A divergent plate boundary is a boundary at which two tectonic plates move away from each other. As the plates move apart, magma

rises upward between them and erupts onto the ocean floor as lava. This lava cools quickly to form solid rock. Over time, these hardened lava flows build up on top of each other and are uplifted by tectonic forces to form mid-ocean ridges. Based on this information, what type of rock are mid-ocean ridges made of? metamorphic rock sedimentary rock igneous rock eroded rock

Answer:

igneous rock

Explanation:

Igneous rocks are rocks that form when magma or lava cools and hardens. Igneous rock that forms above the Earth's surface is extrusive. Igneous rock that forms below the Earth's surface is intrusive.

When magma erupts as lava onto the ocean floor at a divergent boundary, the lava cools quickly to form extrusive igneous rock. Over time, these hardened lava flows build up on top of each other and are uplifted by tectonic forces to form mid-ocean ridges.

d)It is beneficial to the whole species, but not to all of the individual members.

Answer:

d)It is beneficial to the whole species, but not to all of the individual members.

Explanation:

The behavior exhibited by the wasp is beneficial to the whole species, but not to all of the individual members as all wasps work all together to ensure the survival of newly fertilized females for the continuation of the species. All other wasps pay the supreme sacrifice working together in building nest, laying eggs, fertilization, all in a bid to ensure the continuation of their species, while most die leaving only the newly hatched females, that ensures continuation of the species.

The dependent variable is in this study or experiment is the distance both models took for each to stop after hitting the brakes as it depends on the independent variable.

Control variables are the variable is the variable that remains constant during the experiment so there would be no other influence than independent, in this case, speed or acceleration and same time hitting brakes are control variables.
