d. giving them access to clean water
Answer:
b. each has its own geologic history.
Explanation:
An ocean is a body of salt water which covers approximately 70% of the Earth's surface. About 97% of the Earth's water is comprised of ocean and as such it is the most prominent and defined feature of the Earth. There are basically four (4) categories of an oceanic basin and these are;
<em>1. The Pacific ocean. </em>
<em>2. The Artic ocean. </em>
<em>3. The Atlantic ocean. </em>
<em>4. The Indian ocean. </em>
On the other hand, Continents can be defined as very large landmasses or area of land typically surrounded and separated by water. It is divided into seven (7) main categories and these are;
<em>1. Africa. </em>
<em>2. Asia. </em>
<em>3. Antarctica. </em>
<em>4. South America. </em>
<em>5. North America. </em>
<em>6. Australia. </em>
<em>7. Europe. </em>
Continents differ in appearance from ocean basins because each has its own geologic history. Thus, a continent is less denser and comprise of a thick granite material while an oceanic basin is dense and an older basalt.
When a continent is compared with an oceanic crust, it was discovered that the continental crust is lighter in colour than the oceanic crust.

Answer:
Explanation:
Biomass refers to the organic matter from plants and animals.
It is also a source of renewable energy which can be used to produce electricity.
Energy from biomass orginates from the process of photosynthesis where green plants manufacture food for the ecosystem using carbon dioxide and sunlight.
Biomass has the following use:
It is widely available: Biomass can easily be sourced for. It is widely abundant in the environment.
It is inexpensive: Due to its wide availability, its source materials are very cheap and lies readily in the environment when we compare this to exploration for fossil fuels and mining for uranium.
It is carbon neutral: Since biomass constitutes a part of the carbon cycle, energy from biomass does not lead to climate change. Green plants use carbondioxide to manufacture their food and it is released back to the atmosphere when biomass is tapped.
It is environmentally friendly: The use of biomass as a source of energy does not affect the environment negatively. It is a clean source of energy.
It helps to reduce amount of waste: biomass energy helps us put wastes into a very good use.
A no-discharge zone restricts the use of Type One and Two Marine Sanitation DevicesThese areas require greater environmental protection. Any sewage discharge in this area can be very harmful to the environment, including the flora and fauna of the zone.
