Although the New Earth will be renewed, it will not have many of the things of the old Earth. It will be configured geographically in a different manner. The old Jerusalem will be gone and the new Jerusalem will replace it. The sea will be gone. There will be new rivers, new plant growth, new mountains/valleys, etc. Former things will not be remembered.
