Question

Chapter 11, Problem 1RQ

To determine

The reason for the rocks that are present on the earth could not yield isotopic dates older than 4 billion years.

Expert Solution & Answer

Answer to Problem 1RQ

The rocks on the earth could not yield isotopic dates older than 4 billion years because, they might have undergone melting or metamorphic chemical reactions due to high pressure and temperature or erosional effects. It is also stated by the astronomers that the heavy bombardment of meteorites during 4.1 Ga to 3.8 Ga have melted and pulverized the rocks that are present on the earth.

Explanation of Solution

The rocks present on the surface of the earth are classified into three types based on their mode of formation: igneous, sedimentary and metamorphic rocks. Isotopic dating is the process of finding the age of the rocks by using the isotopic minerals that are present in the rocks.

By the isotopic dating of meteorites, the age of the earth is calculated as 4.54 Ga. But, the oldest rock on the surface of the earth are dated only 4.0 Ga. This calculated time between 4.0 Ga-4.54 Ga is termed as Haden Eon. The rocks between this period left no mark in the history. The rocks are formed either by the cooling of magma and lava or by the erosion, deposition and compaction of sediments or by the chemical reactions that caused due to high temperature and pressure.

In this course, we examine how social, economic, political and cultural processes transform relationships between people and the spaces they inhabit. Globalization is one of the key processes shaping human geographies in the 21st century. Although globalization operates at a planetary scale, its effects are felt in the spaces and routines of daily life. For this assignment, you are asked you to observe and analyze how globalization manifests in your own everyday experiences. Objectives • • Apply core geographic concepts of place, space and scale • Identify concrete examples of how global processes shape local contexts • Develop skills in observation and analysis Instructions 1. Choose two aspects of daily life from the following list that you will use to explore the influences of globalization: ○ Material goods - commodities, food ○ Media & entertainment о Technology & communication о Social connections and relationships O Linguistic or cultural landscapes 2. For each aspect, identify…

Write an opening statement and a brief background for this discussion: efforts should be made to create distance and separate crops that produce pollutants such as ecoli (i.e. animal farming) from crops that don’t (i.e. lettuce) to protect these latter crops despite the extra costs and logistical challenges.
