What is a time line that shows how conditions and organisms have changed on Earth?
A timeline illustrating the changes on Earth includes several key events: the formation of the Earth around 4.5 billion years ago, the emergence of simple single-celled organisms about 3.5 billion years ago, and the development of multicellular life around 600 million years ago. The Cambrian Explosion, approximately 541 million years ago, marks a significant increase in biodiversity. The age of dinosaurs dominated the Mesozoic Era (about 252 to 66 million years ago), leading to the rise of mammals and birds following the mass extinction event around 66 million years ago, which paved the way for the current diversity of life.
What else can I help you with?
How has the temperature of the earth changed?
The temperature of the earth has changed because of the atoms in the air has become polluted with poo fluids. Aspects of this shows that the earth is decresing in temperature according to the dogs and cats.
What are two things the paleontologists can learn from fossils?
1. When that animal/plant lived. 2.What killed that animal/plant.
What does the fossil record reveal about new species of organisms?
They evolved over time from older species.
What natural event most clearly demonstrates how to understand life on earth?
One natural event that demonstrates life on Earth is the changing of seasons. This event shows the interconnectedness of living organisms with their environment and how they adapt to the varying conditions. It also emphasizes the cyclical nature of life and the importance of balance and harmony in ecosystems.
How does the development of the theory of plate tectonics demonstrate scientific process?
it shows how the earth used to be and how it spread and changed over time
What evidence causes scientist to think that prokaryotes were the first organisms on the planet?
Scientists believe prokaryotes were the first organisms on the planet because they are simple in structure and lack a nucleus, making them more likely to have evolved early in Earth's history. Fossil evidence dating back over 3.5 billion years shows the presence of prokaryotic organisms, supporting the idea that they were among the earliest life forms. Additionally, prokaryotes are able to thrive in extreme conditions, similar to the conditions believed to have existed on early Earth.
What type of information does a physical map show?
A physical map shows the natural features of a location, such as mountains, rivers, lakes, valleys, and other physical characteristics of the Earth's surface. It provides detailed information about the topography and landforms of a region.
An ecosystem that has many different kinds of organisms shows?
An ecosystem that has many different kinds of organisms shows efficient biodiversity. Terrestrial biodiversity tends to be highest at the equator.
What does a yardstick character do?
Shows how a main character has changed
What shows which characteristics organisms share and when they evolved?
branching diagram
What does fossil evidence show about Earth's climate?
The fossil evidence shows that the Earth's climate before had high levels of carbon dioxide. The plants that evolved consumed this carbon dioxide out of the air and formed oxygen, coal, limestone, and other fuels.
A comparison of recently formed fossil types of living organisms shows that?
