What can limestone deposits tell scientists about the environment in which they evolved?
Limestone deposits can indicate the past presence of shallow tropical seas or marine environments. Fossils found within limestone can provide insights into the organisms that lived in these environments and help reconstruct the paleoclimate of the area. Additionally, the composition and structure of limestone can reveal information about the sedimentary processes and tectonic history of the region.

Why do scientists save long tubes of ice?
Scientists save long tubes of ice, known as ice cores, because they contain information about past climate conditions, such as temperature, atmospheric composition, and precipitation. By analyzing the layers in ice cores, scientists can reconstruct past environmental changes and understand how the Earth's climate has evolved over time.
How right earths biogeochemical cycles help scientists to understand the early history of life on earth?
Studying Earth's biogeochemical cycles, such as the carbon and nitrogen cycles, can provide insights into how early life forms interacted with the environment and influenced chemical processes on Earth. By examining these cycles, scientists can infer how early life forms may have evolved, adapted to changing environments, and shaped the conditions necessary for life to thrive on Earth. This understanding can help reconstruct the early history of life on Earth and how it has influenced the planet's biogeochemical processes over time.
By testing soil composition in various locations scientists are able to determine the age of earth's?
By analyzing soil composition, scientists can determine the age of Earth's surface by studying the layers of sediment and rock. By dating the materials found in these layers using techniques like radiometric dating, scientists can estimate the age of the Earth and the events that have occurred over time. This information helps us understand the Earth's history and how it has evolved over billions of years.
What type of evidence acts as a record of changes in organisms over time and indicates major changes in earths surface and climate?
Fossils serve as evidence of changes in organisms over time and reveal major changes in the Earth's surface and climate. By studying the types of fossils found in different rock layers, scientists can understand how life has evolved and how the environment has changed over millions of years. This field of study is known as paleontology.
What can ice cores reveal about the earth's past?
Ice cores can reveal information about past climate conditions, including temperature, atmospheric gases, and precipitation patterns. By analyzing the composition of gases and isotopes trapped in the ice, scientists can reconstruct past environmental changes and understand how the Earth's climate has evolved over time. Ice cores also provide insights into natural events such as volcanic eruptions and can help researchers study the impact of human activities on the environment.
Why might scientists believe that life evolved as bacteria around deep sea vents?
Perfect environment: dark, wet, warm to hot.
What did scientists think life evolved from?
Scientists believe that life on Earth evolved from simple molecules such as amino acids and nucleotides that formed in early Earth's environment. These molecules gradually combined and evolved to form more complex molecules and eventually led to the emergence of living organisms. This process likely occurred over millions of years through a series of chemical reactions.
What do scientists think fish evolved from?
ampibians
What plants have been evolved in the forests that became coal deposits?
Pine trees.
Naracoorte caves fossils. are they extinict or evolved?
Both! The fossils within limestone holding caves are of long-extinct animals, but they had still evolved to the species preserved as fossils.
Why do scientists think that dinosasurs evolved into birds?
90% of modern birds
How do humans influence the environment?
Humans are the one that are affecting environment the most. They have evolved with technology has left the environment behind.
Why do scientists believe that birds evolved from dinosaurs?
Scientists believe birds evolved from dinosaurs because of several pieces of evidence, such as shared skeletal features, fossil records of "transitional" bird-like dinosaurs, and genetic similarities. These connections suggest that birds are the descendants of a group of small theropod dinosaurs.
Where do scientists believe plants evolved?
Scientists believe that plants evolved on land from green algae, specifically from a group called charophytes. This transition from water to land occurred around 450 million years ago during the Ordovician period.
How have organisms have evolved physiologically to become suited to its environment?

What animal do scientists think penguins evolved from?
Scientists think that penguins evolved from flying birds, similar to petrels and albatrosses, around 60 million years ago. Over time, they adapted to a more aquatic lifestyle, leading to their distinctive form and characteristics we see today.
What is an animal that evolved from the lungfish?
Most evolutionary scientists today do not think that amphibians evolved from the lungfish. They do share some characteristics, but the lungfish has no hint of legs.
