Can you help me outline an essay introduction about earthquakes, including defining them and stating the essay's purpose?

An introduction sets the stage for the essay, providing necessary background and stating the essay's main argument or purpose. It should engage the reader and clearly indicate what the essay will discuss.

"Define earthquakes."
In this part of the introduction, you should provide a concise definition of what an earthquake is. For example, an earthquake is the sudden shaking of the Earth's surface caused by the release of energy in the Earth's lithosphere, creating seismic waves.

"Introduce the topic and purpose."
Following the definition, you should introduce the specific topic related to earthquakes that your essay will explore (e.g., causes, effects, mitigation strategies). Clearly state the essay's purpose or thesis statement, which is the main argument or point you will be making throughout the essay.

The suggested essay structure for the introduction is:

• Define earthquakes: Briefly explain what an earthquake is.
• Introduce the topic and purpose: State the specific focus of your essay regarding earthquakes and clearly articulate your essay's main argument or objective.
