Which factors affect the development of the Florida peninsula? Check all that apply.
O coastal erosion
O sinkholes
O sand dunes
O underwater earthquakes
O aquifers
O volcanic activity
The correct answer is option A) Coastal erosions.
Coastal erosions affect the development of the Florida peninsula. Coastal erosion along the Florida coast is due to rising sea levels, natural disasters like frequent storms and hurricanes, numerous navigational inlets and other constructions, and poor developmental plans.
Why is erosion a problem in Florida?In addition to increased hurricanes, storms, and sea-level rise, much of the beach erosion is caused by man-made activity such as the construction of jetties and seawalls and poor planning for coastal development along the shoreline.
What is Florida doing to prevent beach erosion?The department's Coastal Construction Control Line (CCCL) Program protects coastal resources from improperly located and designed structures and activities that can destabilize the beach and dune system, cause erosion, expose an upland property to storm damage or interfere with public access.

O It has scenic canyons and caves.
O It has the state's most important waterways.
O It includes the state's highest peaks.
O It includes a series of elevations and depressions.
mark this and ratum
Answer:
It includes a series of elevations and depressions.
Explanation:
Ridges are basically small elevations and if you look at them from a flat surface, they might even look like small mountains. In reality they are only 700ft tall.
Valleys on the other hand are plains with not ridges or small mountains.
Therefore a ridge and valley region would consist of a series of elevations due to ridges and depressions due to the plain valleys.

D

The Ridge and Valley region is full of elevations and depressions. I also just had this on a quiz!

Explain how scientific knowledge is developed when people make observations about the natural world.
Answer:
Scientific knowledge is developed only when you make an observation about the natural world because without an observation, you will not question anything which mean there will be no scientific knowledge about the world around us. Scientific knowledge is built as people come up with hypotheses and theories, repeatedly test them against observations of the natural world, and continue to refine those explanations based on new ideas and observations. Observation is essential to the process of science.

Which is the best estimated pressure, represented in units of GPa, of the lower mantle? 110 GPa 220 GPa 305 GPa 360 GPa
The correct answer is A. 110GPa
Explanation:
Pressure refers to a force applied to a surface or object either by another object or factors such as the atmosphere. This is calculated considering the force applied and the area. Additionally, this factor can be measured using the unit gigapascals (GPa), which is more common in geography and related areas.
In this context, the lower mantle, which is the layer below the upper mantle has a pressure between 24GPa and 130GPa; and this is a high pressure if compared to the pressure in the surface. Thus, the estimated pressure in this zone is 110GPa because this is the only number that is between the range of pressure in this zone, while others show a higher pressure that is not found in this layer.
Answer:110 GPa
Explanation: I took the quiz
Contrast the formation of igneous rocks and the formation of metamorphic rocks

A republic is different from a direct democracy: In a republic, citizens elect representatives to pass laws and make decisions for them. Thus, option D is the correct option.
The way decisions are made is what distinguishes a republic from a direct democracy. In a direct democracy, decisions are made and legislation is voted on by the citizens themselves. This may entail events or meetings where everyone is given the chance to cast a vote on laws or policies.
On the other hand, under a republic, people choose representatives who act as their voice in government and enact laws. These officials are chosen through elections and given the power to speak for the interests of the people and make decisions in their place.
Thus, option D is the correct option.

What Are the (2) most important climatic factors for the Indian people?
Answer:
Latitudinal Location and Distance from the Ocean/Sea.
Explanation:
Latitudinal Location because it is the distance from the equator. The farther away from the equator you get, the hotter it gets, and vice versa.
Distance from the ocean/sea because the ocean/sea is a heat reservoir. It stores heat, and lets it out when its cool, therefore making places near the sea have either colder or warmer temperatures depending on the time of year.
Scientists find trilobites during a routine dig. Trilobites were common in the Paleozoic Era (540 to 245 million years ago) and went extinct during the late Permian period (248 million years ago). On another site, the scientists find ammonites. Ammonites lived during the Mesozoic Era (245 to 65 million years ago) and are not found after that period. What can be concluded about the rock layers? Choose all that apply.
A The rock layers must have formed at the same time because they both contain biozones.
B The rock layer containing the trilobites must have formed before the one containing the ammonites.
C The rock layer containing the trilobites must have formed after the one containing the ammonites.
D The rock layers must have formed at different times because they contain two different biozones.
Answer:
A and C
Explanation:
The rock layers must have formed at different times because they contain two different biozones. The rock layer containing the trilobites must have formed before the one containing the ammonites. The key thing to note here is that the Trilobites only lived from 540 to 248 million years ago. And that the Ammonites were from 245 to 65 million years ago. So there's a 3 million year gap between these 2 different creatures where neither of them existed. So the dig where the trilobites were found has to be at least 3 million years older than the dig where the Ammonites were found. So with that in mind, let's look at the options and see what makes sense.
The rock layers must have formed at the same time because they both contain biozones. * This is nonsense no matter what dates you're speaking of. In effect it claims that all rocks that indicate life were created at the same time. So this is definitely a bad choice.
The rock layers must have formed at different times because they contain two different biozones. * This is technically incorrect since it assumes that all biozones represent an unique period of time which is incorrect. However, since the biozones represented by the presence of Trilobites and Ammonites don't overlap, it is true that these these rock layers were formed at different times. I would have preferred if this option said "non overlapping biozones". But on the balance, I'd consider this option to be true, so it should be selected.
The rock layer containing the trilobites must have formed before the one containing the ammonites. * This is definitely true since the last Trilobite died about 3 million years before the first Ammonite lived. So this is a correct choice.
The rock layer containing the trilobites must have formed after the one containing the ammonites.
* This is the opposite of the previous option. And since the previous option was true, this option must be false. So this is a bad choice

In circle C shown below, a tangent has been drawn at point A. If m CBA 28 then explain why the measure of DAB must equal 62.
Answer:
The solution is shown below
Explanation:
From the image attached:
Line BC and line AC are the radii of the circle, therefore BC = AC.
Since BC = AC, the triangle ABC is an isosceles triangle with m∠CBA = m∠CAB = 28°
Also line ED is a tangent to circle C. From the circle theorems, a tangent to a circle is at right angle to the circle radius at point of contact. Since AC is a radii, ∠EAC = 90°
Therefore:
∠DAB + ∠EAC + m∠CAB = 180° (sum of angles on a straight line)
∠DAB = 180° - ∠EAC - m∠CAB
∠DAB = 180 - 90 - 28 = 62
∠DAB = 62°
