Answer 2

The following are suggested answers to the review questions at the end of chapters in Physical Geology. Answers to the exercises are provided in Appendix 3.

Chapter 1

Geology involves integration of various different sciences (chemistry, physics, and biology for example), but also requires an understanding of the importance of billions of years of geological time.

Paleontology is an important aspect of geology and requires an understanding of biology, including evolution, the physiology of animals and plants and ecological relationships.

Geologists provide information to reduce the risk of harm from hazards such as earthquakes, volcanoes, and slope failures; they play a critical role in the discovery of important resources; they contribute to our understanding of life and its evolution through paleontological studies; and they play a leading role in the investigation of climate change, past and present and its implications.

Halite is composed of sodium (Na) and chlorine (Cl) with the Na+ and Cl− ions alternating with one another in all three directions within a cubic structure.

A mineral has a specific chemical composition and lattice structure. Rocks are made out of minerals, and most rocks contain several different types of minerals.

The main component of Earth’s core is iron (Fe).

Transfer of heat from the core to the mantle leads to heating of lower mantle rock. When heated, the rock expands and its density is reduced. Because the mantle is plastic, this lower-density material tends to rise toward the surface, and cooler denser mantle material moves in to take its place.

Mantle convection creates the traction that can force plates to move around on the surface.

Hot mantle rock moving toward the surface partially melts because the pressure is reduced. The magma produced moves upward into cracks in the crust and is extruded onto the sea floor.

215 − 65 = 150 Ma. Since the age of the Earth is 4570 Ma, this represents 150 ÷ 4,570 = 0.033 or 3.3% of geological time.

At 1 mm/y, 30,000,000 mm would accumulate over that 30 million years. This is equivalent to 30,000 metres or 30 kilomet please mark as brainliest
