This exploration of Planet Earth is concerned with how science sees, measures, and senses the unknown. We can’t go to the stars, but we know their chemical composition. We can’t drill to the center of the Earth, but we know its density. Figure 1-1. Contrast the surface of Earth to that of Europa, a moon of Jupiter, that is the only other object

Compare and contrast planets in terms of: size relative to earth; surface and atmospheric features; relative distance from the sun; ability to support life. S6E1e. Explain that gravity is the force that governs the motion of the solar system. Use the Solar System Planet Notes to record important information.

high-flying airplanes with their radiation! Space weather affects not only Earth but the other planets as well. Our Eye on the Sky – Launched in February 2010, NASA’s Solar Dynamics Observatory (SDO) mission is designed to study the Sun’s variability and its effect on space weather, with the goal of eventually predicting dangerous

Some planets, like Earth, Mercury, Jupiter and Saturn, have magnetic fields created by their iron core. The magnetic field that protects Earth extends from the inner core out to where it meets charged particles coming from the Sun, also known as solar wind. The magnetic field shields the atmosphere from the high- energy particles coming from space.

Landscape: Earth’s crust is made up of shifting tectonic plates that move over a thick, rocky mantle. 75% of it is covered with water. It is tilted on its axis creating seasons. It has active volcanoes and is the only planet with life. It’s atmosphere is made up of nitrogen and oxygen. The range of temperatures around the planet average 57.2°F

Earth (Figure 1) is one of nine planets orbiting around a 4.5 billion year old medium-sized star we call the Sun. It takes 365.26 days to make one rotation, while spinning on its axis once every 23.93 hours. Earth’s orbit lies almost 149.59 million kilometers (or 1 astronomical unit, AU) from the Sun in between those of Venus and Mars. Together

Earth’s geologic development with its strong climatic variations. This book presents the current state of research on our planet’s evolution and structure. It seeks to elucidate the complex inter-connections of contemporary concepts and ideas in earth sciences, which are the basis for a better understanding of present-day developments on ...

Planets: Eight planets orbit the sun, classified into two main groups: o Inner planets: Mercury, Venus, Earth, and Mars (rocky planets) o Outer planets: Jupiter, Saturn, Uranus, and Neptune (gas giants)

planets are solid and rocky like Earth (terra means “earth” in Latin). The four planets that are more distant from the sun—Jupiter, Saturn, Uranus, and Neptune—are called gas giants.
