Describe Earth Feature Patterns - 4th Grade Science

What does a closed loop of contour lines with lower values toward the center show?

A depression or basin. Elevation decreases toward the center, forming a low area.
What is the contour interval on a topographic map?

The elevation difference between neighboring contour lines. Usually consistent across the map (e.g., every 10 or 20 feet).
What is the definition of elevation on a map?

Height of land above sea level. Measured in feet or meters from sea level as the reference point.
What do widely spaced contour lines on a topographic map indicate?

A gentle slope or flatter land. Lines spread apart when elevation changes gradually over longer distances.
Which option best describes a plain on a physical map: A) low, flat area B) steep, narrow valley?

A) Low, flat area. Plains have minimal elevation change across large areas.
What does the compass rose on a map show?

The directions (north, south, east, and west). Essential for orientation and understanding which way features are positioned.
Which option best describes a plain pattern on a physical map?

A broad area of mostly flat or gently rolling land. Shows minimal elevation change over large areas.
What does the compass rose on a map show?

Directions (north, south, east, west). Usually points north and helps orient the map properly.
What is a topographic map?

A map that shows land shape and elevation using contour lines. Contour lines connect points at the same height above sea level.
Choose the best conclusion if a map shows earthquakes clustered in narrow belts across Earth.

Earthquakes often occur along tectonic plate boundaries. Plate boundaries are zones of seismic activity forming linear patterns.
Which map data layer most directly helps you identify mountain ranges and plains?

To identify and describe patterns in Earth features and landforms. Maps reveal repeating features and landform distributions across Earth's surface.

A ridge. Forms a long, narrow elevated area between valleys.

U-shaped valleys. Glaciers carve wider, rounder valleys than rivers' V-shapes.
Identify the map tool that explains what symbols, colors, and lines mean.

Legend (key). This key decodes all map symbols for proper interpretation.
Which map feature helps you locate the exact position of a place using lines?

A grid system (latitude and longitude or map grid). These intersecting lines create coordinates for precise location finding.
What landform is indicated where contour lines form a V shape that points downhill?

A ridge or spur. Ridges extend outward from peaks, creating V shapes pointing downslope.
Which option best describes a delta pattern where a river meets an ocean or lake?
