Which statement explains how convection currents affect the movement of plates? Gravity pulls one edge of a plate down into the

mantle, which causes the rest of the plate to move as well. Heat from Earth’s interior causes lithospheric plates to collide at convergent plate boundaries, causing volcanoes. Heat from Earth’s interior causes currents of hot rising magma and cooler sinking magma to flow, moving the crust along with them. As convection currents drift across the oceans, they bring the pieces of Earth’s crust with them as the supercontinent breaks apart.

Convection currents direct the movement of Earth's rigid tectonic plates in the planet's fluid molten mantle.

In places where convection currents rise up towards the crust's surface, tectonic plates move away from each other in a process known as seafloor spreading.

So, I would say the answer is:

As convection currents drift across the oceans,

they bring the pieces of Earth's crust with them as the supercontinent breaks apart.

Glad I could help, hv a good day :)

The answer is: heat from Earth’s interior causes currents of hot rising magma and cooler sinking magma to flow, moving the crust along with them. Mantle convection has nothing to do with the oceans and everything to do with differential heating of magma. Hope this image helps.

Which is an important difference between light-dependent (L-D) and light-independent (L-IND) reactions in photosynthesis? The L-
Yuliya22 [10]

Answer;

The L-D reactions require light energy and water, and the L-IND reactions require ATP, NADPH and CO2.

Explanation;

-Photosynthesis is the process by which green plants use light energy from the sun, water and carbon dioxide to make organic molecules, such as simple sugars.

-The process takes place in two phases; light dependent stage and light independent stage.

-During light dependent stage light energy is used to break down water molecules into hydrogen ions and oxygen atoms.

-Light independent reactions uses CO2 and the ATP and NADPH from light dependent reactions to produce sugar/ glucose. ATP is used to provide the energy for sugar synthesis and NADPH is used for electrons in the reduction of Carbon Dioxide into sugar.
