The systematic subfield of geography is geographic information science (gis), which is concerned with the collection, analysis, and interpretation of spatial data.
Regional geography is also a subfield of geography, but it is more focused on the study of specific regions and their characteristics. Cartography is the art and science of mapmaking, while cultural geography is the study of the relationship between human culture and the natural environment. Astrology is not a subfield of geography.
Computer-based technologies called GIS, or geographic information systems, are used to store, view, analyze, and interpret geographic data. The geographic location of features is determined by geographic data, often known as spatial or geospatial data. A geographic information system (GIS) is a computer program that collects, stores, verifies, and presents information about locations on the surface of the Earth. Streets, buildings, and plants can all be displayed on a single map using GIS.

The horse, introduced by European traders, changed the lifestyles of Native Americans on the Great Plains.
which of the following contributes to the ozone hole over the south pole? cfcs a polar vortex polar stratospheric clouds
All of the options listed contribute to the formation of the ozone hole over the South Pole, but the primary factor is the presence of chlorofluorocarbons (CFCs) in the atmosphere.
When CFCs are released into the air, they can rise into the stratosphere and react with ozone molecules, breaking them down and reducing the amount of ozone in the atmosphere. This process is made worse by the presence of polar stratospheric clouds, which provide a surface for chemical reactions to take place.
Additionally, the polar vortex (a persistent, high-altitude wind pattern) can isolate the polar region and trap pollutants there, exacerbating the effects of CFCs and stratospheric clouds. Overall, reducing the use of CFCs is the most effective way to mitigate the formation of the ozone hole.

Identify the TRUE statement.
Oa. The tide-generating force is a combination of only two forces, the gravitational attractions of the Sun and Moon.
Ob. Since the Sun is much larger than the Moon, its gravity is the biggest contributing factor to the tide-generating force.
Oc. A flood tide that arrives as a visible wall of water is called a tidal bore.
Od. Tidal reach means the farthest inland the water goes at high tide.
The TRUE statement is option Od. Tidal reach means the farthest inland the water goes at high tide.
The tide-generating force is a combination of only two forces, the gravitational attractions of the Sun and Moon. This is known as the gravitational pull of the Moon and the Sun, which causes a bulge in the ocean's water levels, leading to high tides. Although the Sun's gravity is stronger than the Moon's, it is the Moon that has a greater effect on tides because it is closer to the Earth. Option B is incorrect since the size of the celestial bodies does not determine their effect on tides. Option C is also incorrect since a tidal bore is a type of tidal phenomenon where a wave of water moves upstream against the current of a river or narrow bay.

No, not all parallels and meridians cross each other at right angles on both the globe and the Mercator projection. While the concept of parallels and meridians is the same on both, the Mercator projection distorts the angles and shapes of land masses as you move further away from the equator.
This means that while some parallels and meridians may cross each other at right angles on the Mercator projection, others may not due to the distortion of the map. On a globe, however, all parallels and meridians do intersect at right angles.Parallels, also known as lines of latitude, run horizontally on a map and are parallel to the equator. Meridians, also known as lines of longitude, run vertically on a map and converge at the poles. On a globe, parallels and meridians cross each other at right angles, forming a grid-like pattern.
On a Mercator projection, a type of map projection that represents the Earth on a flat surface, the parallels and meridians also appear to cross each other at right angles. However, it is important to note that the Mercator projection introduces some distortions in the representation of the Earth's surface, such as the distortion of size and shape near the poles. Despite these distortions, the crossing of parallels and meridians at right angles on the Mercator projection remains true for practical purposes.In summary, both on a globe and a Mercator projection, parallels and meridians cross each other at right angles.

When one part of a wave is slowed, but another portion isn't, the wave will bend in the direction of the slower part of the wave. This phenomenon is known as ________________.
When one part of a wave is slowed, but another portion isn't, the wave will bend in the direction of the slower part of the wave. The phenomenon is known as Refraction.
Refraction occurs when a wave, such as light or sound, passes through different media, causing a change in its speed. As a result, the wave bends towards the slower part, altering its direction. When the wave encounters a medium with a different density or composition, its speed changes, and consequently, so does its wavelength. The part of the wave that slows down first will experience a greater change in direction compared to the part that maintains its speed.
Refraction plays a crucial role in various natural and technological phenomena. For example, in optics, refraction allows lenses to focus light, enabling devices like cameras, telescopes, and eyeglasses to function effectively. In atmospheric science, the refraction of light, as it passes through Earth's atmosphere, creates optical illusions, such as mirages and the apparent bending of objects near the horizon.
Additionally, refraction is an essential concept in underwater acoustics, where sound waves are bent as they travel through layers of water with different temperatures, densities, and pressures. This effect is critical for sonar systems and underwater communication.
In summary, refraction is the bending of a wave when it passes through different media, causing its speed to change. This phenomenon is vital in understanding and utilizing various natural and technological processes.

which of the following processes is common in high-latitude regions (e.g. siberia in russia) to produce precipitation?
The process that is common in high-latitude regions to produce precipitation is the uplift of air masses due to the convergence of different air masses with different temperatures and densities.
This happens when cold air from the poles meets warm air from the equator, or when different wind systems collide. As the air masses rise, they cool and condense, forming clouds and eventually producing precipitation. In high-latitude regions like Siberia in Russia, the process that is common for producing precipitation is known as "frontal precipitation." This occurs when warm air masses meet cold air masses, leading to the formation of a weather front.

explain the impact of river rejuvenation on the grading of a river
Answer: River rejuvenation can have a significant impact on the grading of a river. When a river is rejuvenated, it means that the river has started to erode deeper into its bed, creating steeper banks and a steeper gradient. This can be caused by a variety of factors, such as tectonic uplift, changes in sea level, or changes in base level.
As the river erodes deeper, it will transport larger sediment sizes and create a steeper gradient. This can result in a change in the river's grading, or the distribution of sediment sizes along the river bed. With a steeper gradient, the river will be able to transport larger sediment sizes downstream, resulting in a coarser bed material.
In addition to changes in sediment size, river rejuvenation can also lead to changes in the river's channel pattern, such as the formation of meanders or the creation of a new channel. These changes can impact the river's hydraulic geometry, or the relationship between channel geometry and flow.
Overall, river rejuvenation can have a significant impact on the grading of a river, resulting in changes in sediment size, channel pattern, and hydraulic geometry. These changes can have both positive and negative impacts on the river ecosystem and nearby communities, depending on the specific circumstances.

To find the initial speed of the second rock when it is thrown straight down from the edge of a 45m high cliff so that both rocks hit the ground at the same time, we can follow these steps:
1. Determine the time it takes for the first rock to fall 45 meters.
We'll use the equation: [tex]s =ut + \frac{1}{2} gt^{2}[/tex],
where s is the distance (45 m), g is the acceleration due to gravity (9.8 m/s^2), and t is the time in seconds.
The initial velocity, u=0
2. Solve for t: 45 = 0.5 * 9.8 * [tex]t^{2}[/tex]
Rearrange and solve for t: t^2 = (45 * 2) / 9.8 ≈ 9.18.
So, t ≈ √9.17 ≈ 3.03 seconds.
3. Since the second rock is thrown one second later, it has 3.03 - 1 = 2.03 seconds to reach the ground.
4. Now, we'll use the equation: [tex]s =ut + \frac{1}{2} gt^{2}[/tex],
where s is the distance (45 m), g is the acceleration due to gravity (9.8 m/s^2), and t is the time in seconds (2.03 s).
5. Solve for u: 45 = u * 2.03 + 0.5 * 9.8 * [tex]2.03^{2}[/tex]
Rearrange and solve for vi: u = (45 - 0.5 * 9.8 *[tex]2.03^{2}[/tex]) / 2.03 ≈ 12.22 m/s.

in the northern hemisphere when the cold front overtakes warm fronts around the low pressure system an front is created and ow altitute air starts forming the midlatitute cyclone
In the northern hemisphere, when a cold front overtakes a warm front around a low-pressure system, it creates a front known as an occluded front. This front marks the end of the midlatitude cyclone's life cycle, as it represents the point where the cold front has caught up and overtaken the warm front.
As the cold front approaches the warm front, it forces the warm air to rise rapidly, creating a narrow band of intense precipitation. This precipitation band moves along the warm front until it is completely overtaken by the cold front, forming an occluded front. At this point, the midlatitude cyclone's energy source, the temperature difference between the warm and cold air masses, is no longer present. Without this source of energy, the cyclone begins to weaken and eventually dissipate.
As the cyclone weakens, the low altitude air around the system begins to form into a new high-pressure system, marking the end of the cyclone's life cycle. This process is known as the occlusion process and is an important part of understanding midlatitude cyclones in the northern hemisphere.

Is north always straight toward the top of the Mercator projection?
Yes, in the Mercator projection, north is always straight toward the top of the map. This is because the Mercator projection is a cylindrical projection that preserves the shape of objects and lines, but distorts the size and scale towards the poles.
Therefore, the equator is placed straight across the middle of the map, while the poles are stretched out towards the top and bottom. As a result, north is always located at the top of the Mercator projection.The Mercator projection was developed by Gerardus Mercator in 1569 and has become one of the most popular world map projections due to its simplicity and ability to represent lines of constant course as straight segments. However, some criticize the Mercator projection for exaggerating the size of land masses near the poles and diminishing the size of land masses near the equator.
