Deltas is created when a river carries sediment along on its way to the ocean.

DELTARiver deltas or estuaries are deposits in estuaries that are formed when river water meets other waters that have a weak or stagnant current rate. The low-speed water flow is unable to carry sediment from the river so that the sediment settles in the estuary. Deltas generally form in the open ocean, beach, or lake.

The size and shape of the delta depends on the processes that occur in the sediment-carrying waters and sediment-receiving waters.In addition, the size, shape, and location of the sediment-receiving waters also affect the evolution of the delta.

River deltas play an important role in human civilization because the location of the delta is the center of agricultural production and settlements. Deltas also provide protection for the shoreline and affect the supply of drinking water. From an ecological point of view, deltas play an important role as a place to live for various species.

The contour interval represents the difference in elevation between adjacent contour lines on a topographic map. For example, if the contour interval is set to 20 meters, this means that there is a difference of 20 meters in elevation between each adjacent contour line on the map. This information helps the reader of the map to understand the relative steepness or flatness of the land and to identify changes in elevation.

The contour interval is a key aspect of topographic maps that describes the vertical distance between contour lines. Contour lines are used to show the shape and elevation of the land, and the contour interval helps to interpret the map by providing information about how much the land changes in elevation over a given distance.

The contour interval is chosen based on the scale of the map and the complexity of the terrain. For maps that cover large areas with relatively gentle slopes, a larger contour interval may be used to simplify the map and make it easier to read. For maps that cover smaller areas with complex or steep terrain, a smaller contour interval may be used to show more detail and provide a better understanding of the land's shape and elevation.

It is important to note that the contour interval is not a fixed value but can be adjusted to suit the needs of the map and the information being conveyed. A smaller contour interval will provide more detail about the land's elevation, while a larger contour interval will simplify the map and make it easier to understand.

Answer:

The majority of Africa, India, and Indonesia were post-World War II colonies of superpowers like Britain, France, Japan, and the United States. The colonizers exploited these countries for cheap labor and resources. When the colonies finally gained independence, the colonizers still exerted influence over the countries' economies. Several economists argue that, as a result of this outside influence, these countries cannot easily move through Walt Rostow's process for modernization. Instead, they stay somewhat subjugated to their former colonizers, who continue to dictate world trade and the global economy.

The mass of the item and the gravitational acceleration are the two pieces of information required to compute the gravitational force acting on the object.

Because of their mass, objects are subject to the gravitational force. It is the driving force behind all of the universe's masses. Thus, there will always be an attraction between an object and the earth or another object.

The mathematical formulation of Newton's law provides the gravitational force exerted on an object:

F = ma

Where:

f  is the force

m is the object's mass

gravitational acceleration, or a.

As a result, both the object's mass and gravitational acceleration are required to determine an object's gravitational force.

A desert is a biome characterized by very little rainfall. It typically receives less than 10 inches of rainfall per year and can experience periods of weeks or even months without any precipitation.

The desert is known for its extreme dryness and lack of rainfall. This biome is characterized by its hot, arid climate and sparse vegetation. The vegetation is mostly composed of drought-resistant plants and animals that are adapted to survive in the harsh environment. The soil is composed of sand and other minerals, and it is often nutrient-poor and unable to support much life.

The lack of rainfall in the desert is the primary cause of its extreme dryness. The desert receives very little moisture from precipitation, and what little it does receive quickly evaporates due to the hot climate. This lack of moisture leads to a lack of water for plants and animals to use for survival. The high temperatures also cause the air to be dry, resulting in very low humidity levels. This low humidity further contributes to the dryness of the desert.

The lack of rainfall in the desert makes it one of the harshest and most unforgiving biomes on Earth. Despite these extreme conditions, some plants and animals have adapted to survive in the desert.

The flow of magma directly applies force to tectonic plates. Option A.

The movement of magma beneath the Earth's surface is one of the primary forces responsible for the movement of tectonic plates.

The hot magma rises from the Earth's mantle, creating a large pressure gradient between the mantle and the Earth's crust. As a result, the magma pushes the tectonic plates, causing them to move.

The force of the moving magma is strong enough to overcome the friction of the plates and cause them to move in the direction of the magma flow.

This is why the plates move towards the mid-ocean ridges, which are areas of the Earth's surface where the magma is actively rising.

The pressure and force of the magma are powerful enough to move the plates in opposition to the Earth's gravity, creating the phenomenon of continental drift.

The movements of the tectonic plates in turn affect the formation of volcanoes, earthquakes, and other geological phenomena.

Sand and other granular materials are materials that are composed of many individual grains or particles. Although they have a solid appearance, they are not solid in the traditional sense and have the ability to flow. This flow property of sand and other granular materials makes them behave like a fluid.

When we talk about the flow of a material, we mean its ability to change shape and move in response to external forces, such as gravity. Sand and other granular materials are not considered liquids or gases, but they can exhibit fluid-like behavior due to their tendency to flow.

This flow behavior of sand is seen when we pour sand from a container or a hopper. The individual grains of sand move and rearrange themselves in response to gravity, allowing the sand to flow out of the container and form a pile on the ground. The flow of sand is a result of the interparticle interactions between the individual grains.

In some cases, the flow of sand can become extremely fast and can even become hazardous, as seen in sandstorms and sand avalanches. The flow of sand is influenced by various factors, such as the size and shape of the individual grains, the packing density of the grains, and the external forces acting on the sand.

In conclusion, sand and other granular materials have the ability to flow and exhibit fluid-like behavior, making them a unique class of materials that can be both solid and fluid at the same time. This flow property of sand makes it an important material in various fields, including construction, agriculture, and industrial processes.

The relative humidity of the air when the readings on a sling psychrometer are 18°C for the dry bulb and 14°C for the wet bulb is 65%.

The percentage of water vapour in the air that is actually in the air compared to the maximum amount of water vapour the air can hold at a given temperature is known as relative humidity. A psychrometer is an instrument used to measure relative humidity.

1. Given parameters:

Dry bulb reading = 18°C

Wet bulb reading = 14°C

To solve this, obtain the difference between the wet and dry bulb temperature;

Temperature difference = Dry bulb reading - Wet bulb reading

                                        =    18°C - 14°C  = 4°C

Now we would compare this value with that of the relative humidity table.

The dry bulb and temperature reading should be traced for the point where they coincide, this will give the relative humidity = 65%.

2. Given parameters:

Dry bulb reading = 12°C

Wet bulb reading = 11°C

Temperature difference = 12°C-11°C = 1°C

If this is compared to the relative humidity table, the relative humidity is 90%.

The presence of tropical plant fossils in Antarctica is a result of a significant shift in Earth's climate that took place millions of years ago.

During the late Cretaceous period, approximately 100 million years ago, the Earth was much warmer than it is today, and Antarctica was located at a much different latitude, closer to the equator. This allowed for the growth of tropical vegetation, including forests and swamps, in what is now Antarctica.

As the Earth's climate cooled and the continents shifted over millions of years, Antarctica moved to its current location at the South Pole and became covered in ice and snow. Today, Antarctica is one of the harshest environments on the planet, with extremely cold temperatures and limited vegetation.
