The Earth Is a Mystery

Happy Earth Day!

Earth is the third planet from the sun and the fifth largest in the solar system. The earth is a big mystery. It is the only planet that has oxygen, gravity, and constant movement. The Earth consists of four concentric layers: inner core, outer core, mantle and crust. The crust is made up of tectonic plates, which are in constant motion. Earthquakes and volcanoes are most likely to occur at plate boundaries. The crust is the land and ocean where we live.

One of the best places to observe the volcanic activities is Yellowstone National Park.

Yellowstone National Park spans an area of 3,468.4 square miles (8,983 sq. km), comprising lakes, canyons, rivers and mountain ranges. Mostly in Wyoming, the park spreads into parts of Montana and Idaho. Yellowstone Lake is one of the largest high-elevation lakes in North America and is centered over the Yellowstone Caldera, the largest supervolcano on the continent. The Caldera is considered an active volcano. It has erupted with tremendous force several times in the last two million years. Half of the world’s geothermal features are in Yellowstone, fueled by this ongoing volcanism. Lava flows and rocks from volcanic eruptions cover most of the land area of Yellowstone. Yellowstone features dramatic canyons, alpine rivers, lush forests, hot springs and gushing geysers, including its most famous, Old Faithful. The park is the centerpiece of the Greater Yellowstone Ecosystem, the largest remaining nearly-intact ecosystem in the Earth’s northern temperate zone.
