Question

figure 1: tectonic plates map
consider this map of the world with the geothermal cooking spots marked. what do all these places have in common?
see circled areas

1. locations such as iceland, azores islands, rotorua, and yunomine onsen, a. are / b. are not all located near a plate boundary.
2. at plate boundaries, how does the heat trapped within earth cause the tectonic plates to move? you may choose more than one.

a. pull apart
b. push together
c. slide past one another
d. stay still
which of the following facts could be used in an explanation of why cooking using hot springs is possible? you may choose more than one.
a. heat from earth’s mantle often escapes to the surface at plate boundaries.
b. earth’s tectonic plates are constantly moving and even breaking apart to form new plates.
c. thermal energy from earth’s mantle can heat up groundwater, causing hot springs and geysers.
d. more than half of the heat generated by earth comes from radioactive decay within the crust and mantle.
e. material within earth’s mantle rises as it heats, then cools near the crust and sinks again. this convection causes the movements of tectonic plates.

Explanation:

1. By observing the tectonic - plates map and the marked locations (Iceland, Azores islands, Rotorua, and Yunomine Onsen), we can see that they are near plate boundaries.
2. At plate boundaries, the heat from the Earth's interior can cause the plates to pull apart (divergent boundaries), push together (convergent boundaries), or slide past one another (transform boundaries).
3. Cooking using hot springs is possible because heat from Earth's mantle can escape to the surface at plate boundaries and heat up groundwater, causing hot springs and geysers. Also, the movement of tectonic plates and the heat from the mantle are related to the formation of these geothermal features.

Answer:

1. A. are
2. a. Pull apart, b. Push together, c. Slide past one another
3. a. Heat from Earth’s mantle often escapes to the surface at plate boundaries., c. Thermal energy from Earth’s mantle can heat up groundwater, causing hot springs and geysers.
