fill in the blank : a characteristic of alpine glaciation is a valley with a cross section that is ________ .
A characteristic of alpine glaciation is a valley with a cross section that is U-shaped.Alpine glaciation refers to the process of glacial activity in mountainous regions.
One distinctive feature of alpine glaciation is the formation of U-shaped valleys. These valleys exhibit a characteristic cross section that is wide and U-shaped, with a flat bottom and steep, often vertical, sides.
The formation of U-shaped valleys occurs through a combination of erosional and depositional processes. As glaciers advance, they exert immense pressure and erode the landscape through mechanisms like plucking and abrasion. This erosive action removes and transports large quantities of rock and sediment, deepening and widening the valley. The glacier's movement also contributes to the lateral erosion of the valley walls, resulting in the distinct U-shaped cross section. When glaciers retreat, they leave behind glacial deposits, such as moraines, which further shape and define the valley.
In contrast to V-shaped valleys, which are typically formed by rivers, U-shaped valleys are a characteristic product of alpine glaciation. The unique U-shaped cross section is a testament to the powerful and transformative impact of glaciers on the mountain landscape.

examine this map of the continent of africa. At which latitudes
is the atmostphere rising? at which latitudes is it sinking? how
does this atmostpheric circulation influence the contient's
climates
The atmosphere is rising at the equator and sinking at the subtropical latitudes.
The atmospheric circulation pattern influencing the continent's climate is known as the Hadley Cell. At the equator, solar radiation is strongest, causing air to heat up and rise, creating a low-pressure zone. This ascending air forms a band of atmospheric rising motion known as the Intertropical Convergence Zone (ITCZ). As the air rises, it cools and releases moisture, leading to frequent rainfall and lush tropical climates in equatorial regions.
At higher latitudes near 30 degrees north and south, the air that rose at the equator starts to descend. This sinking motion creates high-pressure zones known as subtropical highs, such as the Sahara High in Africa. As the air descends, it becomes warmer, leading to drier and more arid conditions in the subtropical regions.
The combination of rising air at the equator and sinking air at the subtropics sets up a global atmospheric circulation pattern that influences Africa's climates.

Which power of a telescope might be expressed as "0.5 seconds of arc"?
The power of a telescope is typically expressed in terms of its resolving power or angular resolution, which is the smallest angle between two points that the telescope can distinguish.
The term "0.5 seconds of arc" refers to the angular resolution of a telescope and represents the smallest angle that the telescope can distinguish between two points in the sky. This angular resolution is typically dependent on the size of the telescope's aperture or lens diameter, and the wavelength of the light being observed. A smaller angular resolution means that the telescope can distinguish finer details in the observed object. Thus, a telescope with an angular resolution of 0.5 seconds of arc would be able to distinguish between two points in the sky that are separated by a distance of 0.5 seconds of arc, which is a very small angle. This is an important factor for astronomers who want to study objects with high levels of detail.

Karst terrain could form in areas where the metamorphic rock calcite is prevalent because the rock contains the mineral quartz
Karst terrain is a unique landscape formed by the dissolution of soluble rocks such as limestone, dolomite, and gypsum. These rocks are composed of minerals such as calcite, which can be easily dissolved by water. Therefore, the formation of karst terrain is closely related to the type of rock present in an area.
Metamorphic rock is a type of rock that has been subjected to high pressure and temperature, causing it to undergo significant changes in its mineral composition and texture. In particular, the presence of certain minerals in metamorphic rock can affect the formation of karst terrain.Calcite marble, which is formed from limestone or dolomite that has undergone metamorphism, is a common rock type that can form karst terrain.
This is because calcite is highly soluble in water and can be easily dissolved, creating voids and cavities in the rock that eventually lead to the formation of sinkholes, caves, and other karst features.Other types of metamorphic rocks such as quartz marble and quartzite are less likely to form karst terrain because they do not contain significant amounts of soluble minerals. Calcite schist, on the other hand, may contain enough calcite to potentially form karst terrain, but the presence of other minerals such as mica and quartz can hinder the dissolution process

Explosion in a grain silo. Spark explosions constitute hazards in facilities handling grain or powder (a very famous explosion occurred in a biscuit factory 50 years ago). Commonly the powder is blown into a silo through cylindrical, grounded pipes. The danger occurs if: ∣ E
∣≥3.0×10 6
N/C For electric fields this large "dielectric breakdown" occurs, which enables to charge to move through the air. This is what happens during sparks or lightning strikes. (Note that the energy of the spark also needs to be greater than 150 mJ to ignite the powder, but we'll ignore that for the moment). Suppose a stream of negatively charged powder was blown through a cylindrical pipe of radius R=6.0 cm. Assume that the powder and its charge were spread uniformly through the pipe with a volume charge density rho. a) Using Gauss' law, find an expression for the magnitude of the electric field ( E
) in the pipe as a function of radial distance r from the pipe center. b) Does E
increase or decrease with increasing r (distance from the center of the pipe)? c) Is E
directed radially inward or outward? d) For rho=1.1×10 −3
C/m 3
(a typical value at the factory), find the maximum E
, and determine where that maximum field occurs. e) Could sparking occur, and if so, where?
a) E = (ρ/2ε₀) r.
b) E increases with increasing r.
c) E is directed radially outward.
d) E(max) = (1.1×10^(-3) C/m³ / 2ε₀) (6.0 cm).
e) Sparking could occur if E(max) ≥ 3.0×10^6 N/C.
a) To find the expression for the magnitude of the electric field (E) in the pipe as a function of radial distance r from the pipe center, we can apply Gauss' law. Gauss' law states that the electric flux through a closed surface is proportional to the charge enclosed by that surface.
Considering a cylindrical Gaussian surface with radius r, coaxial with the pipe, we can apply Gauss' law to the electric field E:
∮E⋅dA = (1/ε₀) ∫ρdV,
where ∮E⋅dA represents the surface integral of E over the closed surface, ε₀ is the vacuum permittivity, and ∫ρdV represents the integral of the volume charge density ρ over the volume enclosed by the surface.
Since the powder and its charge are spread uniformly through the pipe, the charge enclosed by the Gaussian surface is q = ρV, where V is the volume of the Gaussian surface. The volume of the cylindrical Gaussian surface is given by V = πr²L, where L is the length of the pipe.
Therefore, the equation becomes:
E(2πrL) = (1/ε₀) ρ(πr²L),
Simplifying, we find:
E = (ρ/2ε₀) r,
which gives the magnitude of the electric field as a function of radial distance r from the pipe center.
b) From the expression obtained in part (a), we can see that E is directly proportional to r. Therefore, as r increases, the magnitude of the electric field E also increases.
c) The electric field E is directed radially outward. This can be inferred from the equation obtained in part (a) where E is proportional to r.
d) For ρ = 1.1×\(\sqrt{x}\)(-3) C/m³, we can substitute this value into the equation from part (a) to find the maximum E and determine where it occurs. The maximum electric field occurs at the surface of the pipe, where r = R.
E(max) = (ρ/2ε₀) R,
Substituting the given values, we have:
E(max) = (1.1×\(\sqrt{x}\)(-3) C/m³ / 2ε₀) (6.0 cm),
where ε₀ is the vacuum permittivity.
e) To determine if sparking could occur and where, we need to compare the magnitude of the electric field to the threshold value for dielectric breakdown, ∣E∣ ≥ 3.0×\(\sqrt{x}\) N/C.
If the maximum electric field E(max) is greater than or equal to the threshold value, then sparking could occur. If E(max) is below the threshold, sparking is unlikely.
By comparing E(max) obtained in part (d) with the threshold value, we can determine if sparking is possible in the given scenario.
