What process provides the best evidence that Earth has evolved over geologic time?
The process of radiometric dating provides some of the best evidence that Earth has evolved over geologic time. By measuring the decay of radioactive isotopes in rocks and minerals, scientists can determine the absolute age of geological materials, helping to establish a timeline of Earth's history.

What is an example of a sudden geologic process?
An example of a sudden geologic process is a volcanic eruption. These events can release massive amounts of lava, ash, and gases in a short period, causing rapid changes to the landscape and environment.
What geologic process can change any type of rock into sediment?
Weathering and erosion
What geologic process is most responsible is soil formation?
Weathering is the most responsible geologic process for soil formation. This process involves the physical and chemical breakdown of rocks into smaller particles, which eventually become the foundation for soil development. Organic matter, such as decaying plant material, further contributes to the accumulation of soil over time.
The dating process that places geologic events in proper sequence is?
The dating process that places geologic events in proper sequence is called relative dating. This method involves determining the chronological order of events without assigning a specific age in years to each event. Relative dating relies on principles like superposition, cross-cutting relationships, and the law of faunal succession to establish the sequence of events.
How is weathering related to the geologic cycle?
Weathering is a key process in the geologic cycle as it breaks down rocks into smaller particles through mechanical or chemical processes. These weathered materials are then transported and deposited through erosion and sedimentation, which are also part of the geologic cycle. Weathering ultimately contributes to the transformation of rock materials over time, playing a vital role in shaping our planet's surface.
How are vestigial structure an example of evidence evolution?
Vestigial structures are remnants of features that were functional in the ancestors of a given species but are no longer useful in the current species. This supports the idea of evolution as it suggests that species have evolved over time from ancestors with different anatomical features. The presence of vestigial structures provides evidence of common ancestry and the gradual changes that have occurred over time through the process of evolution.
What are geological feature?
Geologic features are any physical features on the surface of a planet or moon, or of the rocks exposed at the surface, by any geologic process.
What is this geologic process called when water splits a rock?
Mechanical weathering.
Examples of biochemical evidence of evolution?
Physiological similarities suggest the species evolved from the same ancestor.
What is the remains of organisms preserved by geologic process?
The remains are called fossils.
Are fossil fuels produced today the same geologic process as in the past?
Yes.
Which organelle indicates that eukaryotic cells have evolved from prokaryotic cells?
Mitochondria, which are thought to have originated from a symbiotic relationship between early eukaryotic cells and aerobic bacteria, provide evidence that eukaryotic cells have evolved from prokaryotic cells. Mitochondria have their own DNA and ribosomes, similar to prokaryotic cells, and carry out cellular respiration, a process that is also similar to bacterial metabolism.
What is an example of a sudden geologic process?
An example of a sudden geologic process is a volcanic eruption. These events can release massive amounts of lava, ash, and gases in a short period, causing rapid changes to the landscape and environment.
Eplain the process of the examination of physical evidence and the significance of physical evidence?
The examination of physical evidence involves collecting, preserving, analyzing, and interpreting evidence found at a crime scene. This process helps forensic scientists and investigators reconstruct events, identify suspects, and establish connections between individuals and crime scenes. Physical evidence is significant as it provides objective information that can support or refute witness statements, ultimately helping to piece together the truth of what happened.
Did humans evolve?
Yes, humans evolved from earlier species over millions of years through a process known as biological evolution which is supported by scientific evidence.
What states the the same geologic process that's happening now happen in the past?
Uniformitarianism
What is the hypothesis supported by evidence from what record?
The hypothesis supported by evidence from the fossil record is that species have evolved over time through a process of natural selection, leading to the diversity of life we see today. This evidence comes from the ordered succession of fossils in sedimentary rock layers that show gradual changes in species characteristics over millions of years.
