Do you know how the aurora? Explanation of how the aurora described by Explanation Text. Here we go!

Definition and Purpose of Explanation Text 

Generally the purpose of an explanation text is explaining how something forms or why the thing happens. So when we read an explanation text, the text will cover the answer of "how" or "why" relating to a thing or a phenomenon. An explanation text is organized with the generic structure of a general statement and a sequence of explanations. 

Generic structure of Explanation

General statement :  stating the phenomenon issues which are to be explained.

Sequenced explanation : stating a series of steps which explain the phenomena.

Language Feature of Explanation

Featuring generic participant; sun, rain, etc.

Using chronological connection; to begin with, next, etc

Using passive voice pattern.

Using simple present tense.

Here is an example of Explanation Text

AURORA

An aurora (plural aurorae/auroras) is an electro-static phenomenon, characterized by a bright glow and caused by the collision of charged particles in the magnetosphere with atoms in the Earth’s upper atmosphere.
Ultimately, the source lies in the solar wind, a fast-moving stream of particles constantly flowing from the Sun that carries the Sun’s magnetic field out into space. The solar wind, typically moving at 250 miles (400 kilometers) per second, flows past Earth’s magnetic field and molds it into an elongated bubble or cavity, compressing its sun ward side and stretching its night side far beyond the Moon’s orbit. Under certain conditions, the solar wind’s magnetic field can merge with Earth’s, creating electrical currents that drive protons and electrons into the polar atmosphere. Powerful events occurring on the Sun can drive enormous changes in the solar wind, increasing both its speed and density and enhancing its effect on Earth.

An aurora is usually observed in the night sky, particularly in the polar zone. For this latter reason, some scientists call it a “polar aurora” (or “aurora Polaris”). 

Aurora Colored light in the night sky near the Earth’s magnetic poles, called aurora borealis (‘northern lights’) in the northern hemisphere and aurora australis (‘southern lights’) in the southern hemisphere. 

Northern lights is the name of a light phenomenon often seen in the northern regions. The lights have been around since Earth formed an atmosphere The scientific name for the phenomenon is “Aurora Borealis”, aurora for short.

The southern lights or aurora australis, most commonly seen in southern New Zealand. It shows a typical red and green aurora, the nearly vertical rays tracing the earth’s magnetic field lines.
