Observing The Earth System Mataya Topil January 15, 2024
Abstract- This lab explores datasets that represent different spheres of the Earth system to gain a better understanding of Earth system science. The visualizations include Earth history graphs, paleogeography maps, Earth’s dynamo, the thickness of the crust, annual precipitation distribution map, global heat flow, strength of the magnetic field, and biological productivity. The objective is to see the hypotheses for component interactions and analyze patterns in the data. Introduction and Purpose-
This lab explores datasets from various earth system spheres, aiming to understand Earth system science. The focus is on seeking hypotheses for component interaction through the analysis of visualization, including maps, satellite imagery, graphs, and technical drawings. Learning objectives involve explaining the earth systems concept describing Earth history information and using graphical data to formulate and test hypotheses. Equipment Used- -
Maps
-Satellite imagery -Visualizations provided in the document
Hypothesis-
If the Earth’s crust is thinner, then heat transfer will be more efficient conversely; if the crust is thicker, heat transfer will be less efficient.
Procedure- 1.
Review various visualizations representing Earth system features. 2.
Concentrate on recognizing patterns, changes, edges, gradients, or slopes in the graphs or maps. 3.
Choose two visualizations and investigate potential relationships. 4.
Describe chosen visualizations in detail and in isolation. 5.
State hypotheses about connections between chosen visualizations. Data and Analysis- I chose to look at the crustal thickness and the heat flow maps
. The heat low was a map that has different colors that changed based on the area. The map
uses color gradient where different colors represent varying levels of heat flow. Warmer colors like red and orange are used to indicate higher heat flow, and cooler colors like blue and green represent lower heat flow. A heat flow map is a map that can be used to understand the areas that have a high heat transfer.

The crustal thickness map is a map that has different areas that are different colors based off the earth’s crust thickness. This map has a color gradient that is used to represent different crustal thickness values, the warmer colors may indicate a thicker crust, which the cooler colors indicate a thinner crust. There are also contour lines, with connect points with equal crustal thickness values. These lines help to visualize the crustal thickness across the map. These maps can be used to people study tectonic plates, as well as volcanic and seismic activity. One pattern that was noticed was the relationship between crust thickness, and heat transfer. When there was a thicker crust, the color indicating the heat flow was lighter or shades of blue. This goes the other way as well, when there is a thinner crust, then the color indicating the heat flow as darker, or shades of red. If the Earth’s crust is thinner, then heat transfer will be more efficient conversely; if the crust is thicker, heat transfer will be less efficient. These patterns
are important because areas with thinner crust may have greater accessibility to geothermal heat, making them attractive for geothermal energy extraction and thicker crust may impede the upward movement of magma, while thinner crust facilitates the ascent of magma, potentially leading to increased volcanic activity in those regions.
Answer to Questions- (No Questions for this lab)
Conclusion- In conclusion, this lab delved into diverse datasets representing various spheres of the Earth system, employing visualizations such as maps, satellite imagery, and graphs. The objective was to understand Earth system science by formulating hypotheses for component interactions and analyzing patterns in the data. Through the examination of crustal thickness and heat flow maps, a noteworthy pattern emerged. The relationship between crust thickness and heat
transfer was observed, revealing that areas with thicker crust exhibited lighter colors on the heat flow map (indicating less efficient heat transfer), whereas areas with thinner crust displayed darker colors (indicating more efficient heat transfer).
