What happened after the Christchurch earthquake 2011?

The earthquakes interrupted power and water supplies, three unoccupied buildings collapsed and there was again liquefaction in eastern suburbs and rockfalls in hill areas. One person died after tripping on uneven ground caused by the earthquake. What was the aftermath of the 2011 Christchurch earthquake? The Christchurch earthquake caused extensive damage to infrastructure and buildings.

What do continental glaciers do to the land?

A glacier’s weight, combined with its gradual movement, can drastically reshape the landscape over hundreds or even thousands of years. The ice erodes the land surface and carries the broken rocks and soil debris far from their original places, resulting in some interesting glacial landforms. What do continental glaciers do? Continental glaciers bury the landscape

What is fault plane?

What is the meaning of fault plane? The fault plane is the planar (flat) surface along which there is slip during an earthquake. Where are fault plane located? The fault plane is essentially vertical, and the relative slip is lateral along the plane. These faults are widespread. Many are found at the boundary between obliquely

What is not true about minerals?

Minerals are naturally occurring substances. All minerals are not non-metallic.…Detailed Solution. Metallic minerals Non-metallic minerals Metals have a high melting point They have low melting and boiling point Ductile in nature (drawn into thin wires) Non-ductile in nature Which of the following are true about minerals? To be classified as a “true” mineral, a substance

What is convergence weather?

A convergence zone in meteorology is a region in the atmosphere where two prevailing flows meet and interact, usually resulting in distinctive weather conditions. This causes a mass accumulation that eventually leads to a vertical movement and to the formation of clouds and precipitation. What is convergence in air? At the surface, low pressure systems

What type of rock is stone?

Granite is the only natural stone countertop that is made of igneous rock.…What Types of Rock Make Up Natural Stone Countertops? Igneous Metamorphic Sedimentary Granite Marble Onyx Quartzite Limestone Slate Travertine Soapstone What are stones made of? In geology, a rock (or stone) is any naturally occurring solid mass or aggregate of minerals or mineraloid

What is intensity in earthquake?

The intensity is a number (written as a Roman numeral) describing the severity of an earthquake in terms of its effects on the earth’s surface and on humans and their structures. Several scales exist, but the ones most commonly used in the United States are the Modified Mercalli scale and the Rossi-Forel scale. What is

What are the two main processes in diagenesis?

Two of the most common chemical processes found in diagenesis are cementation and dissolution. The two processes work in opposite directions, with cementation adding new material in the pore spaces between the existing grains, and dissolution removing material from these spaces. What are the processes of diagenesis? Processes in this stage are mechanical (reworking, compaction),

What is the world’s deadliest volcano?

What type of rock is chalcedony?

Chalcedony is a white, buff, or light tan, finely crystallized or fibrous quartz that forms rounded crusts, rinds, or stalactites (mineral deposits suspended from the roofs of caverns) in volcanic and sedimentary rocks as a precipitate from moving solutions. Is chalcedony a sedimentary? Chalcedony can be found in weathering volcanic rocks, but also in sedimentary
