“How can we represent environmental impact based on resource consumption?”

 

Every society has an environmental impact. But since each society has different levels of resource consumption and utilization, each one is different. So how can we quantify this? Well, we can measure impact based on the average of the amount used multiplied by its energy efficiency and the total population. This is known as the I = PAT equation where I is the Environmental Impact P is the Total Population A is the Level of Affluence (how many resources are used) and T is the Technological Efficiency.

“How does rock and soil move downhill?”

 

In the universe, the only constant thing is change, and Geology is no exception. Soils, rock, and debris at the top of a mountain will move downhill overtime due to gravity. This process is known as Mass Wasting and is one of the contributing factors to mudslides.

“What is Clay?”

 

Many children around the world play with clay when they are young. But what exactly are they? Well, when natural rock or soil material is highly grounded, it can combine with a large amount of other elements overtime to make Clay. Clay’s flexibility and strength when hardened have made it useful in building materials and early writing utensils.

“How can mudflow happen?”

 

It is well known that the ground is made of dirt. And when this dirt becomes moist in the event of rainfall, it will have less cohesiveness and can flow out. These events are known as Mudslides and can trigger extensive property damage.

“How is rock and soil material transported from one part of the Earth’s surface to another?”

 

Weathering can break down rocks and soils on the Earth into smaller components. Once they are small enough, they can be easily scooped up by natural Earth fluids such as wind and rainwater runoff. This process is known as Erosion and is one of the most fundamental aspects of geology.

“How are rocks broken down over time?”

 

Thanks to entropy, nothing stays permanent over time. This is very true on the geological scale. Over time, rocks on the Earth’s surface will be broken down by contact with the Earth’s Atmosphere, Water, and Biological Organisms. This is known as Weathering and is one of the primary changers of the Earth’s surface.
