When I was a child I use to say; “Let us share our food with the Earth so that Earth wouldn’t get angry and sink down with us” Little did I know that there was a day set aside to celebrate what sustains our lives, The Earth.
The fifth-largest planet of the solar system and the third in order of position from the sun. It is an oblate spheroid, being slightly flattened at the poles. Satellite observations have indicated other slight irregularities in the shape of the earth. Its mass is approximately 5.98 × 1024 kg (13.18 × 1024 lb). Its area is about 510,000,000 sq km (197,000,000 sq mi). Earth’s measurements are (approximately): circumference at the equator, just over 40,000 km (24,900 mi); diameter at the equator, 12,750 km (7,920 mi). Oceans and seas cover approximately 71 percent of its surface, leaving about 149,000,000 sq km (57,500,000 sq mi) of land surface.
The earth rotates on its axis, bringing about day and night. (Ge 1:4, 5) A solar day or an apparent day is a period of 24 hours, the time taken for an observer at any one point on the earth to be again in the same position relative to the sun. The tropical year, which concerns the return of the seasons, the interval between two consecutive returns of the sun to the vernal equinox, is 365 days, 5 hours, 48 minutes, and 46 seconds, on the average. This figure is the one used in solar-year calendar reckoning, and its fractional nature has caused much difficulty in accurate calendar making.
The axis of the earth tilts 23° 27ʹ away from a perpendicular to the earth’s orbit. The gyroscopic effect of rotation holds the earth’s axis in basically the same direction relative to the stars regardless of its location in its orbit around the sun. This tilt of the axis brings about the seasons.
The earth’s atmosphere, composed principally of nitrogen, oxygen, water vapor, and other gases, extends over 960 km (600 mi) above the earth’s surface. Beyond this is what is termed “outer space.”
Earth Day 2017’s Campaign is Environmental & Climate Literacy
Education is the foundation for progress. We need to build a global citizenry fluent in the concepts of climate change and aware of its unprecedented threat to our planet. We need to empower everyone with the knowledge to inspire action in defense of environmental protection.
Environmental and climate literacy is the engine not only for creating green voters and advancing environmental and climate laws and policies but also for accelerating green technologies and jobs.
This Earth Day, gather with your community for an Environmental & Climate Literacy Teach-In or another project focused on education. We are launching Earth Day and Teach-In toolkits that will lay out the steps for holding a successful event. Register your event with us and we will support you with promotion and advice.
