I am planning to show Urban Sprawl over a time period of 10 years. I am need of older Google earth image for the area. Also, let me know about the useful ArcGIS temporal tools for such analysis.
Since you are asking specifically for Google Earth, are you aware of the Historical Imagery setting? From your GE menu, View-->Historical Imagery. You will end up with a slide bar of historical imagery, which is dependent upon your area. You can slide through the imagery and see the differences in urban sprawl for your area
Alternatively you can use Google Earth Engine to use landsat imagery. This is one of the longest continuously measured remote sensing datasets. Resolution is 30m so hard to use for urban sprawl in smaller cities.
Add the Landsat TOA composite to your workspace: https://explorer.earthengine.google.com/#workspace
You could also this rather detailed urban extent database: http://www.lincolninst.edu/subcenters/atlas-urban-expansion/global-sample-cities.aspx
They will update the dataset soon (before Habitat III conference) to include 200 cities worldwide
