Earthquakes produce three types of seismic waves: primary waves, secondary waves, and surface waves. Each type moves through materials differently. In addition, the waves can reflect, or bounce, off boundaries between different layers.
The correct answer is A. Rocks are broken into smaller pieces.
Explanation:
In geography, the term weathering is used to refer to the process in which rocks and others such as soil or mineral break into smaller pieces. This can occur due to chemical agents or due to physical factors. Physical weathering includes factors such as temperature, physical contact or pressure that make rocks and other materials break in smaller pieces without changing the general properties or composition of the material. Additionally, these pieces along with other materials form the soil. According to this, the change that takes place during physical weathering is "Rocks are broken into smaller pieces".
Explanation:
Radiation means ‘energy that is transported from one spot to another without the need of direct contact between the two locations’, Light in each carries a different amount of energy, this is what we call electromagnetic radiation or electromagnetic waves. Gamma rays are the most energetic, and radio is the least.
<em>In order from longest to shortes wavelenghts we have:</em>
- Radio waves: they are made by various types of transmitters, given off by stars, sparks, and lightning, they have the lowest frequencies (longest wavelenghts) in the electromagnetic spectrum and are used mainly for communications.
- Microwaves: they are extremely high-frequency radio waves (Their wavelength is usually a couple of centimeters) made by various types of transmitters.
- Infra-red waves: they are just below visible red light in the electromagnetic spectrum, they're given off by hot objects.
- Visible lights is the tiny part of the electromagnetic spectrum our eyes can detect.
- Ultra-Violet: this light is given off by the Sun in large quantities. We call it "UV" for short and can also be used to kill microbes.
- X-rays: they are very high-frequency waves that carry a lot of energy. They will pass through most substances, and this makes them useful in medicine and industry to see inside things.
- Gamma rays: they are given off by stars and by some radioactive substances. They are extremely high-frequency waves (the shortest wavelength) and carry a large amount of energy. They pass through most materials.
In the image, I annexed you can see the electromagnetic spectrum with the type of radiations from the shortest to the longest wavelengths.
I hope you find this information useful and interesting! Good luck!
A stack or sea stack is a geological landform consisting of a steep and often vertical column or columns of rock in the sea near a coast, formed by wave erosion.<span>[</span>
The correct answer is true . Jews and arabs did lay claim to the same aincient holy lands. Such as Israel.
