Earth

1.) Basic Statistics

• A.) Terrestrial Planet whose surface is divided into tectonic plates
• B.) 92,955,807 miles from the sun
• C.) Between Venus and Mars
• D.) 365.3 days to do revolution
• E.) 23hrs and 56min to do a rotation

1.) Basic Statistcis

• F.) How it orbits at 0.7(red ellipse), 1.3(blue outer line)
• G.) 7,926 miles is the diameter
• H.) -89 C to 58 C is the surface temperature
• I.) 100% of Earths Gravity
• J.) 1 Satellite

Physical Properties of Earth

• 1.) Crust
• 2.) Molten Outer Core
• 3.) Inner Core

Greenhouse Effect: How it affects temperature

• Greenhouse Effect: Warming of the Earths atmosphere
• It affects the Earths average temperature by warming the surface
• Plus the air around the Earth

Earth Completely Solid inside?

• No, because the different layers of Earth are solid and liquid
• The scientist can tell because they send seismic waves

Possible for entire continents to move?

• Yes, because of the Alfred Wegner theroy
• Like how Africa and Europe split a part during the Pangea

Magnetic Field Protects Life?

• The magnetic field protects life on Earth from dangerous particles
• that float around outer space.

WHAT MAKES EARTH UNIQUE?

• It is the only planet in the solar system that has life on it
• with living people and plants. Plus it is the planet with an oxygen rich air

Global Warming & Ozone Hole Concerning

• Global Warming:a gradual increase in the overall temperature of the earth's atmosphere generally attributed
• to the greenhouse effect caused by increased levels
• of carbon dioxide, chlorofluorocarbons, and other pollutants.
• We should also be concerned because it is warming our ocean which makes the weather severe and
• mess with the food for the people and for the animals

Fun Facts on Earth

• Age: 4.54 billion years old
• The Earth is slightly flattened at the North and South poles
• Earth has a powerful magnetic field: protecting us from solar wind
• Earth has the greatest density at 5.52 grams per cubic cm
• 70% of the Earth is covered by water
