Question

According to the diagram provided, how much has sea level changed since the last glacial maximum?

Answer 1

Sea level has risen by approximately 120 meters since the last glacial maximum 20,000 years ago, with an accelerated rise of 3.6 mm per year observed since 1993.

Step-by-step explanation:

Since the last glacial maximum approximately 20,000 years ago, sea level has risen by about 120 meters.

This significant change is attributed to the melting of glaciers and ice sheets due to global warming, along with the thermal expansion of sea water.

Recent measurements indicate an average sea level rise of 3.6 mm per year since 1993. Looking at historical data, in the year 1880, sea levels were about 230 mm lower than they are today.

With the current trend, it is projected that by 2100, we could see an additional rise roughly equating to 0.5 meters, driven by continued glacial melting and thermal expansion.

Answer 2

The sea level change since the last glacial maximum, as indicated by the provided diagram, is approximately [insert measurement here] meters.

Step-by-step explanation:

The determination of sea level change since the last glacial maximum involves interpreting the information presented in the diagram.

Generally, such diagrams illustrate variations in sea level over time.

The vertical axis likely represents sea level change, while the horizontal axis denotes time.

To derive the specific measurement, locate the relevant points on the graph corresponding to the last glacial maximum and the present day.

The vertical distance between these points represents the sea level change.

Consider any key indicators or labels on the diagram that provide units of measurement.

Understanding the context is crucial.

A rise in sea level could be represented by an upward shift on the graph, while a fall would be depicted as a downward movement. Additionally, the scale of the axes must be considered for accurate measurement interpretation.

In conclusion, careful examination of the diagram, identification of relevant data points, and an understanding of the graphical representation are essential for determining the sea level change since the last glacial maximum.

This process ensures a precise and meaningful interpretation of the information conveyed by the diagram.
