A series of lines drawn on a map is called a grid. A grid is a network of horizontal and vertical lines that intersect and form squares or rectangles on a map. This grid system is used to identify and locate specific points or areas on a map by using coordinates or grid references. It helps in accurately measuring distances, determining directions, and providing a reference system for navigation and analysis on a map.

The Prime Meridian is the line of longitude that divides the Earth into Eastern and Western Hemispheres. It is considered the starting point for measuring longitude and is defined as 0 degrees. This definition aligns perfectly with the given term "0 degree line of longitude," making Prime Meridian the correct answer. A thematic map is a visual representation of a specific theme or topic, topography refers to the physical features of an area, and a dike is a barrier used to control or redirect water flow, none of which relate to the given term.

A Geographic Information System (GIS) is a software management tool that allows for the collection, storage, analysis, and presentation of spatial data. It enables users to visualize and understand geographic patterns and relationships through the use of maps, data layers, and various analytical tools. This aligns with the definition of "software management of spatial information" as it involves the use of software to manage and manipulate geographic data. Map Projection, Flow Lines, and Grid References are not specifically related to the software management aspect of spatial information.

A polar projection is a type of map projection that shows the Earth's polar regions in detail. It is designed to accurately represent the shape and size of the polar regions, which are often distorted in other types of map projections. This term specifically refers to a map projection that focuses on one hemisphere, meaning it covers only half of the Earth's surface. Therefore, "covers the polar regions of a selected hemisphere" is the best definition for a polar projection.

Sudan is the correct answer because it is the smallest country in total area among the given options. Argentina is the second largest country in South America, Brazil is the largest country in South America and the fifth largest in the world, and Canada is the second largest country in the world. Therefore, Sudan is the smallest country among the options provided.

Seychelles is the correct answer because it is the smallest country in terms of total area. While Sri Lanka, Burma, and Peru are all larger countries, Seychelles has the smallest land area among these options.

Tokelau is the correct answer because it is the smallest country in terms of total area. Tokelau is a dependent territory of New Zealand and consists of three coral atolls in the South Pacific Ocean. It has a total land area of only 10 square kilometers, making it the smallest country in the world. Spain, Bulgaria, and the United Kingdom are all larger in terms of total area compared to Tokelau.

Yemen is the correct answer because it is the smallest country in total area among the given options. Although Australia is the smallest continent, it is not the smallest country. Mozambique and Algeria are both larger in total area compared to Yemen. Therefore, Yemen is the smallest country in terms of total area.

Tanzania is the correct answer because it is the smallest country in total area among the given options. While Argentina, Algeria, and Sudan are all larger countries, Tanzania has a smaller land area compared to them.

The term "Statement Scale" refers to a map scale that is expressed using both words and numbers. This means that the scale is described using written statements as well as numerical ratios. It provides a clear indication of the relationship between distances on the map and the corresponding distances in real life. This type of scale is commonly used in cartography to ensure accurate representation and measurement on maps.

The term "bearing" refers to the angular compass direction expressed in degrees. It is commonly used in geography and navigation to indicate the direction of one point relative to another. This term is often used when describing the direction of a landmark or the orientation of a map.

A system is a collection of things that forms a whole. It consists of interconnected and interdependent parts that work together to achieve a common goal or function. In this context, a system refers to a complex arrangement or organization of components that interact and function together as a unified whole.

An isotherm is a line on a map that connects points of equal temperature. It is commonly used in geography to represent temperature distribution across a specific area. Thematic maps are general-purpose maps that can represent various themes, such as population density or land use. While ocean and land-use maps are related to geography, they do not specifically represent the concept of joining points of equal temperature like an isotherm does. Therefore, the term "isotherm" is the best fit for the given definition.

Vanuatu is the correct answer because it is the smallest country in total area among the given options. Guinea-Bissau, Belarus, and Sierra Leone are all larger in terms of total area compared to Vanuatu.

A thematic map is a type of map that displays specific information or data about a particular topic or theme. It is designed to show patterns, trends, or distributions of a specific attribute or phenomenon across a geographic area. Unlike other options, such as degree, trend line, or map projection, a thematic map focuses on a specific topic or theme rather than general geographic features. Therefore, the correct answer is thematic map.
