Active transport is a process requiring energy in which a substance crosses the cell membrane. In a resting neuron, there are positively charged sodium ions outside of the cell, and negatively charged potassium ions in the cell. When the neuron fires, depolarization occurs=> the positive ions are forced in and negative ions are forced out by means of active transport. When the neuron is done firing, the ions are forced back into their original position inside or outside of the cell by active transport.

Let me know if I need to clarify any of that.

densk [106]

Answer: mechanical weathering

Explanation:

Weathering is the breaking down of rocks into small fragments or pieces by agent such as animals,water, wind. Erosion helps in the transport of this materials from its region to another.

Mechanical weathering is also known as physical weathering, it causes rocks to crumble as a results of disaggregation of rocks which could results from cracks, freeze thawing.

Water is an important agent of mechanical weathering, in either liquid or solid form.

Liquid water can seep into cracks and crevices in rock as in the case of Lurray Caverns in Virginia,and rock fragments will be eroded this materials accumulation of this leads to a new formation of calcite. If temperatures drop low enough, the water will freeze creating an expansion in the rock that could results in a crack or fragments of rocks falling off.
