Answer:
So the Earth moves at about 110,000 km/h around the Sun (which is about one thousand times faster than the typical speed of a car on a highway!) ... This is the case for Earth's orbit. But not all ellipses come in the same shape.
Explanation:
Answer:
In order to deposit 100 meters of limestone layer, it will take 6,451,600 years
Explanation:
Given that,
The rate of deposition carbonate sediments is 1.55 cm in 1,000 years
⇒ 1.55 cm = 1,000 years
⇒ 1 cm = 
⇒ 1 cm = 645.16 years
∵ 1 m = 100 cm
∴ 100 m = 100 × 100 cm
⇒ 100 m = 10,000 cm
So, the time it will take for carbonate to deposit 100 m thick layer of limestone will be-
⇒ 10,000 cm (100 meter) = 645.16 × 10,000 years
⇒ 100 meters = 6,451,600 years
The answer to this question is C
Answer:
The answer is below
Explanation:
1. Causes: Radiogenic heat rises to heat molten magma. - Effect: Magma at the core-mantle boundary rises and convection currents are formed. This is because, the heat from the rising mantle leads to convection currents and made the core-mantle to rise gradually from bottom to top.
2. Cause: Earth is covered by a crust that runs miles deep - Effect: The mantle is insulated from the atmosphere and retains tremendous heat.
3. Cause: Tectonic plates at transform boundaries experience friction - Effect: Pressure builds up, eventually leading to an earthquake. This is because, earthquake occurs because there is tension and strain between the tectonic plates due to the energy that is released when the plates actually move.
