04.03 Heat Flow Inside Earth

Question 1

Convection

Answer 1

movement caused by hotter, less dense material rising while cooler, denser material sinks

Question 2

Hotspot

Answer 2

where molten magma rises to just underneath the surface of Earth, creating a bulge or volcanic activity

Question 3

Convergent boundaries

Answer 3

when tectonic plates move towards each other and slowly collide.

Question 4

Subduction

Answer 4

when one plate moves over the other, pushing it deep into the mantle.

Question 5

Divergent boundaries

Answer 5

primarily in oceans, when tectonic plates move apart. When the plates move apart, hot rock seeps in to fill the space and volcanoes or new land may form.

Question 6

seafloor spreading

Answer 6

When there are divergent boundaries in plates under the sea, we call this seafloor spreading

Question 7

Mantle

Answer 7

Layer with partially melted material that moves the tectonic plates

Question 8

Transform boundaries

Answer 8

Tectonic plates that slide past each other

Question 9

Transform boundaries

Answer 9

Tectonic plates that slide past each other

Question 10

Volcano

Answer 10

Created when tectonic plates allow molten magma to escape and build up over time

Question 11

Ocean basin

Answer 11

Created underwater when tectonic plates move apart and the space fills with new, hardened crust

Question 12

Mountain

Answer 12

Created when tectonic plates collide and uplift the rocky material above the surface of Earth
