Imagine you are a farmer, owns a farmland which is infertile. How would you convert it into fertile farmland?​

Answer:

A galaxy is a collection of stars and interstellar material held together by gravity. The galaxy our Sun lives in is called the Milky Way.

The name `Milky Way' comes from the band of light that is seen overhead on very dark nights.

A thick layer of interstellar dust hides much of the Galaxy from observation by optical telescopes, and astronomers can determine its large-scale structure only with the aid of radio and infrared telescopes, which can detect the forms of radiation that penetrate the hidden matter.

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.

Answer:

3. climographs

Explanation:

• The climograph is a graphical representation of the climatic features such as the rainfall pattern and the temperature and the amount of the data is used for comparison of the yearly and monthly basis and has two or more variables are used to depict the differences.

• Useful to understand the world climatic patterns of different regions in the world. They have wide application s are used in the military and time of the natural events.  

• By showing temperature, pressure and the rainfall and cloud and the humidity pattern found in a particular place they are a valuable tool if info for the modern-day weather.
