What does evidence about ancient climates indicates?
The answer is A
Evidence about ancient climates indicate that?
glacial ice once covered much of what is now India and Australia
How are fossils good indicators of past climates?
Fossils serve as vital indicators of past climates by providing evidence of the types of organisms that existed in specific environments. For instance, the presence of certain plant or animal species, such as tropical ferns or corals, suggests warmer, more humid conditions, while others, like polar species, indicate colder climates. Additionally, fossilized remains can reveal information about the ecological conditions and atmospheric composition during the time they lived, allowing scientists to reconstruct ancient climates and understand climate change over geological time.
Clues to what ancient climates were like come from?
Clues to ancient climates come from various sources including ice cores, tree rings, sediment layers, and fossil records. By studying these natural archives, scientists can reconstruct past climates and understand how they have changed over time. This information helps us to predict future climate patterns and assess the impact of human activities on the environment.
Why do scientists study fossil record so carefully?
Scientists study the fossil record meticulously because it provides crucial insights into the history of life on Earth, including the evolution of species and the environmental changes that have occurred over millions of years. Fossils serve as evidence of past ecosystems, helping researchers understand biodiversity, extinction events, and the processes of natural selection. Analyzing these records also aids in reconstructing ancient climates and habitats, contributing to our understanding of current and future ecological shifts. Ultimately, the fossil record is a key tool for piecing together the complex story of life’s development over geological time.
What does evidence about ancient climates indicates?
The answer is A
What principle do scientists follow in studying ancient climates?
in studying ancient climates, scientists follow an important principle: if plants or animals today need certain conditions to live, then similar plants and animals in the past needed those conditions.
What evidence do scientists use to study the ancient dinosaur?
Scientists use mainly fossils.
Evidence about ancient climates indicates that what?
continents in the Southern Hemisphere today were once centered over the North Pole
Evidence about ancient climates indicate that?
glacial ice once covered much of what is now India and Australia
What the definition of trace fossils?
A type of fossil that provides evidence of the activities of ancient organisms.
Which type of rock provides the best evidence that Earth's environment has changed over time?
Sedimentary rock provides evidence of the different changes in the earth's environments. Evidence is deposited in layers which have characteristics of wet, dry, hot or cold climates.
An important principle scientists follow to determine ancient climates is?
The principle that scientist must follow to determine ancient climates is to realize that climatic changes that take place today are happening much faster than they did in ancient times. One way scientists calculate the speed of climate change is by looking at how far animals would need to migrate every year to keep a constant temperature.
What is paleo evidence?
Paleo evidence refers to the physical remains and traces of ancient life, including fossils, plant imprints, and geological formations, that provide insights into past ecosystems and climates. This evidence helps scientists reconstruct the history of life on Earth, understand evolutionary processes, and analyze environmental changes over geological time. By studying paleo evidence, researchers can gain a deeper understanding of how organisms adapted to their environments and how ecosystems have evolved.
What is the primary source of evidence proposed by scientists to support the theory of an ancient Earth?
The primary source of evidence proposed by scientists to support the theory of an ancient Earth is radiometric dating of rocks and fossils. By measuring the decay of radioactive isotopes within these materials, scientists can estimate their ages and establish a timeline for Earth's history that stretches back billions of years.
What kinds of evidence do scientists use to study early migration?
Scientists use a variety of evidence to study early migration, including genetic analysis of modern and ancient populations, archaeological artifacts, isotopic analyses of human remains to trace diet and geographic origin, and studies of ancient pollen and plant remains to reconstruct past environments. By combining these different lines of evidence, scientists can piece together the story of how humans migrated and settled around the world.
Archaeologists and historians have determined that ancient Nubia had a rich trade relationship with ancient Egypt. What provides the best evidence of this?
