Answer 3

I don't know where or how that much water the God Yahweh used in Noah's flood got here. What I do know is that as the sea level rose around the world it would have pushed the atmosphere up with it maintaining the oxygen level and air temperature as the same before the flood. This would have made it possible for Noah, his family and the modern species of animals in the ark to survive the short time they spent in the ark. When the sea level started to go back down Noah and his family and the animals would have had to abandon the ark at the top of the mountain that it landed on and follow the sea level back down the mountain, which might only have been less than ten years. The vegetation would have regrown on the exposed land above sea level thus resupplying oxygen around the world. There is much more I can write on this subject to support what I'm saying but don't have the time to right now.

The mass of the Earth is approximately 5.98×1024 kg. It is composed mostly of iron (32.1%), oxygen (30.1%), silicon (15.1%), magnesium (13.9%), sulfur (2.9%), nickel (1.8%), calcium (1.5%), and aluminum (1.4%); with the remaining 1.2% consisting of trace amounts of other elements. Due to mass segregation, the core region is believed to be primarily composed of iron (88.8%), with smaller amounts of nickel (5.8%), sulfur (4.5%), and less than 1% trace elements.

The geochemist F. W. Clarke calculated that a little more than 47% of the Earth's crust consists of oxygen. The more common rock constituents of the Earth's crust are nearly all oxides; chlorine, sulfur and fluorine are the only important exceptions to this and their total amount in any rock is usually much less than 1%. The principal oxides are silica, alumina, iron oxides, lime, magnesia, potash and soda. The silica functions principally as an acid, forming silicates, and all the commonest minerals of igneous rocks are of this nature. From a computation based on 1,672 analyses of all kinds of rocks, Clarke deduced that 99.22% were composed of 11 oxides All the other constituents occur only in very small quantities
The Earth's terrain varies greatly from place to place. About 70.8%[43] of the surface is covered by water, with much of the continental shelf below sea level. The submerged surface has mountainous features, including a globe-spanning mid-ocean ridge system, as well as undersea volcanoes,oceanic trenches, submarine canyons, oceanic plateaus and abyssal plains. The remaining 29.2% not covered by water consists of mountains, deserts, plains, plateaus, and other geomorphologies.

Answer 5

Total surface area: 510,065,600 km²

Total land surface:148,939,100 km² (29.2 %)
Total water surface: 361,126,400 km² (70.8 %)
