Answer:

Lower layer is older than the upper layer

Explanation:

The unconformity is defined as the time of non-deposition. In simple words, it a contact surface between the older and younger sedimentary type of rocks, that results from the erosion particles over a specific period of time.

These sediments are deposited over one another over a due course of time, forming sedimentary rock sequences due to the compaction and lithification process. From the sequences it can be determined that the layers of rock that are at the bottom are considered to be the oldest layers, whereas the layers that are on the top are the younger layers. This is also known as the law of Superposition.

Hence, the lower layers are older than the upper layers.

i hope this helped

They have no true nucleus as the DNA is not contained within a membrane or separated from the rest of the cell, but is coiled up in a region of the cytoplasm called the nucleoid. Prokaryotic organisms have varying cell shapes.

Briefly discuss interpretations of your observations and results. Include in your discussion, any conclusions drawn from the res

VMariaS [17]

Answer:

In comparison to Part 1 of this experiment, we observed similar reactions when determining the make up of our unknown. When testing for Mn2+ we observed a color change that resulted in a darker brown/red color, when testing for Co2+ we observed the formation of foamy bubbles but we could not conclude that a gas had formed, when testing for Fe3+ the result was a liquid red in color, when testing for Cr3+ we observed no change, when testing for Zn2+ we observed the formation of a pink/red liquid, when testing for K+ we observed the formation of a precipitate, when testing for Ca2+ we observe the formation of a precipitate. Sources of error may have occurred when observing whether or not an actual reaction had taken place or not, using glassware that wasn't fully cleaned, or the accidental mix of various other liquids in the lab

What type (or two types) of energy is “heat energy on earth escapes into space”?

Gemiola [76]

Answer:

I think it's c). <em>Radiation. </em>I wasn't really sure so I done a go o.gle search and that is what I found. If you want further information, here it is: On Earth, heat travels by conduction, convection and radiation. In space, conduction and convection are almost entirely non-existent. Radiation is the primary way that heat travels in space. Pls let me know if this helps. Mark as brainliest if u can.
