<u>Answer:</u>
Composting food scraps in the cafeteria to reduce landfill waste would have the greatest impact in reducing the school’s ecological footprint.
Option: (C)
<u>Explanation:</u>
- Reducing the ecological footprint means bringing about some changes in lifestyle and living to improve the biocapacity.
- Compositing food scraps in the cafeteria to reduce landfill waste is the best option that the environmental club can apply to reduce the school's ecological footprint.
- This step can help to increase productivity of soil as well as reduce waste in landfill site.
- The option of incineration of trash causes air pollution. Likewise, reducing recycling bins will not be helpful in decreasing the ecological footprint.
- Instead, it causes the unmanaged collection of trash in school environment.
Answer:
The earth’s crust is broken into separate pieces called tectonic plates (Fig. 7.14). Recall that the crust is the solid, rocky, outer shell of the planet. It is composed of two distinctly different types of material: the less-dense continental crust and the more-dense oceanic crust. Both types of crust rest atop solid, upper mantle material. The upper mantle, in turn, floats on a denser layer of lower mantle that is much like thick molten tar.
Each tectonic plate is free-floating and can move independently. Earthquakes and volcanoes are the direct result of the movement of tectonic plates at fault lines. The term fault is used to describe the boundary between tectonic plates. Most of the earthquakes and volcanoes around the Pacific ocean basin—a pattern known as the “ring of fire”—are due to the movement of tectonic plates in this region. Other observable results of short-term plate movement include the gradual widening of the Great Rift lakes in eastern Africa and the rising of the Himalayan Mountain range. The motion of plates can be described in four general patterns:

Collision: when two continental plates are shoved together
Subduction: when one plate plunges beneath another (Fig. 7.15)
Spreading: when two plates are pushed apart (Fig. 7.15)
Transform faulting: when two plates slide past each othe
Explanation:
Answer:
Analogous or convergent structure.
Explanation:
Analogous structures can be defined as structures that have similar purposes but look completely different from each other. in other words it means that they serve the same functions in different species, but they are independently evolved. Examples of analogous structures are
- wings on butterfly, bats and birds
- Fins in penguins and fish
Answer:
The hydrosphere
Explanation:
The atmosphere interacts with the hydrosphere to redistribute water over the surface of Earth.
