Answer:
oceanic crust sinks because it is denser and has higher specific gravity than the more silicon aluminum enriched continental crust. What drives substitution is convection and conduction in outer core of earth, that heat , only a small part of which is due radioactive isotopes, has to make it's way to Earth's surface by both conduction and convection. Iron and nickel o have the highest specific gravities of the 10 most common elements in the Milky Way Galaxy. This is why oceanic crust sinks and is subducted continental crust has to have a lot more force applied before it inks, because it doesn't want to sink.
D. They do not produce electricity.
Passive solar heating is a technique where the sun's energy
is used for heating spaces. It does not generate electricity but can save substantial
electricity by making use of thermal mass. Materials that have a high density
such as concrete and bricks absorb and store electricity. Along with operable windows
and thermal chimneys, thermal mass is being
utilized to take advantage of sun exposure.
Answer:
I'm pretty sure it gets through these joint type things that connects the cave to the surface

Hope this helps:)....if not then sorry for wasting your time and may God bless you:)
On the geological maps in question, the cratonic basins that contain thick sequences of sedimentary rocks which overly the Precambrian basement, show the <em><u>youngest rocks</u></em> toward the center of the basin.
Geological maps are tools created and used by scientists to show the arrangement of the geological elements of a specific area. This can include:
- Rock types
- Cracks and faults
- Minerals
- Groundwater
- Ages
and much more, depending on the area and detail of the map created.
On a detailed geo-map, we can understand not only the area we are initially standing on but also where to find geological areas with similar sediment compositions and information on the age of the rocks. This is done due to the way the map stacks the units in terms of age, from the <u>youngest </u>at the <em><u>top </u></em>to the <u>oldest </u>at the <em><u>bottom</u></em>.
Cratonic basins are areas where geological elements are widely distributed and often filled with <u>shallow water </u>as well as <u>sedimentary rocks</u>. The rocks at the center of these basins show the <em><u>youngest</u></em> <em><u>rocks </u></em>at the center due to the previously mentioned <u>aging sequence </u>used by the <u>maps</u>.
