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.
Who were the two scientists who proposed the theory of sea floor spreading in the early 1960's?
The two scientists who proposed the theory of sea floor spreading in the early 1960s were Harry Hess and Robert Dietz. They presented the idea that new oceanic crust is formed at mid-ocean ridges and then moves away from the ridges, eventually sinking back into the mantle at subduction zones.
What is seafloor spreading that ''helps'' the theory of continental drift?
How seafloor spreading helps to explain the theory of continental drift is that wegener couldn't explain why and waht force caused the continents to move and so seafloor spreading helps to explain the theory of continental drift because it shows the force that made the continents move and that was te only thing that wagener needed to prove his theory of continental drift............thanks
Which theory is supported most by the finding that the moon is similar in composition to the outer portions of Earth?
The "giant impact" theory. The most popular current theory of the Moon's formation is that during the early times of our solar system very shortly after its formation, another planet perhaps as large as Mars collided with the proto-Earth. The cores of the two planets merged (resulting in the unusually massive iron core of the Earth) and the debris blasted into space by the collision partly fell back to Earth and partly formed the Moon.

Which three scientists directly contributed evidence for the cell theory?
Ah, the cell theory is a beautiful thing, isn't it? Three scientists who directly contributed evidence for this theory are Matthias Schleiden, Theodor Schwann, and Rudolf Virchow. Each of them played a special role in helping us understand the importance of cells in living organisms. Just like how each brushstroke adds to a masterpiece, their work has helped create a beautiful picture of life at the cellular level.
Who developed cell theory?
This happened in the 15th century known as 1600s Robert Hooke, Anton Van Leuwenhoek, and Theodor Schwann, and Matthias Schielden are discovery and observatory to this.The Cell Theory was first discovered in 1836.
Who discovered cancer cells?
Some descriptions of cancer go back to ancient Egypt as far back as 1600 BC and the understanding of cancer was significantly advanced during the Renaissance period. However, Sir Rudolf Virchow, a German biologist and politician, is generally credited with discovering the first cancer cells. As Giovanni Morgagni had linked autopsy findings seen with the unaided eye with the clinical course of illness, so Virchow correlated the microscopic pathology.
Which experiments led to changes to the original cell theory?
Back then, Robert Hooke found cells from a cork and named it cells. Later on, Matthias Schleiden found cells from plant parts and concluded that all plants are made of cells. Theodor Schwann, after observing many different animal cells, concluded that all animal have cells. Several years later, Rudolf Virchow hypothesized that cells divide to form new cells. Virchow proposed that every living organism has cells. His observations and conclusions and those of others are summarized in the cell theory.

Who discovered esophagus cancer?
Esophageal cancer, like many diseases, was not "discovered" by a single individual but rather identified over time through the study of symptoms and pathology. The first detailed descriptions of esophageal cancer can be traced back to the early 19th century, with significant contributions from pathologists like Rudolf Virchow. Advances in medical understanding and technology have since improved diagnosis and treatment, but the disease itself has been recognized for centuries.

What is an explanation in science that has a lot of evidence to back it up?
I think it is theory
How is a hypotheseis different from a theory?
A theory has been proven and has lots of data to back it up while a hypothesis is simply an educated guess that has some data to back it up.
Who proposed the theory that light light consists of two transverse waves vibrating back and forth at right angles to each other?
James Clerk Maxwell proposed the theory that light consists of two transverse waves vibrating back and forth at right angles to each other. This theory is known as electromagnetic theory of light.
