Astronomers are considered earth scientists because they study celestial bodies such as stars, planets, and galaxies from a scientific perspective. Their work often involves understanding how these celestial bodies interact with Earth and the impact they have on our planet's environment and climate, making their research relevant to the study of Earth as a whole.
Scientists think the Earth's core contains iron because of the planet's magnetic field. Iron is a magnetic material, and the Earth's magnetic field is generated by the movement of molten iron in the outer core. Additionally, seismic waves and the density of the Earth indicate a high concentration of iron in the core.
Scientists think Earth's core is made of iron because iron is a dense material, and it is abundant in Earth's crust. Also, studies based on seismic waves and Earth's magnetic field support the idea that the core is composed mostly of iron.
Scientists think that plate motion is the result of the movement of material in the Earth's mantle. This movement is driven by processes such as mantle convection, where hot material rises and cool material sinks, generating forces that cause the tectonic plates to move.
Scientists study Earth's interior to better understand the planet's composition, structure, and dynamics. This helps in predicting natural disasters like earthquakes and volcanic eruptions, as well as in understanding processes like plate tectonics and magnetic field generation. Studying the Earth's interior also provides insights into the planet's history and evolution.
Scientists estimate that the Earth formed about 4.5 billion years ago. This estimate is based on dating of rocks and meteorites, as well as analysis of the solar system's formation.
Because they study many planets and their geography and atmosphere, in Earth Science you study the geology of Earth just like Astronomers study geology of other planets.
Astronomers study celestial objects such as stars, planets, and galaxies, which are located in space above Earth. While astronomers may not focus on the geology or atmosphere of Earth, their work is still aligned with studying the natural phenomena of the universe, making them closely related to Earth scientists.
it is earth
No, not all astronomers consider Pluto a planet. Pluto was reclassified as a dwarf planet in 2006 by the International Astronomical Union, leading to debate among scientists about its classification. Some astronomers argue that Pluto does not meet all the criteria to be considered a full planet.

People thought the earth was in the center of the solar system
Astronomy is one of the space sciences, but it is often combined academically, into the category of Earth and Space sciences, both of which are involved in large scale observations about the universe in which we live. Astronomers study planets in general (among other celestial objects), and the Earth is a planet.
There's a few different theories on this, but today, most astronomers feel that very early in earth's history - when it was still essentially a ball of molten rock - Earth was impacted by another huge object, perhaps half the size of earth. This blasted out a huge chunk that fell into orbit around the earth, and eventually became the moon.
