Answer:

Hotspots occur when one of the Earth's plates moves over an unusually hot part of the Earth's mantle. These hot areas are usually relatively stationary and result in large amounts of magma rising up, piercing a hole in the plate to form a volcano. As the plates move, a series of volcanoes can form.

Answer:

0.087 g/cm^3

Explanation:

Density is Mass : Volume.

Volume = 12 x 8 x 9 = 864 cm^3

Mass = 75 g

Density = 75g/864 cm^3 = 0.087 g/cm^3

The density of a 75 g block of wood measuring 12 cm x 8 cm x 9 cm is 8.6 x 10⁻⁵ Kg/cm³.

Density is defined as the mass per unit volume of the body. Mathematically-

ρ = M/V

Given is a 75 g block of wood measuring 12 cm x 8 cm x 9 cm.

We can write -

Mass = [m] = 75 g = 75/1000 = 0.075 Kg

Volume = [V] = L x B x H = 12 x 8 x 9 = 864 cm³

Therefore, the density of the object will be -

ρ = M/V

ρ = 0.075/864

ρ = 8.6 x 10⁻⁵ Kg/cm³

Therefore, the density of a 75 g block of wood measuring 12 cm x 8 cm x 9 cm is 8.6 x 10⁻⁵ Kg/cm³.

Answer:

The greenhouse effect is a natural process that warms the Earth's surface. When the Sun's energy reaches the Earth's atmosphere, some of it is reflected back to space and the rest is absorbed and re-radiated by greenhouse gases.

Explanation:

Greenhouse gases are certain gases in the atmosphere (water vapor, carbon dioxide, nitrous oxide, and methane, for example) that trap energy from the sun. Without these gases, heat would escape back into space and Earth's average temperature would be about 60º F colder.

the warming of the Earth's atmosphere that is caused by air pollution. Note: The greenhouse effect occurs when warmth from the sun is trapped in the Earth's atmosphere by a layer of gases (such as carbon dioxide) and water vapor.

Answer:

Frequency = Velocity / Wavelength = 100 m/s / 20 m = 5 s-1 or 5 Hz.

Explanation:

The frequency of a wave with a velocity of 100 m/s and a wavelength of 20m is 5 Hz.

So, option A is correct one.

v = Frequency of wave

c = Velocity

lamda = wavelength of wave

Calculation,

Let velocity = 100 m/s

wavelength = 20m is 5 Hz.

Then, Formula: [tex]v = c/lamda[/tex]

[tex]v[/tex] =  100 m/s / 20m = 5 [tex]s^{-1}[/tex] = 5 Hz ( 1 [tex]s^{-1}[/tex]  = Hz )

So, frequency of wave is 5 Hz
