Answer:
1. Continental-continental convergence are both <em>continental crust</em> plates.
2. Buoyancy basically means these plates are light float on top of the Asthenosphere.
Explanation:
1. To go a little more into detail, this type of convergence ocurrs when two plates made of continental crust (not oceanic) collide. In the case of ocean-continent convergence, the denser oceanic crust sinks underneath the lighter continental crust.
In this scenario, we have two plates, neither of which want to sink, so instead of going down they just crumple and fold and keep colliding. This collision creates very high mountain ranges such as the Himalaya and usually doesn't contain any volcanic activity because no magma is capable of penetrating through so much crustal material.
2. As for why continental crust is buoyant and doesn't sink has much to do with its composition. Continental crust is made mostly of silicate material. This is very different from oceanic crust which is made of basaltic rocks and is therefore heavier. The term buoyancy refers to the 'floating action' of the continental crust on top of the uppermost mantle.

Explanation:
Avoiding meat and dairy products is one of the greatest contribution people can make to help this.
If you feel you can't fully commit to this, then avoiding red meat, especially beef, will help as this industry has the greatest effect on the climate.
Ideally converting to a vegan diet would help the most.
The opening of the Panama Canal affected transportation because now, sailors didn't have to sail ALL the way around South America.
you can go too the desert and dig a hole and start by going down and u will find a place out of nowhere but you need to keep on walking and digging until u see lava when u see lava there will be diamonds and more stuff i did it before i was digging and then i saw lava and then i was walking around without touching the lava and i found diamonds diamonds are hard to find but when i see lava i always find them and if you dont then its weird
The Earth has been around for approximately 4.6 billions of years. Humans first evolved from I believe apes around 5 million years ago, with Homo Sapiens evolving around 2 million years ago or so. The current calendar system we use today, the Gregorian system (in most western nations like America) marks the year 0 as the year Jesus Christ was born, not when the Earth was formed. Years before Jesus' birth are marked as B.C., with the numbers getting higher the earlier you go. In the Japanese system, the year is marked by how long the current Emperor has been in power, making the current year (2017) Heisei 29 in traditional Japanese calendars.
