A Thousand Years of Cloud - Asteroid and Glassy Sea

When the asteroid comes as the Scripture details and 1/3 of the fish and 1/3 of the sails are lost, some say the force of a mountain of millions of tonnes moving at thousands of kilometres per second will be like that of 50 billion nuclear bombs going off at once.

Revelation 8:8-9:

The second angel sounded his trumpet, and something like a huge mountain, all ablaze, was thrown into the sea. A third of the sea turned into blood, a third of the living creatures in the sea died, and a third of the ships were destroyed.

Most of the crust of the earth is Sand - Silicon Dioxide  - glass would result at least in the first 2 km of the crust all around the globe. 

One advantage that may result from the impact is the total vaporization of most of earth's oceans, at least at the side of impact.  These waters, if ejected with enough force, may reach geostationary orbit.  Perhaps a layer of permacloud will result.

The harmful radiation responsible for so much cancer and death on earth among all living beings would be halted.

The waters above would be restored once more.

1000 years within sight.

After the fright.
