Geography Mapping And Practical Skills: Quiz!

The contour pattern shown matches cross-section D because it has a concave shape, similar to the contour lines in the pattern. Cross-sections A, B, and C do not have the same concave shape as the contour lines, making them incorrect matches.

A hill is a round and high piece of land, not as large as a mountain, which has contours forming an oval or circle shape. It is a natural elevation of the earth's surface that rises above the surrounding land. Hills are commonly found in various landscapes and can vary in size and shape. They are often covered with vegetation and can provide scenic viewpoints.

A delta is a physical feature formed at the end of a river where sediment tends to settle. As the river flows into a body of water, such as a lake or an ocean, the velocity of the water decreases, causing it to deposit the sediment it has been carrying. Over time, this accumulation of sediment forms a landform that is triangular in shape, with multiple distributaries branching out from the main river channel. Deltas are commonly found in areas with high sediment supply and low wave energy.

An oxbow lake is formed when a river cuts across the narrow neck of a meander, resulting in a "U" shaped lake. This occurs when the river takes a shorter path, leaving behind a curved, isolated body of water. The formation of an oxbow lake is a natural process that happens over time due to erosion and changes in the river's course.

The correct answer is gradient. Gradient is a measure of the slope of the land, indicating the rate at which the land surface rises or falls. It is commonly used in geography, geology, and engineering to describe the steepness or incline of a slope. Vertical exaggeration refers to the vertical scale used in a map or diagram to make the relief features appear more pronounced. Steepness is a synonym for gradient, describing the degree of inclination or steepness of a slope. Elevation, on the other hand, refers to the height or altitude of a point or surface above a reference level.

The correct answer is ▲ 220. A trig station reading is typically represented by a symbol, such as a triangle (▲), followed by a numerical value. In this case, the symbol ▲ represents the trig station reading, and the numerical value is 220. The other options, such as TS, BM, ●, and SH, do not typically represent trig station readings.

A braided channel is a single stream that comprises a network of intertwining channels. This means that instead of having a single, straight channel, there are multiple smaller channels that weave and intertwine with each other. This can occur when a river has a high sediment load and the flow is not strong enough to carry all the sediment in a single channel. As a result, the sediment gets deposited and forms smaller channels within the main channel, creating a braided pattern.

A ridge is a narrow long hilltop or crest of high land. This definition suggests that a ridge is a specific type of elevated landform that is long and narrow in shape. It typically refers to a high point or crest along a mountain range or hilly terrain. The other options, such as a steep rocky slope, an extensive area of flat land, the foot of a mountain, or a narrow finger of land jutting out to sea, do not accurately describe the concept of a ridge.

Sediment or point bars tend to build up on the inside of a meander's bank because the water velocity is weaker on the inside bank compared to the outside bank. As the water flows around the curve of the meander, it moves faster on the outside bank, causing erosion, while the slower-moving water on the inside bank allows sediment to accumulate and form a bar. This process is known as deposition and is responsible for the formation of point bars in meandering rivers.

The gradient between F and G is 1/11.

The formula for gradient is G = difference in height divided by distance. This formula calculates the steepness or slope of a line or surface. It is commonly used in physics, engineering, and geography to measure changes in elevation or inclination. By dividing the difference in height by the distance traveled, we can determine how much the height changes per unit of distance.

The head or apex of a meander tends to be the deepest point of a river. This is because the water flow is concentrated at the outer bank of the meander, causing erosion and deepening of the river channel at that point. As the water flows around the bend, it loses energy and deposits sediment on the inner bank, resulting in shallower areas. Therefore, the deepest point of a river is typically found at the head or apex of a meander.

A cross-section is a representation of a landscape or geological feature in a vertical plane. Vertical exaggeration is the ratio of vertical scale to horizontal scale in a cross-section. A good cross-section should provide enough exaggeration to clearly show the vertical variations in the landscape or geological feature, but not so much that it distorts the proportions or makes the cross-section difficult to interpret. The range of 4-10 for vertical exaggeration provides a good balance between exaggeration and accuracy, allowing for clear visualization of vertical variations without excessive distortion.

The given points represent the path of a meander. The letters CD indicate the starting and ending points of the meander. Therefore, the correct answer is CD.

Spurs are projections of high land towards lower land, which makes statement 1 true. The depressions with concave slopes between spurs are called re-entries, making statement 3 true as well. Therefore, the correct answer is 1 & 3.

Contours illustrate height, slope, and shape of the land. This means that contours not only show the elevation or height of the land but also the steepness or slope of the terrain. Additionally, contours depict the shape or form of the land, allowing us to visualize its features such as valleys, ridges, or plateaus. The statement that contours illustrate height and shape but not slope of the land is untrue.

The contour pattern shown in the image indicates a series of V-shaped valleys that are interconnected and extend down the slope. This pattern is characteristic of interlocking spurs, which are formed when a river cuts through a landscape with alternating layers of hard and soft rock. The river is forced to meander around the resistant rock layers, creating the interlocking spurs. This landform feature is commonly found in mountainous regions and is indicative of a youthful or actively eroding landscape.
