The second largest city in Brazil is Rio de Janeiro, while the third biggest is the capital Brasilia. Rio de Janeiro has an estimated population of around 6,5 million people while Brasilia has little less than 3 million. This makes Rio de Janeiro more than twice bigger in population than the capital of Brazil, Brasilia. But there's something interesting in here in the background, in the past 6 years the population of the second Rio de Janeiro has only increased by little over 9%, while Brasilia's population has increased by around 20% which is more than twice in increase, so if that trend continues in the coming few decades Brasilia will come on top of Rio de Janeiro very quickly.
Answer: Option (1)
Explanation:
The earth is made up of numerous small and large plates and they are considered as the lithospheric plates. They are of two types, namely the continental plate (crust) and the oceanic plate (crust). These plates constantly move over the layer of Asthenosphere due to the convection current that forms in the mantle. This currents are formed due to the heat energy radiated from the core of the earth.
This plate motion takes places in three forms, such as-
(a) Divergent plate motion
(b) Convergent plate motion
(c) Transform plate motion
In a convergent plate motion, two plates moves towards each other. It can be either continental-continental or oceanic-oceanic or oceanic continental collision. Due to this crashing of the plates, a subduction zone is formed that is marked by a deep sea trench and deep-focus earthquakes are generated. Also volcanic and island arcs are formed.
The Mariana trench is formed due to the collision between the Pacific plate and the Phillipine plate. It is the world's deepest trench having a depth of approximately 11 km.
Hence, the correct answer is option (1).
Answer:
The flow of energy is transferred from layer to layer of the earth.
Explanation:
Heat can be transferred from one thing to another and it's the same way for multiple things. Heat is one form of energy that can be transferred from one source to other objects possibly creating a cycle.
To form a fragmentary sedimentary rock, the fragments must be naturally compacted and cemented together.
Sedimentary rocks are made of sedimentary fragment and weathering from other rocks. Sedimentary rocks form at the Earth's surface, so they are easy to locate and study. An example of a Fragmentary Sedimentary rocks is shale.
