These changes can be natural, such as through variations in the solar cycle.

Oldest rocks in the world
5. 3.8 billion years ago
Tree cores

With this information we can conclude that these changes may be natural, such as through variations in the solar cycle. But since 1800, human activities have been the main driver of climate change, mainly due to the burning of fossil fuels like coal, oil and gas.

Explanation:
New ocean crust is formed at the mid ocean ridges. The new crust is then pushed away from the ridge as newer crust comes to the surface. The ocean crust then spreads out enlarging the ocean. The farer away from the ridge the ocean crust is the older the crust
Answer:
True.
Explanation:
The unequal distribution of ions inside and outside of the cell makes the membrane potential of the cell. The potential is important for the conduction of the impulse and generation of the action potential.
The resting membrane potential of the nerve impulse is maintained by the presence of large potassium ions inside the cell. The resting membrane potential is -70mV. The depolarization of the membrane occurs due to influx of the sodium ions.
Thus, the answer is true.
