1. Basaltic lava flows (those referred to as low viscosity flows) can travel 1-10 km/hr (0.6- 6 mi/hr) depending on the steepness of the slope of the land. Hawai'ian neighborhoods have been covered by lavas (or threatened to be covered by lava) that erupted from the Pu'u O'o vent. The vent was only 15 km (9.3 mi) from the town of Kalapana and 20 km (12.6 mi) from the town of Pahoa. Given the lava flow rates, how much time would civil defense officials (the people who decide if evacuations are necessary) have to evacuate a town if the lava flows were moving at 10 km/hr? (note 1 mi = 1.6 km)?

Answers

Answer 1

Answer:

The time will be "2 hours".

Explanation:

Around 10 km/hr, lava eruptions were travelling. The vents was just 15 km (9.3 mi) away Kalapana city as well as 20 km (12.6 mi) from Pahoa city.  

So, we therefore need add the method, which would be: to taking out another time that civil defense officials just had to assess a city.

⇒  [tex]Time = \frac{Total \ distance}{Flow \ rate \ of \ lava}[/tex]

Thus, to measure the time spent throughout the community of Kalapana,

⇒  [tex]Time=\frac{15}{10}[/tex]

              [tex]=1.5 \ hours[/tex]

The civil defense officers provide 1.5 hours of time each assess the city of Kalapana.  

In order to measure the time spent in the towns of Pahoa,

⇒  [tex]Time = \frac{20}{10}[/tex]

              [tex]=2 \ hours[/tex]

Describe how the sea erodes the coast (3 marks)

Answers

Answer:

There are three main ways in which the coast can be eroded by the sea:

Hydraulic action: lots of sea water crashes against the land, causing air and water to become trapped and compressed in surface cracks. When the sea retreats the air expands, weakening the cracks in the rock and causing pieces of the rock to break off.

Corrasion: caused by bits of rock hitting the cliffs and other parts of the land, causing more bits of rock to break off.

Corrosion: involves the chemical action of sea on rock, often happens with limestone beaches, when the limestone dissolves in the sea water although the salt can affect some other stones as well.

Explanation:

Answer:

Waves can erode the coastline in a similar way to the water in rivers. This usually occurs when the sea takes lots of energy from the power of destructive waves. Transportation - the movement of eroded material up and down, and along the coast.

State two immediate responses to a tectonic hazard that could reduce the number of deaths

Answers

A tectonic hazard would be something that isn't expected but only lasts so long.
Example: an earthquake or tsunami
The best example is an earthquake
Immediate responses would be to take shelter under a sturdy building or get to high grounds where nothing can fall on you.
The number of deaths could be reduced by having regular safety checks of buildings and if you know you are near tectonic plate shifting then the building should be built with study material.

Using complete sentences, briefly describe what the image above represents. What are the main differences between the tierra caliente level and the tierra fria level?

Answers

The image represents the various classification of Earth's environment based on the altitude.  To each zone correspond a certain type of climate, where certain types of plants for example can or cannot grow.  That's called "Altitudinal zonation".  Basically, the higher you go, the colder it gets.  That's especially useful to describe the climate in tropical but mountainous regions, like Latin America.

Difference between tierra caliente and tierra fria:

Tierra caliente (warm land) level is the lowest and goes from sea level up to 2,000 or 3,000 feet depending on who you ask, and it's the perfect for fruits and most livestock for example.

Tierra fria (cold land) level starts at 6,000 feet. It's a zone where virtually no livestock can be found and only robust vegetables (like potatoes) can grow easily.

The main differences are of course their altitude but also, as a consequence of the altitude, the types of plants that can grow in each level, which are extremely different.

Describe how population distribution affects the cultural landscape.

Answers

Answer:

The population distribution promotes a more urban or more rural natural landscape.

Explanation:

Communities with a high number of inhabitants tend to have a larger population distribution. This makes these cities consume more natural resources, reducing the rural landscape and establishing a more industrial, dynamic, urban and fast culture. These communities tend to grow and industrialize more and more, becoming more and more urban.

On the other hand, smaller communities tend to establish themselves in a more rural culture and at a calmer and more harmonious pace than urban communities. These communities are not distributed so much that they suppress their natural resources, moreover, these communities tend to decrease with the migration of their members, with the passage of time.
