11 Nov 2009, 8:47 PM | Re: Enviro through time question- help plz ! Its because at this time there was no ozone layer to filter the UV rays. So therefore on land there were high amounts of UV rays. The water is a natural filter of UV rays hence there were lower levels of UV radiation here. I hope that answers it |
