Answer:
A.warmer than present
Explanation:
During most of the Mesozoic Era, the Earth was warmer than present.
This is because during the Mesozoic era the land were far away from water bodies which led to prevalence of deserts while today the land are much more closer to the water bodies. It’s a known fact that water bodies help in the thermoregulation and cooling of the atmosphere.
This is the main and feasible reason why the Earth was warmer in the Mesozoic era than now.
With earths core being very very hot it is plasma which is lava but its comes closer to the surface and cools downs to become a solid.
Answer:
Yes, there are certain planet that are not detected even if they are large.
Explanation:
- The Doppler method is the radial-velocity method, and also an indirect method finding the extra solar planets and the brown dwarfs. While the transit method is a phenomenon only the celestial bodies are directly between a large body and an observer body.
- However, the transit method of the transiting planet is low as it depends on the alignment of the three objects that are in a near perfect straight line patterns. And that of the Doppler method that it can only measure movements along that line of sight, and this depends on the estimates of inclination of the planet's orbit to determine its mass.
- <u>Thus of a planet is found by both these methods we can find its density, and an indication of its composition.</u>
In Geography, when you mention characteristics, it refers to the actions and the ideas of man that changes or changed the Earth. Characteristics in Geography can also refer to as the natural and current features seen all around the Earth.
