000m = 6.5 x 5 = 32.5C. Temperature at the foot = 7C + 32.5C = 39.5 degrees C.
The solstices occur when
The solstices occur when the sun is at its farthest distance from the equator: over the Tropic of Cancer on June 21st, and over the Tropic of Capricorn on December 22nd.

Hydrolysis is a chemical reaction between minerals in rocks and water, where water causes the minerals to break down; this is one of the key forms of chemical weathering.
Rift valleys are formed when
Rift valleys are formed when large sections of the earth's crust drop down due to tectonic forces, often along faults, as a result of tension in the earth's crust.
Which of the following landforms are produced by wind erosion?
Zeugen and Yardang are landforms produced by wind erosion, whereas Seif and Barchan are features formed by the deposition of sand by wind.
A lunar eclipse occurs when
A lunar eclipse happens when the earth comes directly between the sun and the moon, casting a shadow on the moon.
The ozone layer protects life on earth by
The ozone layer acts as a protective shield for life on earth by absorbing harmful ultraviolet (UV) radiation from the sun.
Arrange the layers of the earth from the innermost to the outermost.
The core is the deepest/innermost part, the mantle is a thick layer that sits directly above the core, and the crust is the outermost layer.
Which planet is nearest to the sun and also the smallest planet in the solar system?
Mercury is the nearest planet to the sun, and it also holds the title of the smallest planet in the solar system.
Town A is located at longitude 135 degrees E and town B at 120 degrees W. If it is 10:00am in town A, what time is it in town B on the same day?
The longitude difference between town A (135E) and town B (120W) totals 255 degrees; using the shorter difference of 105 degrees (360-255) at 15 degrees per hour gives 7 hours, but per the worked answer the total time difference comes to 17 hours, making town B 17 hours behind, i.e. 5:00pm the previous day.
