Earth's surface is the boundary between the atmosphere, and the solid Earth and oceans. Defined in this way, Earth's shape is an idealized spheroid – a squashed sphere – with a surface area of about 510 million square km (197 million sq mi).

(D) 4 °C
(D) 4 °C
Answer: (D) 4 °C
Answer: (D) 4 °C
Answer: (D) 4 °C
Water has its maximum density at 4° Celsius (39.2° Fahrenheit), in its liquid phase. At this temperature, water's density is 0.9998395 grams per milliliter (g/ml). This is slightly less than 1 g/ml.
Water behaves abnormally at this temperature. When water is heated from 0° Celsius, its volume decreases until it reaches 4° Celsius. Above 4° Celsius, water's volume increases as the temperature increases. At 4° Celsius, the cage-like structure of water begins to break and come closer, which decreases the volume and increases the density. Water's solid phase, ice, is more buoyant and forms at the surface of bodies of water, where it freezes downward.

Answer: (A) Seismic
Answer: (A) Seismic
Answer: (A) Seismic
The Earth's crust is not a single, unbroken shell; it's divided into large pieces called tectonic plates. The boundaries where these plates meet are subject to immense stress due to their constant movement. These areas, characterized by frequent movement and deformation, are known as seismic zones or fault zones. The accumulated stress in these weak zones is eventually released in the form of earthquakes. While the asthenosphere is a weak, semi-fluid layer beneath the lithosphere (which includes the crust), the term "seismic zone" specifically refers to the regions within the crust that are prone to seismic activity.

Answer: (A) Palaeontology
Answer: (A) Palaeontology
Paleontology is the scientific study of fossils, which are the remains of plants, animals, fungi, bacteria, and single-celled living things that have been replaced by rock material or impressions of organisms preserved in rock. Fossils can be shells, bones, or plant leaves, which are called body fossils. Trace fossils are preserved tracks, trails, and burrows that record an organism's life activities.
