Answer:

Principal characteristics of a slate are:

It's a Metamorphic rock

As e metamorphic rock it is Foliated

It's origin is Regional metamorphism

Is a fine-grain rock, for that reason it has non-visible minerals

A slate is composed by principally by clay and Micas.

Explanation:

Slate rocks are fine-grain metamorphic rocks which original rock use to be a shale or a vocanic rock. It is foliated, becase of compression stress produced by regional metamorphism, it means, orogenic metamorphism common in compresive plate boundaries. The foliation are planes perpendicular to the stress direction. It has non visible minerals because of the size of it's original components; usually it comes from shales, sedementary rock with clay minerals that after metamorphism sometimes become micas.

Coral polyp colonies, often known as coral reefs, number in the hundreds to thousands. These sessile (fixed in one spot permanently) marine invertebrate creatures have strong calcium carbonate exoskeletons.

What role do corals play in marine ecosystems?

Coral reefs offer chances for recreation, serve as a barrier against erosion and storm damage, and support local economies. They are also a source of fresh medications and food. More than 500 million people rely on reefs for safety, income, and food.

What is the coral reef ecosystem made of?

Thin calcium carbonate layers make up a coral reef.

Over a skeleton made of calcium carbonate, coral polyps create a living carpet. The corals most in charge of creating the groundwork for and erecting reef structures are known as stony corals (or scleractinians).

How are coral reefs formed ?

When free-swimming coral larvae cling to submerged rocks or other hard surfaces along the margins of islands or continents, coral reefs are first formed. Reefs develop one of three main structural types as the corals swell and grow: fringing, barrier, or atoll.

The reason why geography does not haveunique definition and consensus among Geographers is because:

• It is too broad.

Geography is the study of everything that is on the surface of the earth and they can be classified into:

• Human Geography
• Regional Geography
• Physical Geography,  etc,

Therefore, the main reason why it does not have a unique definition is because it is so broad and covers a lot of areas and it cannot possibly have one unique definition because it does not do it enough justice.

Because geography is such a large and all-encompassing discipline, as you can see from the definitions, it is difficult to define. It is much more than just studying maps and physical elements of the land since humans are impacted by and influence the land.
