Based on the duration and effect of the environmental change, the correct categorization is as follows:

  • Short-term changes - Fire, flood, pollution of waterways, disease
  • Long-term changes- extinction, early frost, deforestation, desertification

<h3>What are environmental changes?</h3>

Environmental changes refers to changes that occur in the environment either due to natural causes or by human activities.

Environmental changes can be categorized into:

  • short-term changes and
  • long-term changes

Short-term changes occur over a short period of time while long-term changes occur over a long period of time.

Based on the chart, the correct categorization is as follows:

  • Short-term changes - Fire, flood, pollution of waterways, disease
  • Long-term changes- extinction, early frost, deforestation, desertification

Therefore, both long-term and short-term changes occur in the environment.

PSYCHO15rus [73]

Answer:

Precentage error = 7.23%

Explanation:

The precentage error formula  is the  useful method  for determining precision of your experimental result

It can be calculated using :

percent\ error = |\frac{experimental\ value-predicted\ value} {predicted\ value}|\times 100

percent\ error = |\frac{0.077\ -0.083} {0.083}|\times 100

So we get percentage error =  7.23%

Precision means how close the experimental value to the true value or theoretical value

If percentage error is large it means experimental results are deviated and there is need to check mistakes,imprecision in the experiment

If the percentage error is zero it means the experiment is perfectly done without  inaccuracy

Lady_Fox [76]
Bleach would increase the pH because Bleach is a basic substance with a pH of about 12

Soda would lower the pH because the pH of sodas is somewhere around 2.5 (this is for coke, other sodas are a bit different)

Determine the primary means of melting that would occur at divergent boundaries, convergent boundaries, and within a plate (intr
Schach [20]

By determining the primary means of melting that would occur at divergent boundaries and the appropriate labels to the respective Convergent plate boundary.

What is the Convergent plate boundary?

As the plate delves deeper into the convergent boundary, pressure and temperature rise along with it. When the pore water is released, this contributes to partial melting.

As a result, when the situation is at the melting curve, a rise in temperature will result in a large partial melt because of the presence of water. As seen in the wet peridotite melting curves in the aforementioned curves.

Only the peridotite's temperature changes during intraplate melting, not the pressure. Therefore, as the temperature rises, it will begin to melt.

Decompression causes melting at diverging boundaries. Temperature plays no part in this. As the plate delves deeper into the convergent boundary, pressure and temperature rise along with it.
