"what evidence exists that some of the asteroids were geologically active in the distant past"

1 answer:

4 0

The geological activity of a celestial body like a planet, satellite or asteroid can be determined by looking at the surface features like the presence of a valley like terrain or plains or basins created by the lava flow. The presence of heavy elements like uranium, lead, iron and gold on the surface also indicate that the body once spewed out lava since these are found within the internal core of the body. Ceres, an asteroid has these elements present on its surface which hints at the presence of an active geological process in the past.

1. Biogeography, the study of the geographic distribution of plants, animals, and other forms of life. It is concerned not only with habitation patterns but also with the factors responsible for variations in distribution.

2. weathering and other natural forces break down the substrate, rock, enough for the establishment of certain hearty plants and lichens with few soil requirements, known as pioneer species. These species help to further break down the mineral-rich lava into soil where other, less hardy species can grow and eventually replace the pioneer species. In addition, as these early species grow and die, they add to an ever-growing layer of decomposing organic material and contribute to soil formation. This process repeats multiple times during succession. At each stage, new species move into an area, often due to changes to the environment made by the preceding species, and may replace their predecessors. At some point, the community may reach a relatively stable state and stop changing in composition. However, it's unclear if there is always—or even usually—a stable endpoint to succession.

3. I don’t have the video so I’m going to take. Wild guess. Just look up types of finches

4. Broadly speaking, different species are unable to interbreed and produce healthy, fertile offspring due to barriers called mechanisms of reproductive isolation.
These barriers can be split into two categories based on when they act: prezygotic and postzygotic.
