What have scientist inferred from fossil stromatolites?
Stromatolites were much more abundant on the planet in Precambrian times which means that fossils found around stromatolites are typically from the Precambrian era.
The four outer planets do not have solid?
surfaces
What part of a cave are stromatolites found in?
Stomatolites are not usually found in caves. They are usually found in hyper saline lakes and marine lagoons.
How do the surface materials of the inner and outer planets differ?
The inner planets' surface materials differ from the outer planets because the inner planets have rocky surfaces and the outer planets have gas surfaces.
How do inner planets differ from the outer one?
They have rocky surfaces.

A Phospholipid molecule has a head and the two tails are found where?
the head are found at the inner and outer surfaces of the cell membrane while the tails are at the center or the middle of it
What is the molecule found on the outer surfaces of cells that the immune system recognizes as either part of the body or an outsides invader?
receptors
Name of the oldest fossil found in Australia?
The oldest fossils in Australia are 3.5 billion year old stromatolites. Stromatolites are layered accretions of prokaryotic microbes, most often made up of photosynthetic organisms. Stromatolites still live in Australia today.

The inner planets' surface materials differ from the outer planets because the inner planets have rocky surfaces and the outer planets have gas surfaces.
When did Stromatolites become extinct?
The are examples of stromatolites still living. They are not extinct.
How do inner planets differ from the outer one?
They have rocky surfaces.
What (who)are stromatolites?
The stromatolites are the layered mounds, columns, and the sheet-like sedimentary rocks.
Are gas giants a surface type?
Yes because the four outer planets,Jupiter, Saturn, Uranus, and Neptune are gas planets. They are known for their gas. The outer planets (closer to the sun) have rocky surfaces. So the outer planets have gas surfaces
Why are the surfaces of the inner planets rocky and solid yet the surfaces of the outer planets are gasous with icy centers?
There is no particular reason why the outer planets are gas and the inner planets are rock, but the outer planets have icy cores because they are all far away from the sun.
