Convections occurs because the oceanic water heats up and becomes less dense
Simplifying 4m + 9 + 5m + -12 = 42 Reorder the terms: 9 + -12 + 4m + 5m = 42 Combine like terms: 9 + -12 = -3 -3 + 4m + 5m = 42 Combine like terms: 4m + 5m = 9m -3 + 9m = 42 Solving -3 + 9m = 42 Solving for variable 'm'. Move all terms containing m to the left, all other terms to the right. Add '3' to each side of the equation. -3 + 3 + 9m = 42 + 3 Combine like terms: -3 + 3 = 0 0 + 9m = 42 + 3 9m = 42 + 3 Combine like terms: 42 + 3 = 45 9m = 45 Divide each side by '9'. m = 5
Answer:
Groundwater flows from areas with a higher water table surface to areas with a lower water table. This mixture of carbonic acid in water makes most natural surface waters slightly acidic. As slightly acidic water infiltrates the ground to become part of the groundwater system it causes weathering of the rocks.

Explanation:
White fur not only provides camouflage in winter but adds warmth. A pigment called melanin, absent in white fur, gives the fox its brown summer coat.
<h3>
What is camouflage?</h3>
Camouflage is a defense mechanism or tactic that organisms use to disguise their appearance, usually to blend in with their surroundings.
The hair shafts of white fur are hollow, trapping warm air from the animal's body heat and acting as insulation much the same way as a down coat does for a human wearer.
