Answer:  

1.) 'The temperature and pressure' in the 'subpolar and polar zone' are very close to the Solidification for WATER'.

2.) 'Geosystem regions' are the only 'climate regions where 'water can exist in a 'gas, liquid, or solid'.

3.) 'Each climate zone' has 'different weather patterns' due to 'different amounts of Exposure' that reach Earth in each zone'.

4.) 'The most popular system for 'classifying climate' in 'different regions on Earth' is 'The Koppen Climate Classification System'.

5.) The data scientist USES direct measurements like the ENTIRE history of earth's climate to indirect measurements like recent satellite observations analyze climate. They USE this data to compare the climatic conditions in the past with the present.

Explanation:

• The temperature is subzero in the polar and subpolar regions, and the pressure is very high and this leads water to exist in its solidified state in these geographical regions.
• Geosystems are the only regions on the planet that ALLOWS water to exist in all the three forms.
• Exposure determines the climatic pattern of different types.
• The system of Koppen Climate classification is the most widely used system of differentiating and typifying climate.
