For the complete encyclopedic entry with media resources, visit: http://www.nationalgeographic.org/encyclopedia/weathering/

Weathering describes the breaking down or dissolving of rocks and minerals on the surface of the Earth. Water, ice, acids, salts, plants, animals, and changes in temperature are all agents of weathering.

Once a rock has been broken down, a process called erosion transports the bits of rock and mineral away. No rock on Earth is hard enough to resist the forces of weathering and erosion. Together, these processes carved landmarks such as the Grand Canyon, in the U.S. state of Arizona. This massive canyon is 446 kilometers (277 miles) long, as much as 29 kilometers (18 miles) wide, and 1,600 meters (1 mile) deep.

Weathering and erosion constantly change the rocky landscape of Earth. Weathering wears away exposed surfaces over time. The length of exposure often contributes to how vulnerable a rock is to weathering. Rocks, such as lavas, that are quickly buried beneath other rocks are less vulnerable to weathering and erosion than rocks that are exposed to agents such as wind and water.

For example, certain kinds of air pollution increase the rate of weathering. Burning coal, natural gas, and petroleum releases chemicals such as nitrogen oxide and sulfur dioxide into the atmosphere. When these chemicals combine with sunlight and moisture, they change into acids. They then fall back to Earth as acid rain.

The hydrogen bond is one of the strongest intermolecular attractions,

Answer:

7

1

We usually get some questions about how many hydrogen bonds these compounds can create, we use it to differentiate between the boiling point of each one of them so it would be great if you could help me.

So what I know that H2O has 4 hydrogen bonds those are 2 from hydrogen atoms and 2 from other molecules that has 2 hydrogen atoms connected to the 2 lone pair of electron that the oxygen has.

In HF, It has 2 hydrogen bonds. The same explanation implies here. In NH3, 2 hydrogen bonds because N doesn't have the required amount of lone pairs to make more hydrogen bonds.

Explanation:

Answer: extra currents in the ground will disrupt power grid operations and  high-frequency radio waves used for radio communications will be blocked

Explanation:

In the case of a severe geomagnetic storm, extra currents on the ground will disrupt power grid operations and signals from radio navigation systems will be disrupted and be inaccurate.

A geomagnetic storm is caused by a CME (coronal mass ejection) from the sun that smacks against the earth's magnetic field and causes issues such as

Etc.

Extra currents in the ground caused by the geomagnetic storm will disrupt power grid operations. We can also expect a disruption of all radio signals and communications due to changes in the ionosphere during the storm.

Satellites in the Earth's orbit would likely sustain critical damage and may be rendered inoperable, however, since satellites do not use technology to stay in orbit (this is done by the earth's own gravity) they will not fall to the surface, which is why this option is wrong. The final option is also wrong because high-frequency radio waves used for radio communications will be disrupted and unreliable but not blocked.

That is why In the case of a severe geomagnetic storm, power grid operations and signals from radio navigation systems will be disrupted and be inaccurate.
