These lava flows are Cenozoic in age, and some of them spill into the canyon.
The walls of the canyon are mostly cut into horizontal rock layers of Paleozoic age (green in Figure 1, above).
In essence, it is the largest terrestrial planet, but is smaller and less massive than any of the gas/ice giants of the Outer Solar System.
In addition to being the birthplace of humanity and the cradle of human civilization, Earth is the only known planet in our Solar System that is capable of sustaining life.
As a terrestrial planet, Earth is located within the Inner Solar System between between Venus and Mars (which are also terrestrial planets).
Basically, when the North Pole is pointing towards the Sun, the northern hemisphere experiences summer and the southern hemisphere experiences winter.
During the summer, the day lasts longer and the Sun climbs higher in the sky; while in winter, the climate becomes generally cooler, the days are shorter and the Sun appears lower in the sky.
And in the meantime, we can only hope that our presence here on Earth doesn’t ruin it.
