What is sonar mapping?
A technique used to create detailed maps of the sky using sound waves.
A technique used to create detailed maps of the land using sound waves.
A technique used to create detailed maps of the human body using sound waves.
A technique used to create detailed maps of the ocean floor or other bodies of water using sound waves.
What are mid ocean ridges?
Underwater mountain ranges formed along tectonic plate boundaries.
Underwater caves formed by volcanic activity.
Underwater canyons formed by erosion.
Underwater valleys formed along tectonic plate boundaries.
This explains what the land looks like by including elevations of land. It can be seen on a detailed map of the surface features of land. It includes the mountains, hills, creeks, ocean depths, seafloors, and other bumps and lumps on a particular hunk of earth.
seafloor spreading

mid-ocean ridge
Explain sea floor spreading.
Sea floor spreading is the process of forming new oceanic crust at mid-ocean ridges and pushing older crust away.
Sea floor spreading is the process of forming new continental crust at mid-ocean ridges and pushing older crust away.
Sea floor spreading is the process of forming new oceanic crust at subduction zones and pulling older crust towards the continents.
Sea floor spreading is the process of forming new oceanic crust at deep-sea trenches and pushing older crust towards the continents.
What are the characteristics of mid ocean ridges?
Volcanic islands formed along convergent plate boundaries
Underwater mountain ranges formed along divergent plate boundaries
Underground caves formed along subduction zones
Deep trenches formed along transform plate boundaries
What are the main differences between magma and lava?
Lava is found in the Earth's mantle, while magma is found in the Earth's core.
Magma is hotter than lava.
Magma and lava are the same thing.
Magma is beneath the Earth's surface, while lava reaches the Earth's surface.
What evidence supports the theory of sea floor spreading?
Fossil records, ocean currents, and tides.
Volcanic activity, earthquakes, and tsunamis.
Different ages of rocks from different areas of the oceanic crust, changes found in magnetism of rocks found in the crust, and presence of mid-ocean ridges,.
Weather patterns, climate change, and ocean salinity.
What is plate tectonics?
The scientific theory that describes the large-scale movement of Earth's crust.
Mountains, hills, plateaus, valleys, and plains are the types of
countries
landforms
rocks
plates
Ocean trenches are
Shallow areas in the ocean floor.
