- Question 1 of 5
1. Question
1 pointsConsider the following statements regarding ‘Lithosphere’
1) The upper part of lithosphere consists of basaltic rocks and farms the continents.
2) The lower part of lithosphere is a continuous zone of granitic rocks forming the ocean floors.
Which of the above statement(s) is/are correct?Correct• The upper part consists of granitic rocks and farms continents and its mineral constituents are sial (Silica + Aluminia)
• The lower part is a continuous zone of denser basaltic rocks farming the ocean floors, comprising mainly silica, iron and magnesium (Sima).Incorrect• The upper part consists of granitic rocks and farms continents and its mineral constituents are sial (Silica + Aluminia)
• The lower part is a continuous zone of denser basaltic rocks farming the ocean floors, comprising mainly silica, iron and magnesium (Sima). - Question 2 of 5
2. Question
1 pointsConsider the following statement related to ‘Core’ of the earth.
1) It is made up of mainly iron (fe) and some nickel.
2) It is subjected to extremely high pressure.
3) It is present in the liquid form.
Which of the above statement(s) is/are correct?Correct(1) Core is made up of iron (major part) and nickel (minor part).
(2) Core is subjected to extremely high pressure and under such conditions, they are could be expected to be in a liquid state but various studies through earthquake wave have suggested that the innermost part of core is a crystalline or solid mass.Incorrect(1) Core is made up of iron (major part) and nickel (minor part).
(2) Core is subjected to extremely high pressure and under such conditions, they are could be expected to be in a liquid state but various studies through earthquake wave have suggested that the innermost part of core is a crystalline or solid mass. - Question 3 of 5
3. Question
1 pointsConsider the following statement related to ‘Igneous rocks’ when divided on the basis of mineral composition.
1) Igneous rock that contains a low proportion of silica is said to be acidic.
2) Igneous rock the contains a high proportion of silica is said to be basic.
Which of the following statement(s) is/are correct?Correct(1) When Igneous rocks contain a high proportion of silica they are said as acidic. These rocks are less dense and lighter in colour.
(2) On the other hand when Igneous rocks contain a low proportion of silica they are said as basic. These rocks are denser and darker in colour.Incorrect(1) When Igneous rocks contain a high proportion of silica they are said as acidic. These rocks are less dense and lighter in colour.
(2) On the other hand when Igneous rocks contain a low proportion of silica they are said as basic. These rocks are denser and darker in colour. - Question 4 of 5
4. Question
1 pointsWhich of the following is not a Sedimentary Rock?
Correct- Slate is a metamorphic rock and clay is metamorphosed into slate.
Incorrect- Slate is a metamorphic rock and clay is metamorphosed into slate.
- Question 5 of 5
5. Question
1 pointsConsider the following statement related to ‘block mountains’
(1) These mountains came to existence when faulting takes place in earth’s crust
(2) Block mountains can be generation due o both tensions and compressional forces in the crust.
3) The east African rift valley system is a example of block mountains.
Which of the above statement(s) is/are correct:-Correct(1) Block mountain a type of mountains comes to existence due to cracks i.e. faulting of earth’s crust.
(2) Block mountains can be result of either tension force or compression forces and mostly rift valley is farmed by compression when fault develops.
(3) The east Africa rift valley system stretching from east Africa to Syria is example of Block mountains.Incorrect(1) Block mountain a type of mountains comes to existence due to cracks i.e. faulting of earth’s crust.
(2) Block mountains can be result of either tension force or compression forces and mostly rift valley is farmed by compression when fault develops.
(3) The east Africa rift valley system stretching from east Africa to Syria is example of Block mountains.
