the difference is that the earth's theory is similar to that of a hypotheses , structure and compositional layer of the earth.
The two are completely unrelated.
earth is bigger than the moon
Airplanes are used for transportation within the earths atmosphere where as spaceships are for travel outside and eventually back into the earths atmosphere
The focus is the point in the earths crust where the earthquake originates and the epicentre is the point in the earths surface directly above the focus.
the mantle
The Earth's compositional layers in order of increasing density are the crust, mantle, outer core, and inner core. The crust is the least dense layer, while the inner core is the most dense layer.
An aircraft flies in the Earths atmosphere, whereas a spaceship flies above the atmosphere.
The inner core Is solid and the outer core in liquid
Earth's eccentricity Eccentricity is defined as the difference in shape between an ellipse and a perfect circle. In a similar fashion to Earth's obliquity, the more uniform Earth's orbit is (more like a perfect circle), the less difference there is in climate change throughout the year.
The densest layer of Earth's compositional layers is the inner core. Composed primarily of iron and nickel, it has a solid state due to the immense pressure at Earth's center, despite the high temperatures. The inner core is surrounded by the outer core, which is liquid and also primarily made of iron and nickel, but the solid inner core is denser than the surrounding layers.
Tides are caused by the moon's gravity acting on the Earths water.Tidal waves are caused by sudden underwater movements of the Earth during an earthquake
by the earths rotation around the sun and the pattern in day and night and how the earth moves and how the earth revolves and rotate around the sun.
