During most of the Mesozoic Era, the Earth was ________. A.warmer than present B.about as warm as present C.cooler than present D.experiencing wild temperature fluctuations E.Unclear from the data presented. If you choose this answer explain what you are seeing.
Answer:
A.warmer than present
Explanation:
During most of the Mesozoic Era, the Earth was warmer than present.
This is because during the Mesozoic era the land were far away from water bodies which led to prevalence of deserts while today the land are much more closer to the water bodies. It’s a known fact that water bodies help in the thermoregulation and cooling of the atmosphere.
This is the main and feasible reason why the Earth was warmer in the Mesozoic era than now.

14. Given that 16x⁴+ - 4x³– 4b²x² + 7bx + 18 is divisible by 2x + b,
(a) show that b³ - 7b² + 36 = 0,
(b) find the possible values of b.
Answer:
(a) check the explanation
(b) the possible values of b is 6i or -29
Explanation:
Given function;
16x⁴ - 4x³– 4b²x² + 7bx + 18
(a)
factor of the given function = 2x + b
then, 2x + b = 0
x = -b/2
substitute the value of b into the given function;
16x⁴ - 4x³– 4b²x² + 7bx + 18
[tex]16(\frac{-b}{2} )^4 -4(\frac{-b}{2})^3-4b^2(\frac{-b}{2})^2 +7b(\frac{-b}{2})+18=0\\\\b^4+\frac{b^3}{2} -b^4-\frac{7b^2}{2} +18=0\\\\\frac{b^3}{2} -\frac{7b^2}{2} +18=0\\\\multiply\ through \ by \ "2"\\\\b^3-7b^2+36 =0 \ (shown)[/tex]
(b)
b³ - 7b² + 36 = 0
b²(b - 7) + 36 = 0
b²(b - 7) = -36
b² = -36 or b - 7 = -36
b = √(-36) or b = -36 + 7
b = √(-1) x √(36) or b = -29
b = 6i or -29

This photo shows a plateau. Which events could have caused this plateau to form
select the three correct answers.
Pls help this is urgent!
Answer:
Uplift raised the level of a piece of crust.
Mountains eroded.
Basaltic lava flowed from cracks in the crust.
Explanation:
A plateau can form in several different ways. It can form because of volcanic activity, the collision of plates, uplift of crust, and erosion.
Uplift that has raised a piece of crust can easily form this plateau. If the crust that is moving up is relatively flat at the top, then it will stick out in the surrounding area like a mountain will, but it will have a relatively flat top, thus making a plateau.
Erosion is very often a factor that creates plateaus. If there is a very large piece of crust that is much more solid than its surroundings, it will erode at a much slower rate. This will result in the crust around it to erode while it remains close to its initial form, thus sticking out as a higher relief form.
In the areas where there is or has been volcanic activity, it is common that plateaus as the one on the image are found. When the lava flows it fills in the valleys, cracks, holes, and when it solidifies it creates solid masses of igneous rocks. These rocks erode very slowly, so while all of the surroundings erode faster and lower down, it remains largely the same in the form of a plateau.

The frigid temperatures have allowed a lake to become ready for people to ice fish on it. What process has the lake undergone?
Answer:
When the entire lake reaches 40 F, the surface water cools further, dropping below 40 F. Because this water is now less dense than the surrounding water, it will stay on the top and continue to cool. Once the surface water falls to 32 F, it freezes. The freezing then spreads downward into the lake and the ice thickens

1. Decreasing magnetic field
2. Increasing magnetic field
3. Chemical combustion
4. Increasing electric field
1. Photosphere
2. chromosphere
3. Corona
4. Core
Answer:
Sunspots are associated with regions of increasing magnetic field. It is visible on the photosphere.
Explanation:
The region of the Sun that is visible to us is the photosphere. It is the lowermost layer of the solar atmosphere. This is the layer where the energy from the interior of the Sun bubbles up and is released as visible light.
One hypothesis is that sunspots are created by changes in magnetic fields in the Sun. Sunspots usually occur in pairs over regions of intense magnetic activity.
Hope the helps and have a nice day!!
Sunspots are associated with regions of increasing magnetic field. It is visible on the Photosphere.
A sunspot is an area on the Sun with a magnetic field that is about 2,500 times stronger than the Earth's. When there is a strong magnetic field, the magnetic pressure increases while the surrounding atmospheric pressure decreases.
As we know, the photosphere is the visible surface of the Sun. Due to the Sun's gaseous nature, this is not a solid surface but an atmospheric layer that measures about 100 km thick (extremely thin compared to the Sun's 700,000 km radius).
The photosphere is the lowest layer of the solar atmosphere. In this layer, sunlight (visible light) is released as a result of energy bubbling up from the Sun's interior.
Thus, Sunspots are associated with regions of increasing magnetic field. It is visible on the Photosphere. According to one hypothesis, sunspots are caused by changes in the Sun's magnetic field. Over magnetically active regions, sunspots usually occur in pairs.

There was the main difference of the acid and the normal rain. The acid rain was the slowly dissolves rocks and the normal rain are not the dissolves of the rock.
What is rock?
The rock, according to geology, is a part of the solid surface. The rock is the collection of these cemented mineral grains. The rocks are small and bigger. The small rocks are also known as pebbles. The type of natural resource is rock. The rocks are used for making the building.
The influence on the rock differs depending on whether it is acid rain or ordinary rain. Acid rain degrades rocks gradually as a result of chemical interactions between the acids and the ions in the stone. Pure water has a moderately acidic pH of 5.6, whereas acid rain has a pH around 4.2 and 4.4.
As a result, the normal rain from acid rain are the based on the rock breaks.

Solve for the value of p.
|(3p+1)°
(p+7)
Answer:
P=43
Explanation:
As, the both angles are linear, so if we add them, we will get 180°.
So, p+7 + 3p+1 = 4p + 8
So, 4p + 8 = 180
So, 4p = 180 - 8
4p = 172
P= 172/4
P = 43
So p+7 + 3p+7 = 43 + 7 + ( 3x43 + 1) = 180
Therefore, p = 43

The Old Man of the Mountain was a rock formation on the side of Cannon Mountain in New Hampshire. Scientists believe it formed 200 million years ago when the mountain was covered in glaciers. New Hampshire is known for its harsh, snowy winters. In the 1920s, scientists started noticing large cracks in the face of the mountain. In 2003, the rock formation collapsed.
The picture on the left shows the rock structure before its collapse. The picture on the right shows how the rock structure looks today. (The ghost image shows the part lost in the collapse.)
Answer:
what do you want to know?
Explanation:
Question 1
Part A: The Old Man of the Mountain is a rock formation on the side of a cliff. It was created when glaciers weathered the rock’s surface.
Part B: The cold, harsh winters of New Hampshire weathered the Old Man of the Mountain. This weathering likely led to cracks in its surface from frost wedging. The weight of snow and ice further weakened the structure, causing the rock to loosen and eventually erode.
Part C: The collapse of the Old Man of the Mountain happened quickly in 2003, like a landslide. However, the process was triggered through slow changes to the rock. The wind, ice, and snow from the New Hampshire winters gradually weathered the rock, weakening it and causing the formation to eventually collapse.

Part B: 11.9 meters
Part C: The steepness of the line represents the rate of erosion in meters per year.
Part D: y = 1.16x
Part E: Building the Canadian hydroelectric plant reduced the rate of erosion after 1906.
Part F: Hydroelectric dams use the flow of water to create power. The building of the dam decreased the speed and force of water flow over Niagara Falls as the water was diverted to the power plant. The reduced water flow resulted in a lower rate of erosion.
