Latin america

LATIN AMERICA


Where is latin america

Where is Latin America?

  • Find Mexico on a World Map...

…and move southward


Latin america

Latin America


Why is it called latin america

WHY is it called Latin America?

And Spanish just about everywhere else!!!

Portuguese is spoken in Brazil

  • Latin is a language

  • The two widely spoken languages are Latin-based

What physical characteristics do we need to know

What physical characteristics do we need to know?

CLIMATE

  • In Central America and northern South America, it is TROPICAL

In northern Mexico and southern South America, it is TEMPERATE


Along with climate

Along with climate,

  • In the Southern Hemisphere:

  • Remember that SEASONS are REVERSED:desrever


Latin america

  • When it is winter in the USA...

…it is summer in South America (and southern Africa & Australia & Antarctica)


Weather and climate

Weather and Climate

  • Caribbean and Central America – Hurricanes

  • El Nino: cyclical climate event that involves the movement of large masses of warm water across the Pacific. Causes change in rainfall patterns.


Physical features

Physical Features

  • Mountains in Latin America:

  • Sierra Madres split along Mexico’s coasts

  • Andes along west coast of South America

  • Just like the west coast of the USA, the Andes mountains are VOLCANIC


Latin america

Mountains in Latin America can be split into agricultural “zones” as you move higher up the mountain. This is called “vertical zonation”

Snow caps

Sierra Madres

Tierra Friano crops, just grazing

Tierra Templadacrops that like temperate land

ANDES MOUNTAINS: The longLatin America Maps - Due Fridayest chain and 2nd highest mountains in the world!!

Mt. Aconcagua: Tallest Mountain in the region: 23,000 ft

Tierra Calientecrops that like hot temperatures


Latin america

Another look at Vertical Zonation in the Andes Mts.


Mountains affect on mexico city

Mountains affect on Mexico City

  • Higher elevation = colder temperatures for latitude

  • Very Heavily Polluted

    • Altitude contributes to amount of pollution

    • Mountains prevent pollution from leaving


Latin america

But California can handle the earthquakes MUCH better because of building codes and earthquake-proof structures that are built in the states. Unfortunately, Chile, Peru, and other countries in Latin America don’t follow any type of building codes and whole villages can be wiped out in an earthquake!!!

  • Along with volcanoes, western South America and parts of Central America experience EARTHQUAKES

due to the constant motion of the Earth’s tectonic plates-

Just like in California!!


More physical features

Greater (Bigger) Antilles

More Physical Features:

  • There are MANY islands in Latin America

  • The Caribbean Islands are called the “West Indies” or the “Greater and Lesser Antilles”

  • The Caribbean Islands are well known for their agriculture and tourism

Lesser (Smaller) Antilles


Latin america

  • The Galapagos Islands (off the west coast of Ecuador) are known for their Tortoises and other scientific studies of plants and animals.

Ga-LAP-ah-goes Islands

Does Charles Darwin ring a bell?


Latin america

“Falkland Islands (Isla Malvinas) Administered by the UK (claimed by Argentina)”

  • The Falkland Islands are controlled by the United Kingdom

  • The British defeated the Argentines in the Falkland Island War of 1982

  • These islands have a HUGE military advantage because of the location to the Strait of Magellan...

  • ...esp. if the Panama Canal is blocked during wartime


Other physical chars

Other Physical Chars.

Grasslands: huge, flat plains in Latin America- known for agriculture

  • The Llanos are in Venezuela; the Gran Chaco are in Paraguay; and the most famous are the Pampas in Argentina


Latin america

We’re usually found in grassland ranches…like the Llanos in Venezuela

Or the Pampas of Argentina….

where the best beef cattle in the world is raised!!

Llanos

Latin American Cowboys are called Gauchos

Pampas


Latin america

Unfortunately, we’re being cut down and set aflame to make room for interior farmland and construction!!!!

OUCH!!! This is called “Slash and Burn” Agriculture

What climate factor is responsible for this climate

Rainforests:

Costa Rica and Brazil~ Amazonia (in Brazil) is the largest in the world!

“Amazonia”

Rain forest

Rain Forest

  • Average Temp = 80

  • Avg. Rainfall = 100 in

  • Found in tropics (low latitudes)

  • Thick vegetation


Location of rainforest

Location of Rainforest


Structure of a rainforest

Structure of a Rainforest

  • 3 layers

    • Emergent Level: crowns of the tallest trees (90-120 ft)

    • Canopy: variety of broadleaf & evergreen trees (50 – 75 ft)

    • Understory: variety of shade tolerant trees (20-40ft)

  • All layers have vines and small plants growing on the branches


Structure of a rainforest1

Structure of a Rainforest

  • Only 1 – 2 % of the sunlight reaches the ground due to the canopy

    • Eliminates small plants at ground level

  • The soil of a rainforest in almost completely void of nutrients

    • Trees get nutrients from small plants that grow and decay


Benefits of a rainforest

Benefits of a Rainforest

  • Home for a multitude of species

  • Potential medicines

  • Oxygen

  • Unique human cultures: native people


Rainforest facts

Rainforest Facts

  • 25% of all prescription drugs in the US use chemicals derived from plants and animals

  • Everyday over 214,000 acres of rainforest are destroyed

  • At the current rate of destruction, 25% of the Earth’s species will be extinct by the middle of the 21st ce.


Deforestation

Deforestation

  • Cutting down of trees


Reasons for deforestation

Reasons for deforestation

  • Farmland

  • Mining

  • Animal grazing

  • Logging

  • Urbanization


Effects of deforestation

Effects of Deforestation

  • Loss of species

  • Loss of potential medicines

  • Changes in weather patterns

  • Contributes to global warming

  • Soil erosion


Alternatives to deforestation

Alternatives to Deforestation

  • Responsible companies

  • Ecotourism

  • Reforestation

  • Other means of economic development


Latin america

  • Coastal Deserts: West Coast of South America ATACAMA DESERT in Chile

This clip art is actually “wrong” to use for the Atacama…there are cacti shown!!

One of the hottest and driest places on Earth. 1/16”/yr

THIS is more like it!!!

But why can places be so dry???

The “rain shadow” effect is part of the reason

Latin america

RAIN SHADOW EFFECT

Windward side of the mountains

Leeward Side or “protected” side of the mountains

ANDES

Pacific Ocean

http://www-cs-students.stanford.edu/~amitp/simblob/rain-shadow.png

The Andes Mountains create rain shadows on leeward slopes and cause moisture to be blocked. That’s how we see such dry areas in Latin America. The Andes are so high that they block moisture from the ocean and create grasslands and deserts on the other side of the mountains.


Latin america

Orinoco River

I'm the Rio de la Plata.

I’m actually not a river, but an estuary… the large water feature where fresh water from a river meets the salt water of the sea.

Rio Grande

The AMAZON!!

The largest river in the world!!

Parana River

Rivers in Latin America


Waterfalls and lakes

Angel Falls- world highest uninterrupted waterfall

Waterfalls and Lakes

Lake Maracaibo: extension of Caribbean Sea; rich in oil reserves

Lake Titicaca: world’s highest navigable lake

Lakes in Latin America


Natural resources

Natural Resources

  • Oil found in Mexico and Venezuela

  • Gold, Silver and Copper in MX, Brazil and Chile

  • Forest Products in the Amazon


Panama canal

Panama Canal

  • Physical features make it hard to travel around. Magellan first European to sail around South America. The very southern most tip is called Cape Horn and its is famous for its severe storms

  • Shorter (thousands of miles shorter), safer route created with the Panama Canal.


Impact of panama canal

Impact of Panama Canal

  • Brought change to Middle America

  • 75000 workers built what is still regarded as one of the engineering wonders of the world.

  • Completed in 1914, the canal made a huge impact on world trade.

Impacts of physical features

IMPACTS of Physical Features?:

  • Location of urbanization?

  • People settle along coasts,

  • High population growth rate?

  • YES! Arable land means more food

  • Large cities are called: MEGACITIES

  • Sao Paulo Rio Mexico City


Latin america

And the MOST important factor from Latin America???

Of course!!!!

Didn’t YOU think coffee too?
