Iberian Peninsula Rotating Clockwise Due to Tectonic Forces
Scientists have found that the Iberian Peninsula, which includes Spain and Portugal, is slowly turning clockwise.
This happens because of the big pieces of Earth's crust called tectonic plates moving and pushing against each other.
The Eurasian and African plates are moving closer together every year, and this causes the land to change shape over a very long time.
A special area called the Alboran domain is moving westward, which helps create a curved mountain range called the Gibraltar Arc.
This movement makes the Iberian Peninsula rotate.
Even though we won't see big changes in our lifetime, understanding these movements helps scientists predict earthquakes and learn about how the Earth changes over millions of years.
The Iberian Peninsula is rotating clockwise due to tectonic forces between the Eurasian and African plates.
The Alboran domain's westward motion drives the formation of the Gibraltar Arc, influencing the peninsula's rotation.
The Eurasian and African plates are moving 4–6 mm closer each year, causing stress and deformation in the Earth's crust.
Scientists use earthquake records and satellite observations to study the peninsula's slow rotation.
The long-term effects of this rotation could include the Mediterranean becoming a closed sea and Africa and Europe joining in the west.
