A geophysicist is a scientist who studies processes that change and shape the Earth

Geomorphologists study the surface of the earth. They conduct scientific studies of landforms and their shapes to understand landform history and to be able to make predictions about changes through the use of various scientific methods, such as numerical modeling, field observations and experimentation .

The different shapes of the moon are caused by its position relative to the Earth and the Sun. As the moon orbits the Earth, the amount of sunlight that reflects off its surface changes, creating the different phases we see from Earth.
Studies do not change the face of the Earth. That would be a bit like saying that studying a book changes the book. It does not. Studying is primarily an act of observation and, while it can occasionally be intrusive (such as when drilling into the Earth) this has little or no geological impact upon the face of the Earth. Studies that look into changes upon the solid face of the Earth, however, include geography and topography, or geology in general.

The natural process in which water, wind, or ice changes the shape of Earth's crust is called erosion. Erosion occurs when these elements wear away rocks and soil, transporting sediment to new locations. Over time, this process shapes landscapes, creating features such as valleys, canyons, and coastal cliffs. It is a key component of the rock cycle and contributes to the continuous reshaping of the Earth’s surface.
