How do Tiltmeters predict volcanoes?
GeologyMeasuring tiny changes in the slope angle or “tilt” of the ground and the shape or “strain” in the earth’s crust are time-tested methods for monitoring volcano deformation caused by moving magma. How can we use tiltmeters and GPS satellites to predict volcanoes? tiltmeters and GPS satellites – these devices monitor any changes in landscape.

What caused the Mount Pinatubo eruption?
GeologyIn March and April 1991, however, molten rock (magma) rising toward the surface from more than 20 miles (32 kilometers) beneath Pinatubo triggered small earthquakes and caused powerful steam explosions that blasted three craters on the north flank of the volcano. What tectonic plates caused the Mt Pinatubo eruption? Mount Pinatubo lies beneath a devastating

What is the topography of the ocean floor?
GeologyScience has established that the topography of the ocean floor is similar to the ground topography with features such as valleys, mountains, and plateaus. Three quarters of the Earth consists of ocean water. All these details are incorporated on underwater topography maps. What is the topographic of ocean floor called? The topography of the ocean

Why is the ocean not homogeneous and stratified?
GeologyBecause the surface and deep ocean layers are of very different densities (due to salt content and temperature), these layers of the ocean do not mix easily. The resistance of two water bodies with different densities to mix is called stratification. Why are the oceans stratified? The ocean is stratified due to differences in density,

How was the geologic time scale developed quizlet?
GeologyScientists first developed the geologic time scale by studying rock layers and index fossils worldwide. With this information, scientists placed Earth’s rock layers in order by relative age. Later, radioactive dating helped determine the absolute age of the divisions in the geologic time scale. How was the geologic time scale developed? The geologic time scale

How are fossils classified?
GeologyFossils can be placed into four main groups based on the way they formed: impression, mineralised, trace and organic. How are fossil records classified? The interpretation of the fossil record requires describing fossils, classifying them to place them in a biological context, and determining their age to give them chronological context. Fossil classification follows the
