Most live animals are imported from Canada (around $2.8 Mil) followed by Mexico (around $2.5 Mil)
Answer:
Trees and Plants
Explanation:
Trees and plants in our communities are responsible for the maintenance of our ecosystem. There activities include carbon sequestration ( Plants remove carbon from the atmosphere and fix it in their tissues), generation of oxygen (they generate oxygen as a by-product when photosynthesis occurs), control of soil erosion ( it is well known that plants and trees help in erosion control. in fact places with trees and good vegetation cover rarely suffer the effects of erosion) and habitat provision for wildlife (countless species make the trees and plants their abode or habitat i.e where they live).
This shows how important plants and trees are to our ecosystem.

Answer:
D. it is part of a rift valley
Explanation:
Africa is believed to split in the future. There is still no consensus about how much will be needed for that, but it varies anywhere from 10 million years to 50 million years. There are several evidence that suggest to the geologists that this is happening, with the biggest one being the rift valley across the eastern portion of Africa.
The rift valley in Africa is actually a divergent boundary between the Nubian and Somali tectonic plates. The Somali plate moves eastward toward the Indian Ocean, thus separating itself from the larger Nubian plate.
The gap is becoming larger and larger every year, though for full separation of these two plates several millions of years will need to pass. Once the gap becomes wide enough and deep enough, the ocean water will fill it, thus making a natural barrier between the two plates, and thus creating a new separate continent.
Answer and Explanation:
Similarities between calcite and quartz
- They are both minerals.
- Although not often, they can both exhibit hexagonal and pyramidal shapes.
- Both are abundant on Earth.
Differences between calcite and quartz
- The property of hardness: Calcite is much less harder than quartz, while the latter is over three times harder than calcite.
- Their chemical composition: Although they are both minerals, their chemical composition significantly differs. Calcite is made from calcium carbonate while quartz is made from silicon dioxide.
- Their shape: The shape is one of the easiest way to identify minerals as you normally don't need to perform an experiment as the case of chemical composition differences. Quartz minerals usually exhibit hexagonal shapes while calcite minerals usually exhibit rhombohedron shapes.
