what is Titicaca known for?
Lake Titicaca is famous for being the world's highest-elevation navigable lake, located in the Andes on the border of Peru and Bolivia, and it is known for its historical significance with ancient civilizations like the Tiwanaku Empire and terraced agriculture.
Explanation:Lake Titicaca is renowned for being the highest-elevation navigable lake in the world, situated in the Altiplano Region on the border between Peru and Bolivia at an elevation of approximately 12,000 feet above sea level. The lake's presence helps to moderate the regional climate, which enables agricultural productivity in what would otherwise be a harsh environmental setting. With a depth reaching over 900 feet in some areas, Lake Titicaca provides a critical freshwater resource for both agriculture and human consumption.
The region surrounding Lake Titicaca is steeped in rich historical significance, with evidence of human habitation dating back to at least 1500 B.C.E. The ancient stone site of Tiahuanaco and the Tiwanaku Empire, which at its peak may have had some 100,000 inhabitants, are testament to the advanced agricultural practices and the sophisticated societal structures that thrived here. The Tiwanaku people utilized methods such as flooded-raised field agriculture and constructed terraced farms along the hillsides of Lake Titicaca. These historical and archaeological sites, including the renowned Machu Picchu, offer a window into the ancient times when complex civilizations flourished in the Andes.
Today, Lake Titicaca remains a vital environmental and cultural resource, supporting communities that maintain a subsistence lifestyle and attracting tourists who wish to explore the remnants of these ancient civilizations. The unique combination of natural beauty and historical depth makes Lake Titicaca a place of both ecological and archaeological importance.

Explanation:
While hiking with a friend in New York State, you discover marine fossils in sedimentary strata at hight elevations. What is the most logical explanation for their presence?
Uplift is the most logical explanation for their presence in New York State with respect to the condition. Thus, option A is correct.
What are elevations?In Material Design, elevations is calculated as the separation of adjacent Material surfaces. The separation between the fronts of two Material surfaces is measured
Since marine fossils only occur in water, the presence of marine relics in the Rocky Mountains suggests that the foundation has been raised. As tectonic plates progressively drift apart, heating from the convection currents inside the mantle causes the outermost layer of rock to become less thick and more pliable. Lower-density rock rises, frequently creating mountains or raised seabed regions. Finally, the crust splits.
Therefore, option A is correct.

The 1994 conflict in the tiny African country of Rwanda was based MAINLY on
A) religion.
B) communism.
C) ethnic tensions.
D) wealth disparit
From April to July 1994, members of the Hutu ethnic majority in the east-central African nation of Rwanda murdered as many as 800,000 people, mostly of the Tutsi minority. Begun by extreme Hutu nationalists in the capital of Kigali, the genocide spread throughout the country with staggering speed and brutality, as ordinary citizens were incited by local officials and the Hutu Power government to take up arms against their neighbors. By the time the Tutsi-led Rwandese Patriotic Front gained control of the country through a military offensive in early July, hundreds of thousands of Rwandans were dead and many more displaced from their homes. The RPF victory created 2 million more refugees (mainly Hutus) from Rwanda, exacerbating what had already become a full-blown humanitarian crisis.
The 1994 conflict in the tiny African country of Rwanda was based MAINLY on Ethnic tensions. Therefore option C is correct.
What happened in 1994 in Rwanda?Up to 800,000 members of the Tutsi ethnic minority in Rwanda, a country in east-central Africa, were killed during the 1994 Rwandan genocide, also known as the genocide against the Tutsi.
The Rwandan Patriotic Front (RPF), a rebel organization founded by some exiled Tutsis, entered Rwanda in 1990. Fighting raged there until a peace agreement was reached in 1993.
On the evening of April 6, 1994, a jet carrying Burundi's Cyprien Ntaryamira and then-President Juvenal Habyarimana, both Hutus, was shot down, killing everyone on board.
From each district up to the top of the government, Rwanda has always been a carefully controlled society. Interahamwe, the youth wing of the then-ruling MRND party, was converted into a militia to carry out the massacre.
Hence, The 1994 conflict in the tiny African country of Rwanda was based MAINLY on Ethnic tensions.
