Ecosystems, which are made up of a dynamic network of both living and nonliving entities, undergo steady change through time. New plants and animals either thrive or suffer when they are introduced to a region. Sometimes thriving species supplant native species.
The agroecosystem, human ecosystem, urban ecosystem, soil biological organisms, and rainforest ecosystem are examples of natural ecosystems. An ecosystem is a dynamic system that includes both living things like plants and animals and non-living items like the sun and soil.
Ecological succession or a shift in the environment refers to the process that causes organisms to vary in their structural appearance over time in a particular region. The species structure and habitat change are indicators of ecosystem change.
Many different biological species make up the diversity of a given area (species richness), while biodiversity refers to the measurement of the dominance of particular species in a given area (species evenness).
The release of soil nutrients owing to rainfall, a result of constant change in an ecosystem, and the development of plants due to favorable changes in the climate are examples of positive changes in the ecosystem. As a result of soil erosion brought on by rains breaking down the soil and climate change, which lowers air quality, the ecosystem has undergone unfavorable alterations.

O The box will not move.
The box will slide toward Shane.
The box will slide toward Susan.
The box will be perpendicular to both Shane and Susan.
If Shane and Susan both push on a box with a force of 25N, but in opposite directions, then the box will not move.
What do you mean by force?
A force is a push or pull on an object as a result of its contact with something else. When two objects collide, a force is applied to each of them. The force is no longer felt by the two objects when the interaction ceases. Forces only exist as a result of contact.
Shane and Susan both exert 25N of force on a box.
As a result, if shane force is represented by = +25 N.
Then susan force would be= -25 N
Now,

Why is central america prone to earthquakes? question 11 options: the region lies on the border of two tectonic plates. the soil is soft and easily moves. the building codes are old and outdated. there is no clear reason why the area is prone to earthquakes.
The correct answer is option A: the region lies on the border of two tectonic plates.
Central America is prone to earthquakes because the region lies on the border of two tectonic plates.
A large number of earthquakes occur in Central America because it is located in a region that is seismically quite active in the world.
Most active regions are along the North American - Caribbean plate boundaries and Cocos - Caribbean plate boundaries.
Earthquakes are abundant in these areas due to the excessive relative movement between the tectonic plates. However, active volcanoes are also responsible for the convergent movement of the plates along the boundaries.
To put it simply, Central America holds a lengthy history of destructive and damaging earthquakes.

explain why earth's temperature changes with latitude and with the seasons. why is it unlikely that the winter olympics—typically held in february—would take place in the mountains of new zealand?
The earth's temperature changes with latitude and with the seasons because of the earth's tilt and form, the sun's rays fall on it at various angles.
The sun's rays impact indirectly the higher the latitude. It is highly improbable that the winter Olympics will be staged in the mountains of New Zealand since lower pressures at higher altitudes make it colder and the Earth's rotation and inclination on its axis vary the seasons.
Since 1880, the temperature of the Earth has risen by 0.14° F (0.08° C) per decade, but since 1981, the pace of warming has increased by more than twice that, to 0.32° F (0.18° C) per decade. According to NOAA's temperature data, 2021 was the sixth-warmest year ever.

Land distribution became an important economic issue throughout much of latin America because a majority of land was in the hands of a few wealthy farmers.
In any third world country land distribution inequality has been an odd feature. And the biggest reason for it had been related to the favours received by those close to power or powerful feudal lords. The same was the reason in Latin America till late 2015-16. Also the curious case of land availability for cultivation has not been helped by reforms in many countries even.
According to Oxfam’s analysis, more than 50 per cent of productive land in Latin America is held by the top one percent of the largest farms. In Colombia, over 67 per cent of productive land is concentrated in 0.4 per cent of agricultural landholdings. In Chile and Paraguay, one percent of farms occupy over 70 per cent of the land. A quick case analysis as mentioned by Oxfam :
Although small family farms account for more than 80 per cent of agricultural operations, they occupy 13 per cent of productive land. Once again, Colombia leads as the most unequal country as 84% of the smallest farms occupy less than 4% of productive land. In Paraguay, over 91% of farms hold just six per cent of land.
So overall even when the large land share belongs to farmers, the greater share of productive land is still with bigger feudal.

List at least three points of evidence for plate tectonics below and explain how each supports the theory of plate tectonics.
The existence of fossils, glaciers, and complimentary coasts all provide evidence for how the plates originally interacted.
Plate tectonic activity frequently leads to magma formation, igneous intrusions, metamorphism, volcanic activity, earthquakes, faulting, and folding. Deep fault systems split the crust of the world into six large and roughly twenty smaller parts.
The discovery of very identical fossils in rock blocks separated by great distances and oceanic stretches was one of the earliest lines of evidence pointing to the existence of plate tectonics. It implied that those land parcels had once been linked.
The locations of earthquakes and volcanoes, frozen at solidification, coral islands, ocean trenches, magnetic striping, the age of the rocks that make up the ocean's crust, and the progressive expansion of rifts are all evidence that certain places have moved, as well as evidence that neighboring locations were not always next to each other and/or had different orientations.

Three points of evidence for plate tectonics are:-
1. The shapes of many continents are such that they look like they are separated pieces of a jigsaw puzzle. For eg., if you look at the map of the world and see the shape of the east coast of North and South America then it seems they are relative to the shape of the west coast of Africa and Europe.
2. Many fossil comparisons along the edges of continents that look like they fit together suggest species similarities that would only make sense if the two continents were joined at some point in time in the past and hence confers the movement of the plates.
3. There are ridges, such as the Mid-Atlantic Ridge where plates are separating that are produced by lava welling up from between the plates as they pull apart. Also, there are mountain ranges being formed where plates are pushing against each other eg., the Himalayas, which are still growing.
There are seven major tectonic plates.
Movement in tectonic plates can cause tsunamis, earthquakes, and volcanic eruptions. These are some of the major proofs of plate tectonics.

The study of how people and the environment interact is known as cultural geography. Though there are many avid football supporters in Montana, for instance, the state's culture is less football-centric than that of the South. This is due, in part, to the milder winters in the South, which make it easier for people to play football.

Orographic lifting
When an air mass travels over rising terrain, it is propelled from a low elevation to a higher level, a phenomenon known as orographic lift. The rapid adiabatic cooling of the air mass as it ascends can cause the relative humidity to reach 100%, which can lead to clouds and, under the appropriate circumstances, precipitation.
Frontal Lifting
