Let's say the hippos all disappeared. Because the hippos are prey for the tertiary predators like a hyena, the population of the predators would decrease while the population of the grass increased.

If the predators disappeared the preys' population would spiral out of control and all the primary producers like leaves and grass would become scarce. Additionally, the decomposing carcass of animals like dead predators and prey create food for microorganisms which make fertile soil; thus, causing the land to become barren.

Food, fuel, and raw materials for production are all produced using natural resources. Natural resources such as coal, natural gas, and oil offer heat, light, and power.

One of the three ways that streams transport their load of sediment is through suspension.

Suspended sediment consists of small, light particles that are carried within the water column without settling to the streambed. These particles can include fine sand, silt, and clay. The amount of sediment that a stream can suspend is largely determined by the velocity of the water flow.

Faster-moving water can carry larger and heavier particles than slower-moving water. Suspended sediment can have a significant impact on water quality and ecosystem health. High levels of sediment can reduce water clarity, block sunlight from reaching aquatic plants, and damage fish and other aquatic organisms.

It is therefore important to monitor and manage sediment levels in streams to maintain healthy aquatic ecosystems.

Alfred wegener discovered that there are similar mountain ranges on both sides of the atlantic ocean. The mountain ranges are similar in age and composition. This information helped Alfred Wegener form his theory of continental drift.

One of the earliest theories put up by geologists for how continents might migrate through time is called continental drift. The science of plate tectonics has now supplanted the theory of continental drift. The scientist Alfred wegener is most closely connected with the concept of continental drift. Wegener wrote a paper outlining his notion that the continents were "drifting" across the Earth, occasionally crashing through oceans and into one another, in the early 20th century. He referred to it as continental drift.

Geologists rejected Alfred Wegener's theories in the wake of his 1912 proof that the continents are moving, which he could not explain. Harry Hess, who used the data of seafloor spreading to explain what moved continents, backed up Wegener's theories nearly 50 years later.

Answer: The unit of pressure most commonly used in meteorology is the millibar

Explanation: Hope this helps!

The unit of pressure that is commonly used in meteorology is the "millibar" (mb).

In meteorology, pressure is an important measurement that helps to predict weather conditions. The unit of pressure commonly used in this field is the millibar (mb). One millibar is equal to 100 pascals, or 0.001 bar. It is a smaller unit of pressure that is more convenient for measuring the changes in atmospheric pressure that occur in weather systems.

Other units of pressure used in meteorology include the "hectopascal" (hPa) and the "inch of mercury" (inHg). However, the millibar is the most commonly used unit of pressure in meteorology because it is a smaller unit that allows for more precise measurements of atmospheric pressure changes.

The amount and timing of precipitation a region receives is ultimately controlled by its climate, which is determined by a variety of factors, including latitude, altitude, distance from large bodies of water, prevailing winds, and topography.

These factors affect the amount of solar radiation that a region receives, the amount of moisture in the air, and the patterns of atmospheric circulation. For example, regions near the equator receive more solar radiation and are generally warmer than regions at higher latitudes. This leads to differences in atmospheric pressure and circulation patterns, which can affect the amount and timing of precipitation. In addition, topography plays an important role in determining the amount and timing of precipitation. Mountain ranges can cause moist air to rise and cool, leading to precipitation on the windward side of the mountains. On the leeward side of the mountains, however, the air is often dry and can lead to arid or semi-arid conditions. Overall, the complex interplay of these factors ultimately determines the climate and precipitation patterns of a region.

Convergent boundaries occur when two tectonic plates move towards each other. Subduction zones are a type of convergent boundary where one plate is forced beneath another plate into the mantle.

This usually happens when an oceanic plate collides with a continental plate, as the denser oceanic plate is forced down into the mantle. Continental collision is also a type of convergent boundary, but instead of one plate subducting beneath the other, both plates collide and buckle, causing the formation of mountains. If an oceanic plate is colliding with a continental plate, it is likely a subduction zone. If two continental plates are colliding, it is likely a continental collision. Another way to distinguish is by looking at the geological features in the area. Subduction zones often result in volcanic activity and the formation of trenches, while continental collision results in the formation of mountain ranges.
Distinguish between convergent boundaries involving subduction zones and continental collisions, you can consider the following points:
1. Types of plates involved:
- Subduction zones: These occur when an oceanic plate converges with either another oceanic plate or a continental plate. The denser oceanic plate subducts, or slides beneath, the less dense plate.
- Continental collisions: These occur when two continental plates converge, as both plates are of similar density and neither can subduct. Instead, they collide and form mountain ranges.
2. Geological features:
- Subduction zones: These boundaries are characterized by deep oceanic trenches, volcanic island arcs (in oceanic-oceanic subduction), or volcanic mountain ranges along the edge of the continent (in oceanic-continental subduction).
- Continental collisions: These boundaries result in the formation of large mountain ranges, such as the Himalayas or the Alps, due to the compression and uplift of the Earth's crust.
3. Seismic and volcanic activity:
- Subduction zones: These areas are prone to frequent earthquakes and volcanic activity due to the friction and pressure caused by the subducting plate. The melting of the subducting plate generates magma, leading to volcanic eruptions.
- Continental collisions: These areas experience frequent earthquakes due to the immense pressure and stress from the colliding plates. However, volcanic activity is generally absent in continental collision zones, as there is no subduction of a plate to generate magma.
By considering these factors, you can distinguish between convergent boundaries involving subduction zones and those involving continental collisions.
