This dinosaur lived long ago on Earth in a tropical climate. The dinosaurs were killed and became extinct because of a change in

climate. That new climate was called an ice age. What type of fossil would we find that would support the theory that Earth experienced an ice age?

Answer:

Geological, chemical, paleontological.

Explanation:

Geological evidence for ice ages comes in various forms, including rock scouring and scratching, glacial moraines, drumlins, valley cutting, and the deposition of till or tillites and glacial erratics.

Successive glaciations tend to distort and erase the geological evidence, making it difficult to interpret.

It took some time for the current theory to be worked out.

There have been at least four major ice ages in the Earth's past.

Why does diversity increase as height above land increases​
wolverine [178]

Biodiversity rises with altitude initially before falling with height beyond that. Up until it reaches a diversity peak at about 1 300 to 1 800 m.

  • The biodiversity increases at higher geographical locations because There are more hiding locations. They are better for crop growth. They frequently include more than one kind of habitat.
  • As latitude or altitude change, so does biodiversity. As we descend from high to low elevations, the diversity increases (i.e., from poles to equator).
  • While the environment is harsh and plants have a brief growing season in the temperate region, tropical rain forests provide year-round growth-friendly circumstances.
  • This enables the emergence and expansion of several species. On a mountain, there is an initial increase in species diversity after which there is a decline in species variety as you go up in elevation.
  • At higher elevations, temperature drops and seasonal variations increase, which significantly diminishes.

The atoms of different phosphorus isotopes __________.
Jlenok [28]

Answer:

Have different numbers of neutrons

Explanation:

Isotopes of an element have different atomic numbers because thy differ in neutron number even though proton number remains the same across the isotopes. The mass number is the summation of the proton and neutron number. Phosphorus has approximately 23 isotopes whose mass number range between 25 and 47. Only ³¹P is stable.
