पुढील दोन विधानांचा विचार करा. / Consider the following two statements :

(a)दोन्ही अर्ध्यागोलात 10° ते 20° अक्षांशत वाळवंट आहेत / There are deserts between 10° and 20° latitudes in both the hemispheres

(b)10° ते 20° अक्षांशत पावसापेक्षा बाष्पेचे प्रमाण अधिक आहे / Between 10° and 20° latitudes evaporation exceeds precipitation

1)दोन्ही (A) व (B) खरे आहेत व (B) हे (A) चे कारण आहे / Both (A) and (B) are true and (B) is the reason for (A)
2)दोन्ही (A) व (B) खरे आहेत परंतु (B) हे (A) चे कारण नाही / Both (A) and (B) are true but (B) is not the reason for (A)
3)केवळ (A) खरे आहे / Only (A) is true
4)केवळ (B) खरे आहे / Only (B) is true✓ Correct

Deserts are typically found in the subtropical high-pressure belts (10° to 30° latitudes) where descending air causes high atmospheric stability and dryness. In these regions, high temperatures lead to high evaporation rates which vastly exceed precipitation, resulting in arid conditions.

दिलेल्या उताऱ्यावरून आपणास ला निना बद्दल काय माहिती मिळते ? / What information do we get about La Nina from the given paragraph ?

(a)हा थंड सागरी प्रवाह आहे. / It is a cold ocean current.

(b)हा एल निनोच्या विरुद्ध आहे. / It is opposite to El Nino.

(c)ला निना ही एल निनोची धाकटी बहीण मानली जाते. / The La Nina is considered to be the younger sister of El Nino.

(d)ला निना तयार झाल्यानंतर व्यापारी वारे त्यांचा वेग वाढवतात. / After the occurrence of La Nina, trade winds increase their speed.

1)फक्त (a) आणि (b) / Only (a) and (b)
2)फक्त (c) / Only (c)
3)फक्त (a), (b) आणि (c) / Only (a), (b) and (c)
4)(a), (b), (c) आणि (d) / (a), (b), (c) and (d)✓ Correct

La Nina is characterized as a cold ocean current, opposite to El Nino, often called its younger sister, which strengthens trade winds.
