There isn't one single name for all earth scientists. Instead, the field encompasses a wide range of specialties, each with their own names. Here are some of the most common:

General Earth Scientists:

* Geoscientist: This is a broad term encompassing all Earth scientists.

* Earth Scientist: A slightly more specific term, often used interchangeably with "Geoscientist."

Specific Earth Science Fields:

* Geologist: Studies the solid Earth, including rocks, minerals, and the Earth's structure.

* Geochemist: Studies the chemical composition of the Earth and its processes.

* Geophysicist: Studies the physical properties of the Earth, including its gravity, magnetism, and seismic waves.

* Hydrologist: Studies water on Earth, including its movement, distribution, and quality.

* Meteorologist: Studies the atmosphere, weather, and climate.

* Oceanographer: Studies the oceans, including their currents, tides, and marine life.

* Paleontologist: Studies fossils and ancient life.

* Seismologist: Studies earthquakes and seismic waves.

* Volcanologist: Studies volcanoes and volcanic eruptions.

* Glaciologist: Studies glaciers and ice sheets.

These are just a few examples, and many other sub-fields exist within Earth Science. For example, there are specialists in:

* Petrology: The study of rocks

* Mineralogy: The study of minerals

* Stratigraphy: The study of rock layers

* Sedimentology: The study of sediments

* Geomorphology: The study of landforms

* Environmental Geologist: Studies the impact of humans on the Earth's environment

So, the next time you see an Earth scientist, you can ask them what specific area they specialize in!
