Are limestone deposits are evidence of ancient tropical seas?
Many geologists believe that limestone deposits on land exist where ancient seas used to be. The moisture, over many centuries, created limestone.
Are limestone deposits evidence of ancient seas?
Limestone is a type of sedimentary rock comprised of minerals calcite and aragonite. Limestone deposits are evidence of ancient seas with some limestone being dated as far back as 470 million years ago on the area where North America now stands.
Where is limestone found in nature?
Limestone is commonly found in nature in areas with ancient sea beds, such as marine environments and seabeds. It is formed from the accumulation of marine life remains like shells and coral that undergo compression over time. Limestone can also be found in caves and cliffs formed by the erosion of these marine deposits.
Where is flint naturally found?
Flint is naturally found in sedimentary rocks, such as limestone and chalk, as well as in gravel deposits and riverbeds. It is commonly found in regions with ancient seabeds or where glaciers have deposited rocks.
Where can you find chert?
Chert can be found in sedimentary rock formations such as limestone and dolomite, as well as in areas where volcanic activity has occurred. It is commonly found in regions with ancient seas or lakes where silica-rich organisms lived and accumulated. Chert is also sometimes found in gravel deposits and within flint nodules.
What are the 5 pieces of evidence for wegners continental drift theory?
The five pieces of evidence for Wegener's continental drift theory are: (1) the fit of the coastlines of continents like South America and Africa, (2) the distribution of similar fossils and rock types on different continents, (3) the alignment of mountain ranges across continents, (4) the presence of ancient glacial deposits in tropical regions, and (5) paleoclimatic evidence such as coal beds in Antarctica.
What are three types of evidence for Pangaea?
Fossil evidence: identical fossils of plant and animal species have been found on continents that are now separated by oceans. Geologic evidence: similar rock formations and mountain ranges are found on opposite sides of different continents. Climate evidence: ancient climate patterns inferred from glacier deposits and coal deposits match up when continents are repositioned together as Pangaea.
What material were the pyramids stones composed?
The ancient pyramids were composed of limestone rocks. The limestone came from quarries on the banks of the Nile River.
What are Ancient Egyptian Templs made of?
Limestone.
Where is flint rock typically found in nature?
Flint rock is typically found in sedimentary rocks, such as limestone and chalk, as well as in gravel deposits and riverbeds. It is commonly found in regions with ancient seabeds or where glaciers have deposited rocks.
Where are limestone and sand stone found?
Limestone is a sedimentary rock formed of calcite or calcium carbonate deposits from ancient sea life. Sandstone is a metamorphic rock formed from sand which has been solidified by some geologic process. Quartzite, for example, is a type sandstone formed from solidified grains of quartz sand.
What are 3 types of evidence that support Pangaea?
Fossil evidence of similar plant and animal species found on different continents. Geological evidence of matching rock formations and mountain ranges on different continents. Climate evidence, such as glacial deposits and ancient climate patterns, that suggest continents were once connected.
