Respuesta :
The false statement is lithospheric plates do not move.
Lithospheric plates always move because they are affected by the heat produced by the Earth's core. This causes molten rock in the mantle layer to move. This movement process takes place with certain patterns and speeds that are repeated and are called convection current.
Further explanation
The lithosphere is always moving because it is located above the asthenosphere. The asthenosphere is a clay and heat layer found beneath the crust of the Earth and above the Earth's mantle.
The lithosphere is the outermost layer of Earth that has a thickness of 1,200 Km with an average density of 2.8 grams / cm³.
The parts of lithosphere are:
1. SIAL (Silica and Aluminum) layer / Crust Layer
→ A layer of the Earth composed of Silica (SiO2) and Aluminum (AL2O3) which consists of continental crust and oceanic crust.
Characteristics: Solid and there are various types of rocks such as sedimentary rocks, granite, andesite, and metamorphic rocks.
a. Continental crust, is the solid part consisting of granite and basalt rocks.
b. Oceanic crust, is the solid part consisting of sediments in the sea, volcanic rocks, gabbro, and peridotites.
2. SIMA layer (Silica Magnesium)
→ The layer of the Earth composed of Silica (SiO2) and Magnesium (MgO).
Characteristics: the density of the SIMA layer is greater than the SIAL layer and has an average thickness of 65 Km.
