Ours - Earth.
According to Oklahoma Edition of McDougal Littell Science Grade 7 the Terrestrial Planet that has the oldest least changing surface is Mercury. Mars has wind that carries sand that changes its surface. Venus has volcanoes and tectonic plates that change its surface. We know that Earth has erosion, volcanoes and tectonic plates that change the surface. This leaves Mercury.
It describes the ongoing changes to the surfaces of terrestrial worlds. This is because terrestrial surfaces change over time. The moon and mercury are considered geologically dead because their surfaces have remained the same for billions of years.
No. The Earth is a rocky planet, divided into physical and chemical layers, which have evolved from a molten blob of material that accreted from sun orbiting debris nearly 4.6 billion years ago. Although pockets of molten (liquid) rock exist in the mantle and crust, these two layers are essentially composed of solid metamorphic, igneous and to a small extent, sedimentary rock. The outer core is the only liquid layer, composed of liquid iron and nickel. The inner core is a solid metal alloy composed mainly of iron and nickel. See the link below for a diagram.
Earth is constantly experiencing geological, atmospheric, and biological changes which contribute to its dynamic state as a planet. These changes include movements of tectonic plates, weather patterns, and shifts in biodiversity. Overall, these changes make Earth a continually evolving and complex system.
The solid part of the Earth's surface is known as the Earth's crust. Comprising both the continental crust and the oceanic crust, it is the outermost layer of the Earth. The continental crust, primarily composed of granite, forms the continents, while the oceanic crust, composed mainly of basalt, underlies the ocean floors. The Earth's crust is crucial for supporting life and geological processes, providing a solid foundation for the diverse ecosystems on land and influencing the planet's geophysical dynamics, such as tectonic movements and volcanic activity.
Earth certainly meets all three of those criteria.
tectonic platesContinents
The surface of the Earth is broken into about a dozen large tectonic plates that float on the semi-fluid asthenosphere beneath them. These plates interact at their boundaries, leading to processes such as earthquakes, volcanic eruptions, and mountain building. This theory is known as plate tectonics.
Perhaps the planet "Terra" otherwise known as "Earth".
The Earth's surface is broken into large pieces called tectonic plates. These plates float on the semi-fluid asthenosphere layer beneath them and interact at plate boundaries, where geological phenomena such as earthquakes and volcanic eruptions occur.
The surface of the Earth is broken into several large tectonic plates that float on the semi-fluid asthenosphere. These plates interact at their boundaries, leading to phenomena like earthquakes and volcanic activity.
The Lithosphere.
The tectonic plates are located in Earth's lithosphere, which is the outermost layer of the planet. The lithosphere is divided into several large and small tectonic plates that float on the semi-fluid asthenosphere below. Movements of these plates are responsible for earthquakes, volcanic activity, and the shaping of Earth's surface features.
A tectonic planet is a planet with a surface that is composed of moving plates. These plates interact with each other, leading to processes like earthquakes, volcanic activity, and the creation of mountains. Earth is an example of a tectonic planet.
The portion of the Earth that is broken into tectonic plates is the Lithosphere. It's not one solid sheet but broken into slabs called plates. They are in motion and drift over the asthenosphere. It's a lot like a slab of ice drifting over the surface of a lake.
it's a lithosphere
The crust is not a solid shell; it is broken into huge, thick plates that float on the liquid mantle.
