The scientists who helped determine the shape of DNA were James Watson and Francis Crick.
The size and shape of the Earth's core can be used to measure its properties by studying seismic waves that pass through the Earth. By analyzing how these waves travel and are affected by the core's size and shape, scientists can determine important properties such as density, composition, and temperature of the core.

Scientists use radiometric dating to determine the age of the Earth by measuring the decay of radioactive isotopes in rocks and minerals. By analyzing the ratio of parent isotopes to daughter isotopes, scientists can calculate the age of the Earth based on the rate of decay of these isotopes.
Yes, scientists can track the movement of water on Earth through the water cycle, which includes processes like evaporation, condensation, and precipitation. By studying these processes, scientists can determine if water ever leaves the Earth's system.
Scientists often determine the shape of a molecule using techniques like X-ray crystallography, nuclear magnetic resonance (NMR) spectroscopy, or computational modeling. These methods help visualize the arrangement of atoms in a molecule, allowing scientists to understand its three-dimensional structure and shape.
Scientists study deuterium in water because it can provide clues about the origin of water on Earth. Deuterium is an isotope of hydrogen that can help differentiate between water from sources like comets, asteroids, or Earth's mantle. By analyzing the deuterium content in water, scientists can determine where that water may have come from in the early stages of Earth's formation.
Early scientists believed that the Earth was flat, based on observations and theories available at the time. It wasn't until later advancements in science, such as the observations of celestial bodies and exploration of new lands, that the understanding of the Earth's shape evolved to being round.
Scientists determine the age of the Earth through radiometric dating methods, which analyze the decay of radioactive isotopes in rocks and minerals. By studying the composition of soil in different locations, scientists can establish a timeline of geological processes that have shaped the Earth, providing insights into its age and history.
They might have thought the earth is a square shape when it is a round shape!I hope that answers your question!
Scientists determine other features of the Earth through various methods, including satellite imaging, ground surveys, geological mapping, and remote sensing technologies. These tools help scientists identify and study features like topography, land cover, geology, and natural resources across different regions of the Earth. By combining data from these sources, scientists can create detailed maps and models to understand and analyze the Earth's various features.
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.
