• Question 1 of 5 1. Question Consider the following statements. Earth’s crust has a density higher than the mantle part of Earth. The inner core of the Earth is in solid state. Which of the above statements is/are correct? a) 1 only b) 2 only c) Both 1 and 2 d) Neither 1 nor 2 Correct Solution: B The portion of the interior beyond the crust is called the mantle. It has a density higher than the crust’s (3.4 g/cm3). The outer core of Earth is in liquid state while the inner core is in solid state. The core is made up of very heavy material mostly constituted by nickel and iron. It is sometimes referred to as the nife layer.

#### 1. Question

Consider the following statements.

• Earth’s crust has a density higher than the mantle part of Earth.

• The inner core of the Earth is in solid state.

Which of the above statements is/are correct?

• c) Both 1 and 2

• d) Neither 1 nor 2

• Question 2 of 5 2. Question Consider the following statements regarding Karst topography. It is commonly associated with carbonate rocks. Such topography occurs only in tropical and temperate environments. Nearly a quarter of the world’s population depends upon water supplied from karst areas. How many of the above statements is/are incorrect? (a) Only one (b) Only two (c) All three (d) None Correct Solution: A Statement 2 is incorrect. The term karst describes a distinctive topography that indicates dissolution (also called chemical solution) of underlying soluble rocks by surface water or ground water. Although commonly associated with carbonate rocks (limestone and dolomite) other highly soluble rocks such as evaporates (gypsum and rock salt) can be sculpted into karst terrain. Understanding caves and karst is important because ten percent of the Earth’s surface is occupied by karst landscape and as much as a quarter of the world’s population depends upon water supplied from karst areas. Though most abundant in humid regions where carbonate rock is present, karst terrain occurs in temperate, tropical, alpine and polar environments. Incorrect Solution: A Statement 2 is incorrect.

• Question 3 of 5 3. Question Consider the following statements regarding Badland Topography. Presence of Hard archaic granite rock system. Characterized by steep slopes and minimal vegetation. The geologic forms of Canyons, ravines, gullies, buttes and mesas are common in badlands. How many of the above statements is/are incorrect? (a) Only one (b) Only two c) All three d) None Correct Solution: A Statement 1 is incorrect. Badlands are a type of dry terrain where softer sedimentary rocks and clay-rich soils have been extensively eroded by wind and water. They are characterized by steep slopes, minimal vegetation, lack of a substantial regolith, and high drainage density. They can resemble malpaís, a terrain of volcanic rock. Canyons, ravines, gullies, buttes, mesas, hoodoos and other such geologic forms are common in badlands. Incorrect Solution: A Statement 1 is incorrect.

• Question 4 of 5 4. Question Consider the following statements. Moraines are accumulations of dirt and rocks that have fallen onto the glacier surface or have been pushed along by the glacier as it moves. Loess is a type of silt which forms fertile topsoil in some parts of the world. Which of the above statements is/are correct? a) 1 only b) 2 only c) Both 1 and 2 d) Neither 1 nor 2 Correct Solution: C Moraines are accumulations of dirt and rocks that have fallen onto the glacier surface or have been pushed along by the glacier as it moves. The dirt and rocks composing moraines can range in size from powdery silt to large rocks and boulders. A receding glacier can leave behind moraines that are visible long after the glacier retreats. Loess consists of tiny mineral particles brought by wind to the places where they now lie. It is a product of past glacial activity in an area. It is a sedimentary deposit of mineral particles which are finer than sand but coarser than dust or clay, deposited by the wind.
