(b) Only two
Glaciers are a bulk of ice moving under its weight. It forms in areas where the amassing of snow goes beyond its ablation over many years. They are sensitive indicators of changing climate.
Out of total water on Earth, 2.1% is in glaciers while 97.2% is in the oceans and inland seas.
Glacier can be categorized as Mountain Glacier (Alpine Glaciers) or Continental Glacier (Ice Sheets). (Statement 1 is correct)
The Continental Glacier moves outward in all directions whereas the Mountain Glacier moves from a higher to a lower altitude. (Statement 2 is incorrect).
The continental glaciers are the largest ice sheets and cover most of Antarctica and islands of Greenland. (Statement 3 is correct)

(b) Health Service
‘Kilkari’ (meaning ‘a baby’s gurgle’), is a centralized interactive voice response (IVR) based mobile health service.
It delivers free, weekly, time-appropriate 72 audio messages about pregnancy, childbirth, and childcare directly to families’ mobile phones from the second trimester of pregnancy until the child is one year old.
Women who are registered in Reproductive Child Health (RCH) portal based on the woman’s LMP (last menstrual period) or the child’s DoB (Date of Birth), receive a weekly call with pre-recorded audio content directly to the mobile phones of pregnant women and mothers with children under the age of one year.
Kilkari audio messages are present in the form of the voice of a fictitious doctor character called Dr. Anita.
It is centrally hosted by the Ministry of Health and Family Welfare (MoHFW) for all the States/UTs and no further investment in the technology, telephony infrastructure or operational costs is required to be borne by States/UTs.

(a) Mercury
Cinnabar is an ore of Mercury (Hg) and its atomic number is 80. Cinnabar is the ore from which mercury is extracted. Mercury is obtained by heating Cinnabar in excess of air and condensing it giving it mercury vapour. Due to the low boiling point of mercury, it is easily purified by using vacuum distillation.

(a) Petroleum is referred to as “Black Gold.” Crude oil is taken into account to be the “mother of all commodities” because it is employed to manufacture various products like pharmaceuticals, plastics, gasoline, synthetic fabrics, etc.
Petroleum or oil has also been the world’s leading source of energy since the 1950s. When it’s drilled from the bottom within the liquid form, it’s called petroleum. Petroleum is made from the remains of dead plants and animals.
Certain bacteria helped within the decomposition of this organic matter and caused some chemical changes. Matter consisting of largely carbon and hydrogen (Hydrocarbon) was left behind. However, as there’s not sufficient oxygen at the rock bottom of the ocean, the matter couldn’t decompose completely.
The grade of petroleum depends mainly on the relative proportion of the different hydrocarbons, and other factors such as its specific gravity or API and its sulphur content—and its location—for example, its proximity to tidewater and/or refineries.
India’s strategic crude oil storages are currently located at Visakhapatnam (Andhra Pradesh), Mangaluru (Karnataka), and Padur (Karnataka).
The government has also given approval for setting up of two additional facilities at Chandikhol (Odisha) and Padur (Karnataka).

(d) Toiletries
Triclosan is an antibacterial chemical having a lipophilic structure. It’s a bacterial reduction or prevention component found in a variety of consumer items. It is found in antibacterial soaps, body washes, toothpaste, cosmetics, etc.
