Why do small rocks weather more quickly?
GeologyLarge rocks have less surface area for their volume than small rocks. Therefore, a smaller portion of the rock is exposed to weathering. It takes longer for the rock to wear away. The small rock has more surface area for its vol- ume, so it weathers away faster. What type of rocks weather more easily?

What causes foliation in metamorphic rocks?
GeologyFoliated Metamorphic Rocks: Foliation forms when pressure squeezes the flat or elongate minerals within a rock so they become aligned. These rocks develop a platy or sheet-like structure that reflects the direction that pressure was applied. What causes foliation to occur? Foliation is caused by the re-alignment of minerals when they are subjected to high

What are the 4 eons of the geologic time scale?
GeologyFor example, the entire age of the earth is divided into four eons: the Hadean Eon, the Archean Eon, the Proterozoic Eon, and the Phanerozoic Eon. These four eons are further subdivided into eras (Table 7.3). What are the 4 divisions of the geologic time scale in order? The geologic time scale is divided into

Which of the four agents of erosion is the fastest?
GeologyWind erosion occurs when winds pick up sediment and blast these particles into rocks. Gravity is probably the fastest agent of erosion because it leads to rapid landslides and mudflows. What type of erosion is the fastest? The fastest form of erosion is moving water erosion. What is the most powerful agent of erosion? Liquid

Do all fossils come from animals that are extinct?
Geology(2) Most fossils are the remains of extinct organisms; that is, they belong to species that are no longer living anywhere on Earth. (3) The kinds of fossils found in rocks of different ages differ because life on Earth has changed through time. Are all fossils from animals? Fossils are the remains of plants, animals,

What are seismic building standards?
GeologySeismic codes or earthquake codes are building codes designed to protect property and life in buildings in case of earthquakes. The need for such codes is reflected in the saying, “Earthquakes don’t kill people—buildings do.” Or in expanded version, “Earthquakes do not injure or kill people. What does seismic mean in construction? Seismic design is
