The uppermost layer of the Earth is the crust, which is composed of solid rock and is relatively thin compared to the underlying layers. It includes both continental crust, which forms the landmasses, and oceanic crust, which lies beneath the oceans. The crust is where all terrestrial life exists and is characterized by various geological features such as mountains, valleys, and plains. It is divided into tectonic plates that float on the semi-fluid asthenosphere beneath.

Which layer of the earth contains the tectonic plates?
The plates are part of the crust, the upper layer of the Earth. The plates are moved by currents in the upper mantle. The plates and flexible upper mantle are referred to collectively as the lithosphere and sit atop the mantle layer called the aesthenosphere.

What is the layer of the earth that is composed of large plates that interlock and move over time?
The earth has tectonic plates are made up of Earth's crust and the upper part of the mantle layer underneath. The crust and upper mantle are called the lithosphere.
What is the top crust layer of earth called?
The top crust layer of the Earth is called the crust.
What is a layer of gas contained in the upper atmosphere?
The layer of gas contained in the upper atmosphere is called the ozone layer. It is important for protecting life on Earth by absorbing the majority of the sun's harmful ultraviolet radiation.
What is upper layer made of?
upper layer is made of mantle of the earth.
What is the most expansive layer of the Earth?
The most expansive layer of the Earth is the mantle, which makes up about 84% of the Earth's volume. It is located between the Earth's crust and the core and consists of solid rock that can flow slowly over long periods of time.

Is the second layer of the earth the upper mantle or the lower mantle?
upper mantle
What is the biggest layor of the earth?
The thickest layer of the Earth is the mantle, with or without the asthenosphere (the upper layer of mantle). However, the densest layer of Earth is the inner core.
Definition of upper crust of Earth?
The upper crust of the Earth refers to the outermost layer of the Earth's surface, composed of solid rock and soil. It is the thinnest layer of the Earth, ranging from a few kilometers thick beneath the oceans to about 70 kilometers thick beneath the continents. This layer is where most geological processes, such as earthquakes and volcanic activity, occur.
