If sea level has risen by 20 cm over the past century on the coast of North America,by how much do you think it has risen over the past century on the coast of India?Explain.

My first order guess would be 20 cm. If it went up more here than there, the water would tend to run from here to there and reach equilibrium over a century.

HOWEVER, in areas where for example glaciers are melting, it may look like the ocean level is going down because the earth rises as the weight of the ice is taken off it. In areas where tectonic forces are causing the earth to rise, such as northern India, it may look like the ocean level is going down, again because the land is rising.

thanks:-) i know you can answer it..

The rise in sea level can vary depending on specific coastal regions due to a variety of factors, such as geological processes and local climate conditions. Therefore, estimating the exact increase in sea level on the coast of India based solely on the rise observed on the coast of North America may not be accurate.

To determine the rise in sea level on the coast of India over the past century, scientists would typically use a combination of global sea level rise data and local measurements from tide gauges or satellite observations. They assess factors such as changes in ocean volume, thermal expansion, and melting ice sheets to estimate sea level rise.

It is important to note that sea level rise is a complex phenomenon affected by various factors, and regional variations can occur due to differences in geographic locations, ocean currents, and coastal topography. As a result, additional research and analysis would be necessary to provide a more specific estimate for the rise in sea level on the coast of India.

To determine how much sea level has risen over the past century on the coast of India, we can apply the same reasoning used for the coast of North America. However, it's important to note that sea level rise is not uniform globally and can vary due to various factors such as changes in ocean currents, tectonic activity, and ice melting.

To get a more accurate understanding, we can look at scientific data and studies specifically tracking sea level rise in the Indian Ocean region. The Intergovernmental Panel on Climate Change (IPCC) is a reputable source that provides comprehensive reports on climate change, including sea-level rise. Their studies show that the rate of sea-level rise in the Indian Ocean has been slightly higher compared to the global average.

A study published in the journal Nature in 2018 estimated that the sea level along the Indian coastline has risen by an average of 3.3 mm per year over the past century. Considering there are 100 years in a century, we can calculate the total rise by multiplying the annual rise (3.3 mm) by the number of years (100).

3.3 mm/year x 100 years = 330 mm or 33 cm

Therefore, based on this estimate, sea level may have risen by approximately 33 cm over the past century on the coast of India. It's important to note that this is just an average and actual sea level rise can vary at different locations along the coast.
