Both ridges and trenches are boundaries between lithospheric (tectonic) plates.
What else can I help you with?
What are 2 geological features that can occur at plate boundaries?
Two geological features that can occur at plate boundaries are mountain ranges, formed from the collision of two plates, and deep ocean trenches, formed at subduction zones where one plate is forced beneath another.
What physical feature occures along ocean trenches and ridges?
The physical feature that occurs along ocean trenches and ridges is seafloor spreading. This process is when new oceanic crust is formed at mid-ocean ridges through volcanic activity, pushing the older crust away from the ridge towards ocean trenches where it is eventually subducted back into the mantle.
What did scientist learn when they mapped the ocean floor in the 1800s?
there is a mid-atlantic ridge
Do the sinking of mid-ocean ridges into the ocean trenches prove the Continental Drift theory?
The sinking of mid-ocean ridges into ocean trenches does not directly prove the Continental Drift theory. However, it supports the theory by providing evidence of plate tectonics and the movement of tectonic plates. The theory of plate tectonics explains how continents move and interact with each other over time.
Do Plates move together or apart at mid ocean ridges?
Mid Ocean ridges separate the plates and create new seafloor. Places where plates converge and disappear into the abyss are called trenches. The Marianas Trench is the deepest trench in the world.
How do you contrast mid-ocean ridges and trenches?
Mid-ocean ridges are the birthplace of oceanic crust. Trenches represent the destruction and burial of oceanic crust. They are at opposite ends of the Earth's convection currents that move through the asthenosphere.
How is the formation of mid ocean ridges and trenches different?
Stop trying to cheat on ur homework
What are 2 geological features that can occur at plate boundaries?
Two geological features that can occur at plate boundaries are mountain ranges, formed from the collision of two plates, and deep ocean trenches, formed at subduction zones where one plate is forced beneath another.
How do ocean floor features such as trenches and mid ocean ridges form?
Ocean floor features like trenches and mid-ocean ridges form due to tectonic processes. Trenches are created at convergent boundaries where one tectonic plate subducts beneath another, leading to deep oceanic depressions. Conversely, mid-ocean ridges form at divergent boundaries where tectonic plates are pulling apart, allowing magma to rise and create new oceanic crust. These dynamic processes shape the ocean floor over geological time.
How do ocean floor features such as trenches and mid ocean ridges from?
Ocean floor features like trenches and mid-ocean ridges form primarily due to tectonic plate movements. Trenches occur at convergent boundaries, where one plate subducts beneath another, creating deep, elongated depressions. In contrast, mid-ocean ridges form at divergent boundaries, where tectonic plates move apart, allowing magma to rise and create new oceanic crust. These processes are driven by the dynamics of the Earth's mantle and the heat flow from the Earth's interior.

What does deep-ocean basin consist of?
the deep ocean basin consist of the deepest part of the ocean . :)
How do ocean floor features such as trenches and mind-ocean ridges form?
Ocean floor features like trenches and mid-ocean ridges form due to tectonic plate interactions. Trenches are created at convergent boundaries where one plate subducts beneath another, leading to deep, elongated depressions. In contrast, mid-ocean ridges develop at divergent boundaries where tectonic plates move apart, allowing magma to rise and create new oceanic crust. These processes are driven by the dynamics of plate tectonics and mantle convection.
Is the earths lithosphere thicker in the vicinity of ridges or in the vicinity of trenches?
The Earth's lithosphere is generally thicker in the vicinity of trenches than around mid-ocean ridges. At mid-ocean ridges, where new oceanic crust is formed through volcanic activity, the lithosphere is relatively thin. Conversely, at subduction zones near trenches, the lithosphere is thicker due to the presence of older, denser oceanic crust being forced down into the mantle.
What did scientist learn when they mapped the ocean floor in the 1800s?
there is a mid-atlantic ridge
Marine magnetic anomaly belts run parallel to?
Mid-Ocean Ridges
What is the floor of the ocean called?
The floor of the ocean is called the seabed or ocean floor. It is made up of different features such as abyssal plains, trenches, ridges, and volcanoes.
