KVS LDCE Geography Question Paper and Answers pdf 2023

4. Diagonal scale

Topographical maps usually provide a statement scale, representative fraction (RF), and graphical scale to represent distances and relationships accurately. Diagonal scales are typically used for more specialized engineering or architectural purposes.

4. 00.0° latitude

The 00.0° latitude, also known as the Equator, is a great circle.

3. 15°

The Sun traverses 15° of longitude in one hour due to the Earth’s rotation. This is because the Earth completes a 360° rotation in 24 hours (360° / 24 hours = 15° per hour).

3. Approximately 111.3 km

This value is derived from the Earth’s circumference, which is about 40,075 km, divided by 360 degrees of longitude (40,075 km / 360 = 111.3 km per degree).

2. Divisible by 7.5

Each time zone generally covers 15 degrees of longitude, and the standard meridian is usually centered in the time zone, which makes it a multiple of 7.5 degrees (e.g., 0°, 7.5°, 15°, 22.5°, etc.).

1 Mereator Projection

The Mercator projection is most appropriate for navigation at sea routes. It preserves angles and shapes of small objects, making it useful for maritime navigation because it allows sailors to plot straight-line courses (rhumb lines) easily.

1. 15’×15’ map

The smaller the area covered by the map, the more detailed and precise the information it can display.

4. Waterfall

In waterfall the elevation changes abruptly over a very short horizontal distance, resulting in the contours being drawn very close together or even merging.

2. Horizontal photographs

The correct answer is a Horizontal photograph. There are several types of aerial photography. These are as follows:

1. Vertical Aerial Photography: In vertical aerial photography, the camera axis is perfectly vertical—meaning it points directly down at the ground.
2. Low Oblique Aerial Photography: The camera axis is tilted more than 3 degrees, but the horizon is not visible in the image.
3. High Oblique Aerial Photography: Tilting the camera axis approximately 60 degrees. The resulting images cover a larger area, and the horizon is visible.
4. Combined aerial photography: Combines vertical and oblique images. 
5. Orthophotomap: It’s like a “true” map, with consistent scale and accurate measurements.
6. Leaf-Off/Leaf-On Aerial Photography: Leaf-off photos are taken during winter when trees have shed their leaves. Leaf-on photos are captured during the growing season when foliage is abundant.
7. Horizontal Aerial Photography: The camera axis will not touch the ground plane, and consists of two or more drone images captured in a single row. 

3. Violet

In the electromagnetic spectrum, the wavelength of violet light ranges from about 380 to 450 nanometers, which is shortest.

1. North

This orientation helps to minimize direct sunlight entering the screen when it is opened, ensuring that the temperature and humidity measurements inside are not affected by the sun’s heat.

3. Post-Modernism

Post-Modernism is the latest approach among the ones listed in human geography. This approach emerged in the late 20th century and focuses on understanding the complexities and diversities of human experiences.

4. Births − deaths + in migration − out migration

This formula accounts for natural increase (births minus deaths) and net migration (in migration minus out migration) to determine the total change in population.

2. Information and computer

Advances in this field, particularly in the last few decades, have revolutionized how we communicate, process information, and perform various tasks, marking significant technological progress compared to earlier developments.

3. Basic Needs Approach

This approach focuses on ensuring that all individuals have access to basic necessities such as food, water, shelter, education, and healthcare, aiming to improve the quality of life and overall well-being of people.

2. Quinary workers

These individuals are at the highest level of decision-making and include top executives, government officials, and other high-level managers who possess specialized knowledge and skills.

1. Milpa

This traditional method involves cutting down and burning vegetation to create fields for cultivation.

4. Vegetables farming

This type of farming involves growing vegetables on a large scale and transporting them to markets, often using trucks.

2. Near to raw material

This is because sugarcane, the primary raw material for sugar production, is bulky and perishable, so processing it close to the source minimizes transportation costs and ensures the cane is processed while still fresh.

1. Policy formulators

Quinary activities are high-level decision-making roles and include activities such as policy formulation, which involves creating and implementing policies at the highest levels of government and corporate sectors.
