What are some reasons for exploring the mid Cayman Ridge?
Answer:
Since life on Earth predates photosynthesis
, the exploration of this deep-water environment that lacks any source of light could provide information on what those life forms looked like.
What is the most abundant source of methane in the Globe?
In addition to the human sources, methane is also produced in natural settings. The greatest natural source of methane is
wetlands
, which contribute 30% of global methane emissions. Other natural sources of methane emissions include the oceans, termites, permafrost, vegetation and wildfires.
Why fishing practices that affect deep sea corals are such a significant problem for deep sea ecosystems?
Terms in this set (9)
Explain why fishing practices that affect deep sea corals are such a significant problem for deep sea ecosystems. … Therefore,
when they are damaged, the entire ecosystem is affected and cannot be repaired quickly
. Damage done today might not be repaired for several hundred years.
How can microbes play a biological role in the ocean?
A bacteria colony on the ocean floor illustrates the ubiquitous nature of microorganisms. Marine bacteria play a major role
in the ocean’s nutrient cycles
. sewage into the oceans releases huge numbers of bacteria and viruses into the water. … The water that is contaminated by these microbes can be the source of diseases.
Why are microbes in the ocean important?
Marine microbes play many important roles in the Earth system: they
influence our climate
, are the major primary producers in the ocean, dictate much of the flow of marine energy and nutrients, and provide us with a source of medicines and natural products.
What role do microbes play in the ocean?
They are pervasive and play many different roles in the marine environment, from being
the base of the food chain, controlling much of the flow of marine energy and nutrients
, and being essential to the ocean’s health.
Why are coral reefs overexploited quizlet?

They are responsible for fouling fishing lines.
Which direction is the mid Cayman Rise spreading apart?
Continuing movement on the boundary and extension within the pull-apart led to the formation of an area of oceanic crust containing a
north-south
trending spreading center that remains active to the present day.
What ocean is the mid Cayman spreading Centre in?
The Mid-Cayman Spreading Centre in
the Caribbean Sea
is one of the world’s deepest seafloor spreading centres.
What are two natural sources of methane?
Methane is produced by the breakdown or decay of organic material and can be introduced into the atmosphere by either natural processes – such as the decay of
plant material in wetlands
, the seepage of gas from underground deposits or the digestion of food by cattle – or human activities – such as oil and gas …
