Question

Find 3 interesting facts about our planet

Answer 1

1. Plate Tectonics Keep the Planet Comfortable:

Earth is the only planet in the Solar System with plate tectonics. Basically, the outer crust of the Earth is broken up into regions known as tectonic plates. These are floating on top of the magma interior of the Earth and can move against one another. When two plates collide, one plate will subduct (go underneath another), and where they pull apart, they will allow fresh crust to form. 2. Earth is Almost a Sphere:

Many people tend to think that the Earth is a sphere. In fact, between the 6th cenury BCE and the modern era, this remained the scientific consensus. But thanks to modern astronomy and space travel, scientists have since come to understand that the Earth is actually shaped like a flattened sphere (aka. an oblate spheroid).

This shape is similar to a sphere, but where the poles are flattened and the equator bulges. In the case of the Earth, this bulge is due to our planet’s rotation. This means that the measurement from pole to pole is about 43 km less than the diameter of Earth across the equator. Even though the tallest mountain on Earth is Mount Everest, the feature that’s furthest from the center of the Earth is actually Mount Chimborazo in Ecuador.

Answer 2

Sure, here are three interesting facts about our planet:

1. Earth is the only planet known to have liquid water on its surface, which is essential for life as we know it. Approximately 71% of the Earth's surface is covered by water, with the remaining 29% consisting of landmasses.

2. The Earth's magnetic field, also known as the magnetosphere, protects us from the harmful effects of the solar wind. The solar wind is a stream of charged particles released by the sun, and without the magnetosphere, these particles could strip away the Earth's atmosphere and make it uninhabitable.

3. The Earth's rotation is gradually slowing down, which means that our days are getting longer. The rotation of the Earth is affected by various factors, including the gravitational pull of the Moon and the tides it creates, as well as the movement of tectonic plates. Over the last 2,700 years, the length of a day has increased by approximately 2.3 milliseconds.
