question 7 (2 points)
geology has the greatest effect on soil building?
true
false

Explanation:

Analyze the cause of earthquakes

Earthquakes are primarily caused by the sudden release of energy along geological faults, which is a direct consequence of tectonic plate movements (plate tectonics).

Evaluate planar projection for sea navigation

Mercator projection (a cylindrical projection) is the standard and most useful projection for sea navigation because it preserves angles and directions (rhumb lines plot as straight lines). Planar (azimuthal) projections are typically used for polar regions or air travel navigation, not general sea navigation.

Define ethnic group characteristics

An ethnic group is defined as a category of people who identify with each other based on common ancestral, social, cultural, or national experiences, typically sharing a common language, history, or place of origin.

Determine the primary factor in soil building

While geology (parent material) provides the mineral basis, climate is widely recognized by geologists and soil scientists as the single most influential factor in soil formation (soil building) over time, as it governs weathering rates and biological activity. Therefore, stating that geology has the greatest effect is false.
