Water & Carbon Cycles
Erosion and deposition are common in waterways. Streams with a higher gradient will experience more of one of these.
What is erosion?
What is mechanical weathering?
The process of gathering data about the surface of Earth without physically going there.
What is remote sensing?
Shield volcanoes form from this type of lava.
What is low viscosity lava?
The surface features of a landscape.
What is "Topography?"
This distinctly shaped valley is formed by glaciers carving through the mountains.
What is a U-shaped valley?
The process of dissolving rocks away.
What is chemical weathering?
This is what is represented by each contour line on a topographic map.
What is a certain elevation?
What are convergent and transform?
The breaking down or dissolving of rocks and minerals on the surface of the Earth.
What is "weathering?"
These are large rocks that are found in areas where they do not match any other surrounding rock types.
What are erratics?
Point bars and cut banks are formed by these opposing processes.
What is cut banks are formed by erosion and point bars are formed by deposition?
We can say this about an area of land that has contour lines that are very close together on the map.
What is that it is very steep?
Large volcanoes can impact the global climate because of this byproduct of an eruption.
What are aerosols?
The process in which Earth materials are transported away from their original location, usually by wind or water.
What is "erosion?"
Carbon is taken out of the atmosphere and stored at the bottom of the ocean via this process.
What is chemical weathering?
These land features are caused by the erosion of sediment by rivers.
What are valleys/canyons?
If you were marking a new hiking trail, you would probably want to stick to areas on a topographic map where the contour lines look like this.
What is spread out?
This is the technique used to find the epicenter of an earthquake.
What is triangulation? (Using seismic data from 3+ stations to find where they overlap)
Preserved physical characteristics of the past that stand enable scientists to reconstruct the climatic conditions over Earth's history.
What are "climate proxies?"
Carbon is removed from the "slow" cycle and reintroduced to the atmosphere ("fast" cycle) via this mechanism.
What is the burning of fossil fuels?
Also accepted: Volcanic eruptions
An area of sedimentary rock where the record of time is "missing" potentially because of excessive weathering and erosion.
What is an unconformity?
This remote sensing technique allows us to generate precise, three-dimensional information about the shape of the Earth and its surface characteristics.
What is LIDAR?
Cinder cones are made up of this type of rock.
What is scoria?
A large plume of hot mantle material rising from deep within the Earth, usually causing a line of volcanoes to develop as the crust moves over it.
What is a "hot spot?"
