"Continental drift" hypothesis that states that the continents were once one large mass that broke apart.



The continental drift hypothesis was created in the early piece of the twentieth century, for the most part by Alfred Wegener. Wegener said that mainlands move around on Earth's surface and that they were once consolidated as a solitary supercontinent. While Wegener was alive, researchers did not trust that the mainlands could move.

Match the climate zone in column 1 to the characteristic in column 2.
Aliun [14]

The correct matches are:

- A. Tropical - On the Equator;

- B. Dry - Near the Equator;

- C. Moderate - Mildest weather;

- D. Continental - Severe temperature changes;

The climate types differ from one place to another on our planet, and in general they are separated in zones in accordance to the latitude at which they are.

The tropical climate is the one that lies on and around the Equator, and it is warm and wet for the whole year. Little north and south of the Equator we encounter the dry climates, where the landscape is occupied by deserts, with extremely high temperatures, and very little precipitation. Further north come the moderate climate types and the continental climate types, they are similar to each other, but the temperatures in the moderate climates have less variation, while in the continental ones it is much bigger, also the moderate ones have more precipitation, and the continental ones have less precipitation. They are both in the mid-latitudes.

2 1. Scattering cross-section of acrosol particles is 2.5E-12 m , absorption cross-section is 0.45E- .2 12 m Concentration of pa
Alona [7]

Answer:

T = 3.23 \times 10^{-83}

Explanation:

thickness of aerosol layer is 2.5 km

zenith angle is 40 degree

we know that

\tau = \epsilon_{ext} . h

where

\epsilon_{ext} = N.\sigma_{ext}

\epsilon_{ext} is extinction coefficient

\sigma_{ext} extiction cross section

N = Concentration

\sigma_{ext} = (2.5 + 0.45)\times 10^{-12} m^2

                     = 2.95 \times 10^{-12} m^2

\epsilon_{ext} = 2\times 10^7 \times 2.95 \times 10^{-12} m^2 \times m^{-3}

                       = 5.9 \times 10^{-5} m^{1}

\tau = 5.9 \times 10^{-5} m^{-1}  \times 2.5\times 10^3 m

        = 14.75\times 10^{-2}

transimiitance T  = e^{\frac{-\tau}{\mu}}

                       T  = e^{\frac{- 14.75 \times 10^{-2}}{cos 40}}

T = 3.23 \times 10^{-83}

Much of Alaska is covered by
bija089 [108]

Answer:

the Alaska Range and the Brooks Range

Explanation:

Alaska is a federal state in the United States. It is actually the largest state of this country, and it is also the northernmost state. All of Alaska lies on very high latitude, thus it has very cold climate for much of the year.

Big portion of the landscape of Alaska is covered by two mountain ranges. These mountain ranges are the Alaska Range and the Brooks Range. Both ranges have a roughly west to east direction.

The Alaska range is located in the southern and southeastern part of Alaska. It alleviates immediately from the coastline. It separates this part of the country and the lowlands of the interior.

The Brooks Range is located between the central part of the state and the norther part of the state, being a natural boundary between the two parts. This range lifts high up between the lowlands in the interior, and the lowlands in the northern part of the state.
