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.
How do the surface materials of the inner and outer planets differ?
The inner planets (Mercury, Venus, Earth, Mars) have rocky surfaces composed of silicate minerals and metals. The outer planets (Jupiter, Saturn, Uranus, Neptune) have gas surfaces, primarily composed of hydrogen and helium. Additionally, outer planets may have icy surfaces due to the presence of water and other ices.
What part of a cave are stromatolites found in?
Stromatolites are typically found in shallow marine environments within a cave, such as near the cave entrance where light can penetrate for photosynthesis to occur. These microbial mats form layers of sediment and minerals over time, creating structures that can be observed in cave environments.
How do inner planets differ from the outer one?
They have rocky surfaces.
Which is not true in the inner planets?
The inner planets are closer to the Sun compared to the outer planets, have solid rocky surfaces, and are smaller in size compared to the outer planets.
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.
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
When did Stromatolites become extinct?
The are examples of stromatolites still living. They are not extinct.
What (who)are stromatolites?
The stromatolites are the layered mounds, columns, and the sheet-like sedimentary rocks.
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.

Additionally, outer planets may have icy surfaces due to the presence of water and other ices.
Where do stromatolites form today?
Stromatolites form in shallow, saline or hypersaline environments such as coastal lagoons, estuaries, and hypersaline lakes. They are also found in some marine environments where conditions are suitable for their growth, such as in the Bahamas and Shark Bay in Australia.
What part of a cave are stromatolites found in?
Stromatolites are typically found in shallow marine environments within a cave, such as near the cave entrance where light can penetrate for photosynthesis to occur. These microbial mats form layers of sediment and minerals over time, creating structures that can be observed in cave environments.
What creature is found in stromatolites?
Stromatolites are primarily formed by the activity of cyanobacteria, which are photosynthetic microorganisms. These bacteria create layered structures by trapping sediments and precipitating calcium carbonate, leading to the formation of these ancient rock-like formations. While stromatolites are associated with microbial life, they can also host a diverse range of other microorganisms and small invertebrates in their ecosystems.
How do inner planets differ from the outer one?
They have rocky surfaces.
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
Which is not true in the inner planets?
The inner planets are closer to the Sun compared to the outer planets, have solid rocky surfaces, and are smaller in size compared to the outer planets.
