Question

Answer

These types of rocks are called sedimentary rocks. For example, sandstone is made from grains of sand. These rocks may also contain fossils of plants,animals and other micro- organisms that once lived on them. FossilsThe remains of the dead plants and animals trapped in the layers of rocks are called fossils.

Answer

It is fossils....

Answer

C) Fossils , is the correct answer

Answer

Fossils

Answer

1) fossils are preserved remains or traces of living thing .

2) most fossils from when living things die and are buried by sediments .

3) the sediments slowly harden into rock and preserve the shapes of the organisms .

4) paleontologists are scientists who study fossils

Answer

Fossils are the remains or traces of ancient plants and animals that are preserved in layers of rocks. They provide valuable evidence of the history of life on Earth and help scientists understand the evolution of different species over time. Fossils can be found in various forms, including bones, teeth, shells, imprints, and even preserved soft tissues.

Fossils are formed through a process called fossilization, which involves the gradual replacement of organic materials with minerals. Here is a detailed explanation of the formation of fossils:

1. Death and Burial: When an organism dies, it may get buried in sediment such as mud, sand, or silt. This burial prevents immediate decomposition and exposure to scavengers.

2. Sediment Accumulation: Over time, more layers of sediment accumulate on top of the buried organism, exerting pressure on it. This process is called sedimentation and can occur in bodies of water, such as rivers, lakes, or oceans.

3. Permineralization: As the layers of sediment continue to accumulate, the buried organism undergoes permineralization. This occurs when minerals, such as silica or calcite, carried by groundwater gradually replace the original organic materials of the organism, preserving its shape and structure.

4. Compression and Compaction: The weight of the overlying sediment compresses the layers beneath, leading to compaction. This process helps in the preservation of delicate structures, such as leaves or feathers.

5. Cementation: The minerals in the groundwater can also act as cement, binding the sediment particles together and forming solid rock. This process is known as cementation.

6. Geological Processes: Over millions of years, geological processes such as uplift, erosion, and weathering expose the fossil-bearing rocks at the Earth's surface. These rocks can be found in various layers or strata, providing a chronological record of the organisms that lived during different time periods.

Fossils are an essential tool for paleontologists and other scientists studying the history of life. By examining fossils, they can determine the age of rocks, reconstruct ancient environments, and trace the evolution of different species. Fossils also provide evidence for past climate change, the existence of extinct species, and the relationships between different organisms.

In conclusion, fossils are the remains or traces of ancient plants and animals that are preserved in layers of rocks. They are formed through a process of burial, sedimentation, permineralization, compression, compaction, cementation, and geological processes. Fossils provide valuable insights into the history and evolution of life on Earth.
