The Sahara served as a(n) _, __ the rest of the world.

2 answers:

8 0

Sahara is a desert and deserts are hard to cross. Sahara is especially bad and potentially deadly: it's very dry and there is no water to be found for miles.

Therefore it was a barrier and it has isolated South Africa from European influence for a long time. (until the time of European explorations)

Why is the global community trying to prevent climate change? List 3 reasons

guajiro [1.7K]

First Reason:

Delayed efforts to mitigate either carbon dioxide or short-lived climate pollutant emissions will have negative, and potentially irreversible, consequences for global warming, rising sea levels, food security, and public health.

Second Reason:

Due to their relatively short lifetime in the atmosphere, ranging from a few days to a few decades, reducing short-lived climate pollutants can rapidly slow the rate of global temperature rise, complement efforts to mitigate carbon dioxide emissions and keep warming below 2°C.

Third Reason:

The Climate and Clean Air Coalition’s measures can cut methane emissions by at least 40% and black carbon by up to 70% by 2030, and virtually eliminate (99.5%) high-global warming potential hydrofluorocarbons altogether by 2050 (all compared to 2010 levels).

When magma solidifies underground, the resulting landform is classified as _______.

galina1969 [7]

Answer:

1. When magma solidifies underground, the resulting landform is classified as Intrusive rocks.

2. Lava cooling on the surface of the earth forms Extrusive igneous rocks features.

3. A very large mineral is more likely to be found in Igneous rock.

4. Lava is magma that forms in long, horizontal shafts in the earth’s crust.

5. Lava with high basalt content forms high ferromagnetism through multiple eruptions.

Explanation:

1. Intrusive rock is formed when magma penetrates existing rock, crystallizes and solidifies underground to form intrusions. Intrusive rock forms within Earth's crust from the crystallization of magma.

2. Extrusive igneous rocks form when magma reaches the Earth's surface of a volcano and cools quickly. Most extrusive rocks have small crystals.

3. Igneous rock or magmatic rock, is one of the 3 main rock types. The other 2 are called sedimentary and metamorphic. Igneous rock is formed through the cooling and solidification of magma or lava.

4. Lava is molten rock generated by geothermal energy and expelled through fractures in planetary crust or in an eruption, usually at temperatures from 1.292 to 2.192 °F.

5. Mafic or basaltic lavas are best known by their high ferromagnesian content.

Eruptions associated with basaltic lava usually are not explosive due to the low silica and gas content.

Because of the low viscosity, basaltic lava flows spread out, forming extensive layers. They may build up to form a large shield volcano.
