Camels are called “ships of deserts” and “atta allah” because it is the only mean of transportation found in deserts. Which help human beings go from one place to another easily in the desert, they make life easier for traveling.
<u>Answer:</u>
<em>Convergent plate boundary is rich in gold and silver.
</em>
<em></em>
<u>Explanation:</u>
There are three types of plate boundary such as Convergence, Divergence and Transform plate boundary. Most metallic minerals found in convergence plate boundary. Gold and silver are deposited in both convergent and divergent margins but rich in Convergent plate margin. Precious metals such as plutonium, gold, silver, etc. are mostly found in convergence of two plates. Convergence occurred in three ways such as Continent–Continent, Ocean–Ocean, Continent–Ocean.
<u>Answer:
</u>
The process of thick sediment layers to "accumulate" along the "boundaries of continental and oceanic plates" is called Subduction.
<u>Explanation:
</u>
- During a marine transgression, sea level raises high compared to land level resulting in floods. These are triggered during climate changes, ice-age, isostatic movements.
- Subduction occurs at the tectonic plates where one plate is moves under another forcing to sink into Earth’s mantle due to the gravitational force.
- The plates are continental and oceanic in the zone of lithosphere. The rate of subduction is usually seven to 8 centimetres per year.
- Marine regressions are opposite to transgressions where sea levels fall compared to land levels.
- Glaciation is the interval of time within an ice-age. The current glacier period is of Holocene.
