Answer:
Proper cleanliness of water..
The diagram shows that ∠2 and ∠4 are the vertical angles.
<h3>What are vertical angles?</h3>
Vertical angles are the angles that are opposite of each other when two lines cross.
The statements are:
1. < 2 & < 4 are vert. angles
2. Lines M & N intersect at P
3. < 2 & < 3 are a linear pair
4. m < 2 + m < 3 = 180
5. <3 and < 4 are a linear pair
6. m < 3 + m <4 =180
7. m < 2 + m < 3 = m < 3 + m < 4
8. m < 2 = m < 4
9. < 2 =~ <4
Here are the reasons:
1. Given
2. Def of vertical angles.
3. Def if. Linear pair
4. Angle addition postulate
5. Def of a linear pair
6. Angle addition postulate
7. Substitution property
8. Subtraction property
9. Def of =~ angles.

Answer:
Subsidence is so slow that there seems to have been no depression of the upper surface of the lithosphere, so depositional environments are mostly the
same as those in surrounding areas; the succession is just thicker. These
successions are also more complete, however—there are fewer and smaller
diastems—so at times the basin must have remained under water while surrounding areas were emergent. (A diastem is a brief interruption in
sedimentation, with little or no erosion before sedimentation resumes.)
Size, shape: rounded, equidimensional, hundreds of kilometers across
Sediment fill: shallow-water cratonal sediments (carbonates, shales, sandstones),
thicker and more complete than in adjacent areas of the craton but still
relatively thin, hundreds of meters.
Hopefully that helps!
Answer:
The high islands of the Pacific were formed by seismic activity whereas the low islands of the Pacific were formed by coral growth. Continental islands and oceanic islands were formed by volcanic activity.
High islands often have fertile soils and lush rainforests. In contrast, low islands are often less fertile than high islands. Some low islands lack freshwater sources.
