Formation of the Solar System

• The nebular theory is about how the solar system formed.
• Made from 98% helium and hydrogen• 2% of other elements also helped create
the solar system.• Earth and other terrestrial worlds were
made from the other heavier elements.• The motion the planets orbit in was caused
by gravity, heating, spinning, and flattening.
• Began as a spherical cloud of cold and low-density gas.
Terrestrial Planets’ Geology & Atmosphere
• Internal heat, primarily from radioactive decay can cause volcanic and tectonic activity.
• Only large planets retain enough internal heat to stay geologically active today.

• Named after the Roman God of Commerce, Mercury
• One of the most notable features of its geography is the
Caloris Basin
• Sun-scorched surface
• Only slightly larger than the Earth’s Moon
• Has very little atmosphere and is covered in craters
• Temperatures can range from 800 degrees Fahrenheit to -290
degrees Fahrenheit
• 2nd Most Dense Planet after Earth
• Large Metallic Core

• 2nd Planet From the Sun
• Closest Planet to Earth
• Brightest Object in the Sky
other the Sun and Moon
• Surface covered with
craters, volcanoes,
mountains and large plains
of lava
• Atmosphere is mainly
carbon dioxide
• Clouds are sulfuric acid
• One of the hottest planets
in the Solar System
• Rotates backwards

• Cold Desert World
• Half the Diameter of Earth
• Has seasons, polar ice caps, volcanoes, canyons, and
weather
• Atmosphere too thin for water to exist in liquid form for any
length of time
• Signs indicate ancient floods
• No magnetic field around the globe
• Has two moons: Phobos and Deimos
• Near-Earth Objects (NEOs) are comets and asteroids that have been nudged by the gravitational attraction of nearby planets into orbits that allow them to enter the Earth's neighborhood. (NASA, 2013)
