Because you are seeing clouds.
A mesa is formed through a combination of geological processes such as erosion and uplift. Over time, the surrounding land erodes away, leaving a flat-topped mountain or hill with steep sides. The erosion-resistant top layer of rock is what forms the flat tabletop of a mesa.
Clouds form on top of mountains primarily due to orographic lift, where moist air is forced to rise as it encounters the mountain's slope. As the air rises, it cools and expands, leading to condensation of water vapor and the formation of clouds. This process is often enhanced in areas with high humidity, resulting in cloud formation, especially on the windward sides of mountains. Ultimately, the presence of mountains acts as a barrier that influences local weather patterns and moisture accumulation.
Gravity is a property of a mass. Even you generate your own gravity field, though it is too small to be simply detected. So, as long as the mass exists, gravity will exist. In the 18th century, an experiment was made to determine the mass of the Earth. For this, the investigators measured the mass of a small mountain named Schiehallion in Perthshire. This experiment measured the deflection induced in a pendulum by the mass of this mountain. Measured on opposite sides of course, and consisted of measuring the apparent position (astronomical angle) of some stars. The difference between the two sets of measurements was due to the gravitation attraction of the mountain.

A flattop mountain is called a mesa. Mesas are elevated landforms with flat tops and steep sides, often found in arid regions.
A mountain gully is often referred to as a ravine. It is a deep, narrow valley with steep sides, typically formed by running water erosion.
a plateau.
The sides of a mountain are called slopes. These slopes can vary in steepness and play a role in determining the overall shape and characteristics of the mountain.
The correct term is a volcanic plug, which is a tall and narrow volcanic mountain formed around a vent with steep sides. They are often the solidified remnants of volcanic pipes that once transported magma from deep within the Earth to the surface.
