What do polar wander paths tell us?

The concept of apparent polar wander paths was helpful in determining the speed, direction, and rotation of continents. What do polar wander curves tell us? That polar-wandering curves for different continents (which show the paths of a magnetic pole with respect to a given continent) do not agree was one of the first important evidences

Why are mountains so tall?

Mountains often form when pressure under Earth’s surface pushes upward, yet many factors impact their ultimate height, including the erosion of the areas between mountains, known as channels. Do mountains get taller or shorter over time? This is what we call isostasy. Because of isostasy, mountains aren’t shortened as fast as they would otherwise be

What are the two different types of ocean currents and how are they formed?

Ocean circulation derives its energy at the sea surface from two sources that define two circulation types: (1) wind-driven circulation forced by wind stress on the sea surface, inducing a momentum exchange, and (2) thermohaline circulation driven by the variations in water density imposed at the sea surface by … What are the 2 types

What famous United States landform was formed by a glacier?

Yosemite National Park is famous for its spectacular glacially carved landscape. Which land forms are formed by a glaciers? Glacial Landforms and Cycle of Erosion Types of Glaciers: continental glaciers, ice caps, piedmont glaciers and valley glaciers. Ice caps are the covers of snow and ice on mountains from which the valley or mountain glaciers

How does a lahar form?

Lahars can occur by rapid melting of snow and ice during eruptions, by liquefaction of large landslides (also known as debris avalanches), by breakout floods from crater lakes, and by erosion of fresh volcanic ash deposits during heavy rains. Where is lahar from? A flood caused by a glacier, lake breakout, or heavy rainfalls can
