Which of the following ocean-floor features is associated with trenches?

2 answers:

6 0

The ocean-floor feature that is associated with trenches is a subduction zone. An oceanic trench is characterized by a narrow and very deep depression on the sea floor. This depression is caused by a subduction zone wherein two plate boundaries converge and one sinks at the bottom of the other plate, forming a thin and deep region between the two plates.

3- True

4- True

Explanation: Black smokers are generated in the mid oceanic ridges and during the underwater volcanic eruption, which is a hot vent releasing black colored smokes of sulfur from it. They are often associated with the Volcanogenic Massive Sulfide (VMS) deposits.

The lithosphere is the rigid broken plates that are relatively cool and flows over the weaker and viscous asthenosphere layer.

When the groundwater flow intersects the ground level, it forces the water to come out to the surface forming a spring.

The study of changing atmospheric composition along with the ice cores, helps in determing the age upto 800,000 years. But recently, a new discovery has made, in which the ice cores helped in dating back to about 1.5 million years.

just olya [345]

Answer:

Solar energy

Explanation:

Solar energy is renewable and a very cheap energy source that can easily be harnessed for a wide range of uses domestically and industrially.

Solar energy is sourced from the sun. Nuclear fusion within the sun releases a massive amount of energy into the solar system. The sun furnishes the solar system with insolation which can be used by living organisms and can be converted to other sources of energy.

This energy source is free and very much available almost all year round.

Overview: Choose two categories of natural resources (i.e., plants, animals, soil, minerals, air, water, or energy sources). The

Usimov [2.4K]

Answer and Explanation:

1. Natural resources are those things which are found on the Earth without human exertion and they are of two kinds which are as per the following:

Renewable natural resources :

It is a sort of natural resource which can be utilized over and over and they are not going to end sometime in the not so distant future, for instance, wind, sunlight based vitality, water, plants, etc.

Non-renewable natural resource :

It is a sort of natural resources which are present in very limited quantity and it will end on someday, for example, Coal, petroleum, minerals, etc.

2. Human beings are mostly depended on natural resources and it makes their life easy and comfortable. Let's see its usages one by one.

Historical: Historically, we depended on the renewable natural resources, for example, plants, animals, water and our life started and ended with this form of natural resources when we were not technically advanced.

Present: Presently, we are more technologically advanced and using various technologies to lead our life and we are using fossil fuels at a greater extent and within 30 to 50 years this non-renewable source is going to end and we need to choose our alternative ways also.

Future potential: The way non-renewable natural resources are declining by our present use, we need to switch to renewable sources which are long lasting as well as eco-friendly and that's why the renewable natural sources would be in more demand in near future.

3. These two categories are inter-related because they both provide the energy requirements of the present time, as well as non-renewable natural resources, are formed by the help of renewable sources since the long geological process.

4. we are vastly using now-renewable sources like petroleum, coal and renewable natural sources like solar energy, wind for our need for energy requirements
