Oldest to youngest- D, A, E, B, C
It's called relative dating, you basically find the rocks that are at the very bottom (oldest), look for the ones that are on the top (younger), but if you find any that are cross cutting, those are the youngest of them all.
Answer:
8 plants in the solar system
Answer:
secondary succession
Explanation:
In the described scenario we have a destruction of an ecosystem because of natural causes, volcano in this case. All that has left after the volcanic eruption has been barren land. After this has happened life started colonizing the volcanic island again, in a process known as primary succession. In the primary succession it is the organisms that have the lowest of requirements for survival that will inhabit the island. Over time, as they die, they will provide biomass for the ground, thus soil will start to form. Once there's soil formed a process called secondary succession will start. In this process the island will start to be inhabited by some plants and smaller animals. These plants and animals will contribute to further enhancing the living conditions on the island, and the island will gradually be getting larger plants and larger animals, thus a new ecosystem will be formed on the place of the old one.
Answer: Volcano
Explanation:
The Great Rift Valley is the site of major geological activity that stretches from Mozambique to the Middle East. Scientists believe that Africa and the Arabian Peninsula were joined together before they were separated by a process called rifting.
As the Earths tectonic plates begin to tear apart in this region, molten magma emerge from the earth crust to fill the void resulting in a separation.
Geologist estimates that the phenomenon which resulted in the great rift valley started 25 million years ago and gave rise to the Red sea. It is believed that the Indian Ocean flooded into the rift to form the Red Sea.
The.magma that seeps upward to fill crustal voids in the rift valley emerge mainly via volcanoes. Hence, many active and semi-active volcanoes are scattered throughout the region referred to as the Great Rift Valley, including Mount Kenya and Mount Kilimanjaro.
