Answer:
The most recent eon is subdivided into three eras and eleven periods.
Explanation:
The geological time scale has been constructed so that it can help in better research and understanding of the past, as well as making it easier to distinguish the past and its characteristics at a certain time. There are larger and smaller divisions in the geologic time scale, with the eon being the largest unit, followed by era, and then period.
The most recent eon is the Paherozoic, starting from 542 million years ago and still going on. It is subdivided into three eras and eleven periods so far. The three eras are:
- Paleozoic
- Mesozoic
- Cenozoic
The eleven periods are:
- Cambrian
- Ordovician
- Silurian
- Devonian
- Carboniferous
- Permian
- Triassic
- Jurassic
- Cretaceous
- Tertiary
- Quaternary
Answer:
b) the Pacific plate has carried the volcanoes away from the hot spot that formed them
Explanation:
The Hawaiian islands all have volcanic origin. Some are not active, while some still are. All of these islands have been active volcanoes at one point of time, and they have been created by a hot spot that lies beneath the Pacific plate. The hot spot has such a power that it actually manages to break through the central part of the plate where its crust is the strongest and densest. As the magma manages to come out above the water, it manages to create volcanic islands. The Pacific plate though is moving, it is not static, so it drags the volcanic islands away from the hot spot, causing their extinguishing. As those islands are moved away, the hot spot creates new volcanic islands, and the process constantly continuous, resulting in a volcanic island chain.
Answer:
the U.S. southwest
Explanation:
Aridosols are desert soils, where plant diversity is very low and often nonexistent. These soils are formed in arid and semi-arid regions, such as those found in the Southwestern United States. These soils occur due to the insufficient amount of precipitation in the region, in addition, due to the low vegetation cover, the rain that falls in the region, manages to leach the soluble salts of the soil, allowing them to drain into the deeper layers of the soil, where they can form carbonate, gypsum or saliferous horizons.
The molten material from earth's mantle that hardens to form rock is called "LAVA".
