Answer:
Terrigenous
Explanation:
The sediments must have been land derieved.
Garnet and zircon are found associated with igneous and metamorphic rocks.
Weathering of these rocks release the minerals into sediments and are hereby transported into ocean basins. They can lithify in the sediments as they get carried along with them.
Terrigenous sediments originates from the land. They are made of rock materials and volcanic deposits. Some of them like volcanic dusts can travel into deeper parts of the oceans as they are lighter and can be carried very far into the ocean.
Question
Mid-ocean ridges are steeper and less broad than rises because:
Group of answer choices
A) the rocks of the mid-ocean ridges are composed of more dense mineral than the rises.
B) the rocks of the mid-ocean ridges are composed of less dense mineral than the rises.
C) The seafloor spreading rate of ridges are faster than rises causing the oceanic crust to subside closer to the ridge axis.
D) The seafloor spreading rate of ridges are slower than rises causing the oceanic crust to subside closer to the ridge axis.
E) Every ridge is composed of continental crust.
Answer:
The correct answer is D.
Explanation:
In volcanic regions, as the molten magma flows out onto the seafloor creating new beds, the faster it flows, the less steep the mid-ocean ridge is. If however, it is slow-flowing, then oceanic lithosphere formed cool closer to the ridge axis thus making it very steep.

Answer:
I believe it is C, please correct me if it is incorrect.
Explanation:
Some parts of the route will be mountains, rocky roads, etc. Therefore it will gradually increase.
Explanation:
A major problem with using 15 years of data to predict 100 years of data is that the 15 years could have been setting a trend, then level off.
For example, if the 15 years of data was a graph, and it was going up every year, then what if 20 years into the 100 years it stops going up? Then that means the data was invalid because there wasn't enough to base any trends off of.
You can prevent this from happening by extending the collection time of data and to reduce the amount of time that the data will be used to predict.
Hope this helps!
Answer:
Certain process that deals with atmospheric emission are given as under.
Explanation:
Atmospheric emission is the root cause of diffusion pollutant gases in the earth's environment. Mostly caused due to the contamination the air by aerosols.
Certain process used to deal with such type of atmospheric emissions. Like
1. Measuring the pollutant content of air.
2. Keeping a check on vehicular emissions.
3. Meeting the set targets or goals set up by the United nations.
4. Proper disposal of wastes and proper solid waste management.
5. Cleaning and purification of rivers on a daily basis.
6. reducing the use of fertilizers, pesticides and insecticides.
7. Controlling the impact of fossil fuels, and banning plastic burning.
8. Reducing global warming and climate change impacts.
