खालील पैकी कोणता घटक प्रवाल किटकांच्या वाढीला कारणीभूत आहे? Which of the following factor is responsible for low coral growth?
Upwelling brings cold, nutrient-rich deep water to the surface, which lowers temperatures and introduces excess nutrients/turbidity that hinder coral growth.
खाली दोन विधाने आहेत. त्यापैकी (अ) हे विधान असून (र) हे त्याचे कारण आहे खालील दिलेल्या पर्यायांपैकी योग्य पर्याय निवडा. विधान (अ) : विषुववृत्तीय प्रदेशामध्ये सागराची क्षारता कमी असते. कारण (र) : विषुववृत्तीय प्रदेश हा अति पर्जन्यमान, आभाच्छादित आकाश आणि आर्द्रता ही वैशिष्ट्ये असलेला आहे. Given below are two statements, one labelled as Assertion (A) and the other labelled as Reason (R). Select your answer from the following options. Assertion (A) : Oceanic salinity is low in the equatorial region. Reason (R) : Equatorial region is characterized by heavy rainfall, cloudiness and humidity.
High rainfall in the equatorial region brings freshwater, which dilutes the ocean water and lowers its salinity, making both the assertion and reason true and properly linked.
खालील विधानांचा विचार करून बिनचूक पर्यायांची निवड करा. अ. ज्या ठिकाणी खंडांत उतार अतिशय रुंद असतो, त्या क्षेत्रामध्ये मत्स्य क्षेत्रे तयार होतात. ब. उबदार उष्णकनटीबंधीय सागरी पाण्यामध्ये मासेमरी विकसित झालेली आहे. क. उष्ण आणि थंड समुद्र प्रवाहांच्या मिश्रमधून माशांसाठी वनस्पती खाद्य आणले जाते. ड. भारतामध्ये अंतर्गत मासेमरी इतर मासेमारी प्रकारापेक्षा अधिक महत्त्वाची आहे.
(a)Most of the fishing grounds occur in areas where the continental shelf is wide.
(b)Fishing activity is well developed in warm tropical waters.
(c)Mixing of warm and cold currents brings plant nutrients for fish.
(d)Inland fisheries are more significant than other types in India.
Statements A, B, and C are correct: wide continental shelves create rich fishing grounds, tropical waters and current mixing support fisheries. Statement D is false because marine fisheries generally account for a larger share than inland fisheries in India historically (though inland is growing).
