Earth Science Quiz: 6th Grade Trivia Questions!

Explanation
A choropleth map uses color shading to represent different values or categories of data for specific geographic areas. This type of map is commonly used to visualize data such as population density, income levels, or election results. By assigning different colors to different ranges or categories, it allows for easy interpretation and comparison of data across different regions.

Explanation
A line of best fit is a straight line that represents the general trend or relationship between the data points on a scatter graph. It is used to estimate and predict values within the data set. The line is positioned so that it minimizes the overall distance between the line and the data points. This line helps to visualize the overall pattern or trend in the data and is commonly used in statistical analysis and forecasting.

Explanation
A vertical bar graph can be used to show data that adds up to 100%. In a vertical bar graph, the height of each bar represents the value of a specific category or variable. The total height of all the bars combined can be 100%. Therefore, a vertical bar graph can effectively display data that adds up to 100%.

Explanation
Contour lines on an O.S. map are typically represented in brown color. This color is used to indicate the elevation and shape of the land. Each contour line represents a constant elevation, and by studying the pattern and spacing of these lines, one can understand the topography of the area. Brown is commonly used because it provides a clear contrast against the other map features and is easily distinguishable.

Explanation
A line from east-west on an atlas map is a line of latitude. Latitude is a geographic coordinate that measures the distance north or south of the equator. It is represented by horizontal lines on a map or globe, running parallel to the equator. These lines help in determining the location and climate of a place. Longitude, on the other hand, refers to the vertical lines on a map that measure the distance east or west of the prime meridian. Meridian is a term used to describe a line of longitude, while reference is a general term that does not specifically relate to east-west lines on a map.

Explanation
A line graph is best for showing continuous data because it displays the relationship between two continuous variables over a continuous interval. It is useful for tracking trends and changes over time, as it connects data points with lines, allowing for a smooth representation of the data. Pictographs, pie graphs, and vertical bar graphs are more suitable for representing categorical or discrete data.

Explanation
To give a 6 figure grid reference, we imagine the map square is divided into 10 equal parts or 10ths. This means that each side of the square is divided into 10 smaller sections, allowing for a more precise location pinpointing on the map.

Explanation
The correct answer is "Ordnance Survey." Ordnance Survey is a well-known mapping agency in the United Kingdom that produces highly detailed and accurate maps. Their maps are commonly referred to as O.S. maps.

Explanation
A map often includes an arrow pointing north because north is considered the reference direction on most maps. This arrow, known as a compass rose, helps orient the map and allows users to understand the direction in which they are looking at the map. By indicating north, the arrow provides a sense of direction and helps users navigate and understand the layout of the map more easily.

Explanation
The set of ranges 0-3, 3-10, 10-11 is best for a choropleth map key because it provides a clear and balanced distribution of values. The first range covers the lowest values (0-3), the second range covers a wider range of values (3-10), and the third range covers a specific and narrow range of values (10-11). This allows for a more accurate representation of the data and makes it easier for the viewer to interpret the map.
