Earth science

Earth science or geoscience is an all-encompassing term that refers to the fields of science dealing with planet Earth. It can be considered to be a branch of planetary science, but with a much older history. There are both reductionist and holistic approaches to Earth sciences. The formal discipline of Earth sciences may include the study of the atmosphere, hydrosphere, lithosphere, and biosphere. Typically, Earth scientists will use tools from physics, chemistry, biology, chronology, and mathematics to build a quantitative understanding of how the Earth system works, and how it evolved to its current state.

Fields of study

The following fields of science are generally categorized within the Earth sciences:

Earth

Earth /ˈɜːrθ/ (also the world, in Greek: Γαῖα Gaia, or in Latin: Terra) is the third planet from the Sun, the densest planet in the Solar System, the largest of the Solar System's four terrestrial planets, and the only astronomical object known to harbor life.

According to evidence from radiometric dating and other sources, Earth was formed about 4.54 billion years ago. Earth gravitationally interacts with other objects in space, especially the Sun and the Moon. During one orbit around the Sun, Earth rotates about its own axis 366.26 times, creating 365.26 solar days or one sidereal year. Earth's axis of rotation is tilted 23.4° away from the perpendicular of its orbital plane, producing seasonal variations on the planet's surface with a period of one tropical year (365.24 solar days). The Moon is Earth's only permanent natural satellite. Its gravitational interaction with Earth causes ocean tides, stabilizes the orientation of Earth's rotational axis, and gradually slows Earth's rotational rate.

The Good Earth

The Good Earth is a novel by Pearl S. Buck published in 1931 and awarded the Pulitzer Prize for the Novel in 1932. The best-selling novel in the United States in both 1931 and 1932 was an influential factor in Buck's winning the Nobel Prize for Literature in 1938. It is the first book in a trilogy that includes Sons (1932) and A House Divided (1935).

The novel, which dramatizes family life in a Chinese village before World War I, has been a steady favorite ever since. It was included in Life Magazine's list of the 100 outstanding books of 1924–1944. In 2004, the book was returned to the bestseller list when chosen by the television host Oprah Winfrey for Oprah's Book Club. The novel helped prepare Americans of the 1930s to consider Chinese as allies in the coming war with Japan.

A Broadway stage adaptation was produced by the Theatre Guild in 1932, written by the father and son playwriting team of Owen and Donald Davis, but it was poorly received by the critics, and ran only 56 performances. However, the 1937 film, The Good Earth, which was based on the stage version, was more successful.
