As a massive cloud of gas falls due to gravity, its rate of rotation should increase (due to the law of conservation of angular momentum).
The correct option is A.
What factors contribute to gravitational collapse?The contraction of the astronomical object due to the impact of its gravity, which tends to drive matter toward the center of gravity, is known as gravitational collapse.
What does momentum conservation have to say about just a collapsing gas cloud?The same logic that causes a skater's arms to spin faster as they draw their arms closer to their body causes this same collapsing cloud simply spin faster as it shrinks.

Faults are fractures along which rock has shifted in relation to the opposite side. A fracture is typically caused by a violent damage to the bones, which disrupts or breaks the integrity of bone tissues or bony cartilage. Fracture types include simple, complex, incomplete, and complete.
Compound fractures (sometimes known as "open fractures") tear the skin, exposing the bone and potentially causing additional soft tissue injury and infection.

write a brief statement of a hypothesis you think might best explain the variation in the geothermal gradient within earth.
The rise in temperature with depth in the Earth's crust is known as the geothermal gradient. Within the first 3 to 5 kilometers (2 to 3 miles) of the Earth's surface, a typical geothermal gradient in normal continental crust is approximately 25°C/km.
The gradient varies between the near surface and 400 ft (122 m), depending on how the atmosphere and moving ground water affect it. Temperature rises with depth almost usually below that zone.
It suggests that the Earth's surface is receiving heat from the planet's warm center. For every kilometer of depth, the temperature rises by about 25°C on average.

As a giant Cloud of gas collapses due to gravity, you would expect its rate of rotation to increase.
It is believed that when the enormous cloud evaporates, all of its energy remains constant (no energy is lost). If the massive cloud compresses itself, the conservation of energy and angular momentum dictates that the cloud's rotation rate must increase. Compression, which maintains the mass of the gas particles while decreasing their potential energy and increasing their kinetic energy and angular momentum, causes this to happen.
The conservation of energy is one of the fundamental tenets of Physics. According to the conservation of energy principle, the total quantity of energy in a closed system remains constant and neither new energy can be created nor old energy can be destroyed. Both small-scale systems and the huge universe are subject to these laws.

rank the following earth materials in order of their most likely occurrence, starting at earth's surface. think about moving from the crust to the mantle, and then to the outer and inner cores.
Earth materials in order of their most likely occurrence, starting at earth's surface are:
1. Granite and Basalt, Increasing amounts of olivine and pyroxene,
2. Fe-Mg silicates and oxides, Molten iron with nickel,
3. crystalline iron and iron-nickel alloy.
The crust, mantle, outer core, and inner core are the four major layers that constitute the earth's interior. The outer core is a viscous liquid, the inner core is a dense solid, the mantle is a viscous molten rock, and the crust is a silicate solid. Lighter sodium potassium aluminum silicate rocks, like granite, make up the continental crust. The thick iron magnesium silicate igneous rocks that make up the oceanic crust, however, include basalt.
Silicate rocks that make up the mantle are more abundant in iron and magnesium than the crust above them. Iron combined with nickel (nife) and minute quantities of lighter metals make up the outer core. Most experts agree that the inner core consists mostly of iron (80%) and a little amount of nickel (nife).

Identify four types of regions.
Calculate how many days of solar insolation at 250 watts/m2 would be required to melt the arctic ocean surface ice coverage from 14 x106 km2 down to 4 x106 km2.
28.24 days of solar insolation would be required to melt down the artic ocean surface.
Intensity of solar radiation = 250 watt/m²
= 250 Js⁻¹/m²
Thickness of ice coverage = 2m
Ice coverage to be melt = 14 million km² - 4 million km²
= 10 million km²
= 10 × 10,00,000 km²
= 10⁷ km²
= 10⁷ × 10⁶m
= 10¹³m
Heat reaches to surface per second = 250 Js⁻¹/m² × 10¹³m
= 2.5 × 10¹⁵ J/s
Now,
Total volume of ice = 10¹³ m² × 2m
= 2 × 10¹³ m³
Latent heat of ice = 3.33 × 10⁵J/Kg
Density of ice = 917 kg/m³
Total mass of ice = 917 × 2 × 10¹³
= 1834 × 10¹³kg
∴Heat required to melt whole ice coverage = Mass × Latent Heat
= 1834 × 10¹³kg × 3.33 × 10⁵J/Kg
= 6.11 × 10²¹ J
Total time taken to melt whole ice = 6.11 × 10²¹ J / 2.5 × 10¹⁵ J/s
= 2.44 × 10⁶s
Since, 1 Day = 86400s
∴ 2.44 × 10⁶s = 2440000/86400 Days
=28.24 Days
Thus, 28.24 days of solar insolation would be required to melt down the artic ocean surface.

The correct answer is temperatures over land are colder than those over water at the same latitude in water .
Latitude is used to calculate how far north or south of the Equator you are. It is calculated using 180 fictitious lines that are drawn in circles east-west of the equator. Parallels are the names for these lines. An imaginary ring connecting all points that share a parallel is known as a circle of latitude.
Latitudes are horizontal lines that indicate how far away from the equator a location is. Longitudes are vertical lines that represent the east and west directions relative to Greenwich, England's meridian.
