Why Do We Have Seasons? Earth’s Tilt and Revolution Explained Simply

 Why Do We Have Seasons? Earth’s Tilt and Revolution Explained Simply

Seasons Are Not Random

Rainy season. Dry season. Harmattan.

It feels like the weather just changes on its own.

But it doesn’t.

👉 Seasons happen because of how the Earth moves… and how it is positioned.

What Causes Seasons?

Seasons are caused by two things:

Earth’s tilt

Earth’s revolution around the Sun

1. Earth’s Tilt (The Key Factor)

The Earth is not standing straight.

👉 It is tilted at about 23.5 degrees

What does this mean?

At different times of the year:

One part of Earth leans toward the Sun

Another part leans away

2. Earth’s Revolution Around the Sun

Earth moves around the Sun in a path called an orbit.

👉 This takes 365 days (1 year)

How Tilt + Movement Create Seasons

Let’s break it down simply:

☀️ When a part of Earth tilts toward the Sun:

It gets more sunlight

Days are longer

Temperature is higher

👉 This is summer

🌥️ When it tilts away:

Less sunlight

Shorter days

Cooler temperature

👉 This is winter

🌍 What About Nigeria?

Nigeria doesn’t experience extreme winter or summer like some countries.

Instead, we have:

Rainy season 🌧️

Dry season ☀️

Harmattan 🌫️

These are still influenced by: 👉 Earth’s tilt and position relative to the Sun

Why Seasons Matter

Seasons affect:

Farming 🌱

Weather patterns

Water availability

Daily life

Think About This

The weather feels random…

But it’s actually controlled by:

👉 The angle of the Earth in space.

Seasons are not just changes in weather.

They are the result of:

Earth’s tilt

Earth’s movement around the Sun
