Earth Science
The permeability of the soil or rock material through which the water is moving and the slope or gradient of the ground surface are the two main factors that determine how easily water can move through the ground. A higher permeability allows water to flow more easily, while a steeper slope increases the rate of water movement downstream.

The two words "earth science" and "echo" are not the guide words for an earthquake. Earth science is the study of the Earth and its processes, while echo refers to a reflected sound wave. An earthquake is a sudden shaking of the ground caused by tectonic plates shifting beneath the Earth's surface.
The two factors, assuming in our earth planet, are object mass and its height away from the earth ground or any selected zero level.
The two main types of science are natural sciences, which study the physical world (e.g. biology, physics, chemistry), and social sciences, which study human behavior and society (e.g. psychology, sociology, economics).
There are two kinds of natural science. They are biology and chemistry. Sub branches include astronomy, physics, and earth science.
Earth science focuses on the study of the Earth's processes and systems, such as geology, meteorology, and oceanography. Environmental science, on the other hand, is a broader interdisciplinary field that studies the interactions between humans and the environment, including social, political, and economic aspects. While there is some overlap between the two fields, they have different focuses and objectives.
