A cavern is a large cave. Generally a cave is considered to be a cavern if it is large and extends a long way underground. Caverns often have other geological features within them such as stalactites or stalagmites. The exploration of caves and caverns is known as speleology.
So far, Earth is the only planet we know of that has intelligent life.
The planet Earth is the only planet which we know to contain life. There may be others, but we have not found them yet. So for now, Earth is unique.
An underground cavern is a large cave or chamber typically found beneath the Earth's surface. These formations are often created through geological processes such as erosion, dissolution of rock, or volcanic activity. Underground caverns can contain unique ecosystems and geological features.
This is one way that mountains form.
The amount of water on/in the Earth (the planet) has been fixed for eons of geological time and plays a part in the great geological processes. As the amount of water is fixed, your question is meaningless.
Geological processes are processes that shape or change the physical makeup of the planet. If you think about it you will realize that things like erosions, earthquakes, and meteor impact change the earth which makes them geological processes. (:
The Earth underwent geological processes and life on Earth underwent evolutionary processes and the two are inextricably linked. Life terraformed Earth.
There are seven main geological forces that shape the planet Earth. These forces are Aeolian processes, biological processes, fluvial processes, glacial processes, hill slope processes, igneous processes, and tectonic processes.
It's seas, that's why we're called the Blue Planet.
In the case of Earth, "active" means that the planet has geological processes happening that are moving and reforming the planetary crust. These processes are driven by heat from the planets core which cause the planets substance to convect slowly.
It is the only (known) planet to uphold life. -Katelyn, 6th grade
A geological disaster is when the structure of the earth changes.
