Answer:
C
Sedimentary rocks can be dated using radioactive carbon, but because carbon decays relatively quickly, this only works for rocks younger than about 50 thousand years
Workers who work to preserve/help the environment. Such as people that design solar panels or farmers.
Because they are at the intertropical converge zone. Which is where air rises due to direct solar radiation causes water vapor to fall back to earth as rain.
The largest mountains on the continents are formed by stress deformation.
This is also know as strain, which is a process that occurs when the intensity of the stress is greater then the internal strength of the rock. This kind of activity, forming of mountains, occurs when to tectonic continental plates with same densities are colliding, so under the pressure, stress, they create, the area of collision is lifting up.
1. Inner core
Made of solid iron about 1,200 km thick. temperature is about 7,000 degrees Celsius.
2. Outer core
Very dense liquid of iron and sulphur about 2,250 km thick. Temperature is about 4,000 degrees Celsius.
3. Lower Mantle
Solid rock about 2,200 km thick. Temperature is about 3,000 degrees Celsius.
4. Upper Mantle
Solid rock about 720 km thick that flows from plasticity. Temperature is about 850 degrees Celsius
5. Crust
Plates that average bout 30km in thickness and 25 degrees Celsius in temperature.
