Weathering 1
Small bits of rocks and minerals that have been eroded
What are sediments?
What are body and surface waves?
What are the science words that rocks do in hot and cold temperatures that mean to swell/get bigger and shrink/get smaller?
What are expand and contract?
These are defined by climate, landforms and soil characteristics.
What are ecoregions?
Where the earthquake originates within the earth
What is the focus?
The breaking down of rocks without changing the rock's chemical composition
What is physical or mechanical weathering?
These waves travel back and forth.
What are P waves?
The process that moves bits of weathered rock or soil from one place to another
What is erosion?
The process in which sediments, soil, and rocks are added to a landform
What is deposition
The method that scientist use to determine where the epicenter is.
What is triangulation?
What type of river is described as having less energy, slower, meandering
What is a mature river
These waves travel through the crust and mantle but not through the outer core. What are they and why?
What are S waves and because the outer core is liquid?
Name the four ways that erosion occurs by
What is gravity, water, wind, and ice (glaciers)
Name three of the four different landforms that are the result of deposition
What are deltas, flood plains, sandbars and dunes
What can result along shorelines after an earthquake takes place along the plate boundaries under the ocean.
What is a tsunami?
The type of chemical weathering that results in softened minerals or changing the minerals in the rock due to water
What is hydrolysis?
These are boundary types that result in earthquakes and volcanoes.
What are transform and convergent (subduction zones) boundaries?
This type of chemical weathering is the result of oxygen mixing with the iron in the rock
What is oxidation that causes rusting?
What is carbonation and/or dissolving? This results in caves.
The scale that scientists use to measure the strength or the magnitude of an earthquake.
What is the Richter Scale?
Name the 4 of the five ways that physical weathering occurs
Abrasion (glacial/ice or ice wedging); plant roots, burrowing; temperature change; gravity
These waves are almost entirely responsible for the damage and destruction of the earthquake.
What are surface waves?
The type of physical weathering that results because of rapidly moving water or glaciers
What is Abrasion (Glacial/ice)
What is the difference between weathering and erosion
Weathering is responsible for breaking down rocks to sediments and erosion is responsible for moving/transporting the sediments
Explain triangulation
Three seismographs use their data (the time difference between P and S waves),which provides a distance from each station. The intersection of the three circles gives the epicenter.
