Explanation:
Lava Cools on the side of a volcano
Storms erode the hardened lava
Particles of hardened water settle at the bottom of lakes
Layers of sediments bond underwater
Plate movement bakes sedimentary layers.
Since the transition is from igneous to sedimentary to metamorphic rocks;
- Lava which is magma or molten rock that reaches the surface cools and solidifies to form a volcano.
- Weathering and erosion of the volcano then proceeds and sediments are formed
- The sediments are further carried underwater where they harden at bottom of lakes.
- Layers of the sediments bond and cements together underwater to form sedimentary rocks.
- Tectonic activities further bakes the layers to form metamorphic rocks.
Answer:
Heat from the mantle forms convection currents causing the tectonic plates to diverge and form ocean basins.
Explanation:
Ocean basins form as a result of convection in the mantle along divergent margins.
- At a divergent margin, new crusts are being formed.
- It is said to be a constructive margin because new materials reaches through to the earth surface from there.
- The mantle convection pushes materials up and down away from heating centers and to cold regions and back and forth.
- This leads to the creation of cells which moves the overlying plate.
- The mantle materials are then able to reach the surface to form new ocean basin.
The falaj system in was used to transport water to farms and villages
Answer:
They have reduced the river's force to almost nothing by the time it finally empties into the sea.
Explanation:
The Colorado River is one of the biggest rivers in North America. It runs mostly through the United States and little through Mexico where it ends its flow and empties into the sea. This river has been the subject of heavy exploitation by humans, and for that purpose, numerous dams have been built on it.
The number of dams is so high and the water is used at such a high rate that the river barely has any water as it empties into the sea. As this river runs mostly through arid and semi-arid areas that are also used for agriculture, its waters are heavily used for irrigation, leaving less and less water in the river as it gets closer to its endpoint. The dams are helping a lot in the economies of the states through which the Colorado River runs but the effect on the ecosystem of the river has been devastating.
well if she has 15 now then you add 3 to 2 which is 5 then add that to the 15 so you get 20 in total then minus th3 6 she made today you get 14 divided by 2 which is 7 she made 7 yesterday and 13 today which is 20 so the answer is 7
