Mercator projection is designed to preserve angles and shapes, making it ideal for navigation. However, this comes at the cost of distorting area, particularly at high latitudes, where landmasses appear much larger than they actually are. This characteristic makes it less suitable for representing the true size of countries near the poles.

The Prime Meridian is the established zero-degree longitude line, which runs from the North Pole to the South Pole. It serves as the starting point for measuring longitude, allowing for the determination of east and west positions on the Earth's surface. This system is essential for navigation and mapping.

Savannas are characterized by a distinct wet and dry season, with grasslands being the dominant vegetation type. This climate zone supports a variety of wildlife and is typically found in regions near the equator, where rainfall patterns create a balance between lush growth during the wet season and dry, sparse conditions afterward.

The Ring of Fire is a horseshoe-shaped area in the Pacific Ocean basin characterized by high volcanic and seismic activity. It is home to numerous volcanoes and earthquakes due to tectonic plate movements, making it one of the most geologically active regions in the world. Thus, the statement is false.

A scale on a map can be expressed in various forms, including a ratio, bar scale, or verbal scale. A verbal scale uses words to describe the relationship between distance on the map and actual distance on the ground, making it easily understandable for users who may not be familiar with numerical ratios.

Mid-ocean ridges are underwater mountain ranges formed by the upwelling of magma at divergent tectonic plate boundaries. As tectonic plates move apart, new oceanic crust is created, making these ridges a prominent natural boundary that signifies the separation between two tectonic plates.

The Equator is an imaginary line that circles the Earth horizontally, equidistant from the North and South Poles. It effectively divides the planet into two equal halves, known as the Northern Hemisphere and the Southern Hemisphere, making the statement accurate.

Tundra is a cold, treeless region where the ground is permanently frozen, known as permafrost. This unique climate limits vegetation to low-growing plants such as mosses and lichens. The harsh conditions lead to sparse plant life, making the tundra distinct from other ecosystems like steppe or boreal forests.

Weathering refers to the natural processes that break down rocks into smaller particles through the actions of water, ice, and wind. These elements contribute to physical and chemical changes in the rock, leading to erosion and the gradual alteration of landscapes over time.

A rain shadow effect occurs when moist air rises over a mountain range, causing precipitation on the windward side. As the air descends on the leeward side, it loses moisture, resulting in decreased rainfall. This creates a drier climate in the area sheltered from the prevailing winds.

Latitude lines, also known as parallels, run horizontally around the Earth and measure the distance north or south of the equator. They are perpendicular to longitude lines, which run vertically from the North Pole to the South Pole. Therefore, the statement is false.

Asia is the largest continent, covering approximately 44.58 million square kilometers, making it the most extensive landmass. It is also home to over 4.7 billion people, which accounts for nearly 60% of the world's population, making it the most populous continent as well.
