A convergent-plate boundary to the west of North America caused oceanic crust to be subducted, causing collisions with microcontinents and the partial melting of oceanic crust to create the Sierran volcanic arc.

<h3>Give an explanation of the plate tectonic conditions that led to the formation of the Sevier thrust belt and the Sierran arc. During the Laramide orogeny, what happened?</h3>

A convergent-plate boundary to the west of North America caused oceanic crust to be subducted, which led to collisions with microcontinents and the partial melting of oceanic crust that produced the Sierran volcanic arc. Compression was responsible for the arc's folds and thrust faults. As opposed to earlier orogenies that just established the more superficial faults of the fold-thrust belts behind the arc, faulting associated with the Laramide orogeny was responsible for the creation of the Rocky Mountains. The Sevier-style orogeny may have changed as a result of the subducting slab's shallowing dip.

Considerando que a distância real entre Y a e F, duas importantes localidades, onde serão realizadas competições dos Jogos Olímp
gladu [14]

Answer:

A distância entre os dois locais importantes no mapa = 23,48 cm

The distance between the two important locations on the map = 23.48 cm

Explanation:

A proporção de escala da distância do mapa para a distância da vida real é dada como

1 : 1.500.000

Significa que

1 cm = 1.500.000 cm

Mas

1 km = 1.000 m = 100.000 cm

100.000 cm = 1 km

1.500.000 cm = 11,5 km

Portanto, a proporção da escala é corretamente

1 cm = 11,5 km

11,5 km na vida real = 1 cm no mapa

270 km na vida real = (270 × 1 / 11.5) = 23.4782608696 = 23.48 cm no mapa

Espero que isto ajude!!!

English Translation

Considering that the real distance between Y a and F, two important locations, where competitions will be held at the 2020 Summer Olympics is 270 kilometers, on a map, on a scale of 1 : 1,500,000, would that be?

Solution

The scale ratio for map distance to real life distance is given as 1 : 1,500,000

Meaning that

1 cm = 1,500,000 cm

But

1 km = 1,000 m = 100,000 cm

100,000 cm = 1 km

1,500,000 cm = 11.5 km

So, the scale ratio is properly

1 cm = 11.5 km

11.5 km in real life = 1 cm on the map

270 km in real life = (270×1/11.5) = 23.4782608696 = 23.48 cm on the map

Hope this Helps!!!

Where is most if the earth’s freshwater stored
Diano4ka-milaya [45]

Answer:

<u>In glaciers, North and South poles and some lakes.</u>

Explanation:

  • As more than 70% of freshwater can be found in continental glaciers around the world. The rest is in icecaps and 0.5 % store in lakes and rivers, and swamps.
  • Rest if possible may be found in the groundwater aquifers, hidden in remote and cut off lace of the world.  
  • Antarctica and arctic alone consist of a huge share of freshwater in the world which is stored in ice forms. While 97% of oceanic water is saline not fit for drinking.  
  • Various techniques are available for desalination of water but most of it not suitable for long term use. As it may have bacteria and harmful effects on the body. Due to climate change release of methane gas and other harmful greenhouse gases are quickly melting and depleting the freshwater r
